Phenotype Varying

Introduction: In this frog population, traits such as eye color, skin color, and the presence or absence of spots are coded for by DNA. The nitrogenous bases in a strand of DNA make up an organisms genotype. The physical expression of the genotype is the phenotype.

Biology, the study of life and living organisms, is complex and encompasses a multitude of theories and ideas. In AP Biology, the fourth unit covered was genetics. Chapters 11, 12, 13, 14, 15, 16, and 18 in the textbook, Campbell’s Biology in Focus, not only discusses the four main ideas of biology: evolution, energy, information, and systems, but it also gives examples of each in order to help guide the reader’s understanding of the concepts.

Both genetic and environmental factors affect your phenotype. Traits that are primarily attributed to genetics are height, weight, eye color, hair color, and hair texture. All traits are influenced by the environment to some extent. While genetics are primarily responsible for what you will look like, the environment definitely has some impact on your phenotype as well.

Generalist Genes Hypothesis- genes that affect one ability are largely the same genes that affect other abilities, even though there are some genetic effects that are specific to each ability.

The goal of this experiment is to discern the dihybrid inheritance patterns of traits in dragons, specifically color and breath weapon. The specific traits being studied are Red and Gold coloring and Acid and Gold mouth weapons. Scientists have concluded that by investigating the results of crosses of two parent organisms, the inheritance pattern can be discovered by interpreting the resulting phenotypes. The aim is to decide if the inheritance pattern is simple dominance, lethal alleles, or sexual linkage.

Genetic and genomic variations are being taken into consideration when referring to nursing interventions for patients. In the discussion paper, “Individual Genetic and Genomic Variation: A New Opportunity for Personalized Nursing Interventions” by Munro (2014), the author examines the potential for genetic and genomic variations being incorporated into nursing interventions for patients. According to Tremblay and Hamet, “Genomics include interactions among genes, intergenic regions, epigenetic factors and environmental factors” (As cited in Munro, 2014, p. 36). The study of these genomics revealed that genomes are able to respond to environmental influences. Complicated genome-environmental interactions could be presented by cancer, diabetes

Albinism is recessive to pigment. Cystic fibrosis is a hereditary disorder caused by a recessive allele. Traits that are expressed through genes can be inherited. Nature vs. Nurture is characteristics that are acquired through environmental influences, such as injuries or practical skills. Gregor Mendel was the father of genetics. He studied pea plants. He studied two distinct forms of traits. Two examples of this is stem height, and pod shape. His work was recognized in the 20th century. The rediscovery of his work prompted prompted the foundation of genetics. Scientist use punnett squares to show probability in genetics. Codominant is what we call alleles that are equally strong. Different capitalized letters with a base letter is how codominant alleles are written. An incomplete dominance is known as partial dominance. The traits that are expressed in incomplete dominance by blending of the traits. You represent incomplete codominance genotypes by using two different capital letters. The male determines the sex of a child. Sex-linked traits are located in the x chromosomes, in the human genome. Three sex-linked traits in humans are colorblindness, hemophilia, and

“An organism's genotype is the collection of genetic variants it possesses. Its phenotype, by contrast, is its traits -- visible features of the organism like eye color, hair color, height and so on. Some traits can be affected by environmental factors” (Brennan). Cells copy their DNA when they divide and both daughter cells inherit an identical copy. Your genes carry the instructions for the growth and development of your body. However, your phenotype is influenced during embryonic development. For example, if you're malnourished as a child, your height at adulthood may be shorter than what you would predict based on your genes alone. Consequently, there can be more than one phenotype for the same genotype. Natural selection acts on phenotypes, so it only acts on the genotype indirectly. Phenotypes are driven by DNA because they represent the genetic makeup, the genotype. Phenotypes are the observable features of the genotype that is

The ability of an organism to surviveal in a changing and unpredictable environment is largely related to its phenotypic plasticity. Overall, this concept is defined as the ability of a single genotype to manifest a range of phenotypes in response to variations in the environment [1, 2], and it is often considered adaptive because can increase individual fitness [1, 2, 3]. Plasticity embraces not only the flexibility in morphological traits, but also in behavior, life history, physiology, biochemistry, and virtually any trait [1, 2]. Behavioral flexibility is a crucial component of the phenotypic plasticity that allow that individuals change the types and amount of behaviors in space and time, according to the environment pressures [1, 2, 4].

Phenotype are more specifically be observed as anatomical, morphological, physiological, and behavioral characteristics. Phenotype can also represent what can be as an extended phenotype. Which is what natural selection interacts with distinguishing among genotypes. Thus in which, genes interact with environment and the production of genotype typically involves the protein molecules as template by DNA. The process of phenotype generation typically involves the copying of DNA based information into RNA information. RNA based information is then copied into amino acid based information. I have chosen my paternal grandfather with a dominant phenotype for his skin color. I predicts that my paternal grandfather genotype for his skin color give his off spring a higher possibilities to possess a same skin tone that is along pass from my father to me. I would go about testing my hypothesis by observing my paternal uncle and aunt to see if they possess the same skin tone as my paternal

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Genotype refers to the information contained in an organisms DNA, or genetic material. Its phenotype is the physical

Similarly, phenotypic variability is influenced by environmental factors, genetic factors, and relation of an environment with genetic components. These factors can overall lead to changes in a population. Changes in an organism genes can lead to adaptation to increasing the organism survival and reproductive success. The environment will apply pressure to forcing an organism to develop ways to cope. The environment is able to affect individuals in a population even in the absence of genetic differences. The possibility of knowing the genotype of an organism has allow mathematic model to compute value for traits to predict the phenotype. Quantitative traits are represented by values cause by one gene or group of genes. The book indicates that it is confusing to think of a trait of having only one gene because multiple genes can produce that trait. And therefore quantitative traits can be deceptive in giving sign for blending inheritance. These traits are affected by many alleles which cause them to change continuously in many

Mendel found out that organisms can have the same phenotypes, but have different underlying genotypes.

Every human in the world is born with a unique set of DNA molecules, that carries genetic information and controls many characteristics of the body. All of the genetics inherited come from a childs' biological parents. There are two different types of genes, one is dominant and one is recessive. The dominate gene determines the organisms appearance and the recessive gene has no obvious effect on an organisms appearance. The phenotype is affected by the inherited genes and the outside environment. Genotypes are only affected by the inherited genes from the biological parents. Genes are found in the nucleus of every living cell in the body.

There are many issues today involving genetics and inheritances; therefore, I want to introduce this subject to students and allow them the opportunity to learn about it. Before students begin this genetics heredity unit they should have a basic understanding of DNA, cellular reproduction, and the process of mitosis and meiosis. Additionally, this unit will contain activities that require students to expound upon critical and higher order thinking skills; I believe these skills can prepare students for the kinds of issues they may encounter in the world in the future.
