Genotype Research Paper

Genotype: The make-up of alleles for a particular trait in an organism. For example, if black was a recessive trait in chickens, coded for by b, and there was a black chicken, its genotype would be bb.

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.

Traits get passed down from one generation to the next through Meiosis (cell division), where each parent gives you one Gene for each trait.

Good afternoon Dr. Martinez and Classmates, The family genogram can be applied to the treatment of a family with addictions issues. The family genogram is an assessment that the counselor can used before starting treatment with the family. The counselor can work with the family by creating the genogram and finding more information about the family. According to Murdock (2013) states, “The genogram is the primary method of formal assessment in BFST.

Genetics Case Study Part A: Recognize and Recall 1.) A Haplotype is a group of genes. These genes are within an organism; a single parent inherited these genes. An example could be Karen and her husband. This word almost sounds like haploid.

For exhibition this year, everyone chose an inherited trait to trace back in their family. This allowed the eighth graders to expand their knowledge of genetics and simple inheritance. The purpose of the project was to try and find the genotype of our family members. In order to do this, we had to contact the members of our family and ask them their phenotype; if they have the trait or not. Then we found the genotype of as many family members as possible using the pedigree process. The trait that I chose is called Darwin’s tubercle. It is a bump on the cartilage of the ear that some people have. I chose this trait because my father, sister, and I have it, and I was wondering if anyone else in my family had it. There are two possible phenotypes for this trait; either you have it, which is the dominant trait, or you don’t, which is the recessive trait.

Genetic variation is a topic that has come towards the forefront of discussion as we learn more about genetics. Genetic variation is the variation of alleles in the gene pool. Specifically, in this paper, I will be focusing on the genetic variance of large population sizes and small population sizes in the same species. It has become widely accepted that if the population size is smaller than the genetic variance is smaller as well, thus leading to these smaller populations not being able to adapt to changing environments. This paper will be looking at how population size has no effect on genetic variety in a habitat generalist species, while a smaller population size in a habitat specialist species will have lower genetic variance.

Your personal DNA is a factor in your phenotype, but it is not the only factor. Environmental factors plays a major role in your phenotype with determinants such as climate, population of the species, and outside species involved in that specific food chain. An example of this is the skin tone in humans. Humans that live closer to the equator tend to have darker skin tones as opposed to people that live far way to the equator have lighter skin tones. This has to due to the human ability to produce vitamin D and how skin reacts to the sun. Another example is the thick fur of mammals that live in the snow. They have adapted to regulate their temperatures better according to their climate. If there is a disturbance in the food chain because of

To be able to produce an albino baby, the parents need to have a genotype Aa. Therefore if you draw a punnet square you will be able to see that there is actually a 25% chance to have a child with a genotype AA. As shown in the punnet square below

Polygenic traits are formed by two or more genes which conjure the phenotype of an organism. In addition, the environment also contributes to the phenotype of the organism. Geneticists refer to this as multifactorial, meaning that many factors, both genetic and environmental, collectively influence the phenotype. This prior knowledge of understanding heredity aids us to conclude whether males are generally taller than females.

Offspring differ somewhat from their parents and from one another. Instructions for development are passed from parents to offspring in thousands of discrete genes, each of which is now known to be a segment of a molecule of DNA. This essay will explore some of the reasons behind how and why these differences in appearance arise, from the base sequence of DNA through to the observed phenotype.

Genetic mutations are permanent changes to a cells DNA. DNA and RNA (ribonucleic acid) are chemical blueprints for your entire body. Every living organism has genetic materials that controls all of its body 's functions. It also determines many physical traits. Eye color is completely formed by genes but in fact, height is established by genes plus environment. Such as past generations heights. Genetic code can change over time, but most of the time it doesn 't effect you because it 's protected by DNA repair so they don 't become permanent mutations. When the changes are strong, the DNA repair is to week to handle it so the changes unfortunately become permanent, which signals that it 's going to effect you and it 's deleterious.

It is easy to see that there is some differences from one person to the next. These differences can be hair color, eye color, skin color, facial structure, eye structure, etc. These different characteristics are polygenetic traits: hair color, eye color and skin color. Polygenetic trait is multiple genes mixing with each other to create the characteristics like blue eyes. The eye color is controlled through the genes from both parents that are passed through to their child. Scientist have found that there is multiple genes that decide what color the eye needs to be or will be. The color of the eye is often slightly or way different from one person to the next. The color of the eye has the function of controlling how much light enters the eye.

Heredity – the transmission of traits from one generation to another, from parents to offspring; the protoplasmic continuity between parents and offspring

Genes build the phenotype of humans as well as the underlying genotype. Competition between cultural genes leads to varied success of genetic determinism. It can therefore be said that learnt traits such as those espoused within a specific culture, can produce what may seem to be the genetic genotype of an individual. Genes are not always advantageous in the
