Genotypes In Children

Phenotype: The physical appearance of a trait in an organism. The phenotype of the above chicken is that it is black. A phenotype could be that a person has blue eyes, or curly hair.

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.

Phenotypes are known as the observable traits of a person. These traits that we are able to see are determined by the interactions between our genes and our environment. However, many people notice these phenotypic differences and put their own ideas or meanings about particular groups like races.

The way genes are arranged in each cell within us determine the different features that we have, physical attributes like eye color, hair color, ear size, height, and other traits. However, it is still not known whether the more complex attributes like personality, intelligence, sexual orientation, likes and dislikes are gene-coded in our DNA, too. Some philosophers such as Plato and Descartes suggested that certain things are inborn, or that they occur naturally regardless of environmental influences. Nativists take the position that all or most behaviors and characteristics are the results of inheritance. Advocates of this point of view believe that all our characteristics and behaviors are the result of evolution. Genetic traits handed down from parents influence the individual differences that make each person unique.

Everyone has traits, but how do we get them? Your genotypes determine your phenotype (or trait). To determine your genotype, you use the alleles given from each parent. If an allele is dominant then it is expressed by a capital letter, and if it is a recessive allele then the letter is lowercase. Your genotype can be expressed in different ways, Homozygous Dominant (EE), Heterozygous (Ee), and Homozygous Dominant (ee).

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

Genetics is the study of genes, genetic variation, and heredity of living organisms. Genes are the sets of chromosomes combined from the mother and father formed into the new set for the offspring. Sets of alleles forming the traits given to an offspring are called either genotypes, or when observable outwardly on the progeny they are called its phenotype. Traits are heterozygous as a gene with one allele is dominant, as its qualities dominate the phenotype of the organism, and the other allele is recessive. Recessive alleles qualities recede and are not observed over the dominant allele. Some alleles do not have complete dominance and instead have incomplete dominance by expressing an intermediate phenotype, or codominance by expressing both alleles at once. Combinations of traits and genes make up the different faces and characteristics seen in our world and communities. One person even if related, unless from identical chromosomes, will not ever look the same as another human being (Tortora & Derrickson, 2008).

There are many terms used by geneticists. The most simple is the word trait. Traits are characteristics that come from one’s genes; they can be inherited, meaning that they come from an organism’s parents. Genes are much like blueprints for what an organism will be. Genes can be either dominant or recessive (dominant genes overpower recessive ones). Genotypes are, put as intelligibly as possible, the type of gene that one has for each trait that he or she owns. An allele is a trait that an organism gains from one parent. One gets two alleles for each phenotype (a physical trait). An organism is either homozygous dominant for a phenotype (it has two of the same dominant alleles),

The Human Traits Lab was meant to investigate certain traits that family, myself and peers exhibit. Phenotypes, such as widows peak, tongue roller, were to be determined and then compared with other peers. To begin to understand the lab an important concept must be explained first. Inheritance is defined as the passing of genes from parent to offspring. Each person inherits one allele from each parent to determine their genotype. The concept Mendel’s Principle of Inheritance includes four distinct inheritance patterns. The first is complete dominance, in which one allele beats the other. The dominant allele is represented by a capital letter while the recessive allele is represented by a lowercase letter. For example if the genotypes were TT

Interactions with children and their caregiver have shown to be very significant because of the genetic link that associates to having a positive relationship with one another. Relationships between parents or caregivers can affect a child’s state of mind and certainly help them in the future, for example with their cues (Senese, 2017). The role of being a caregiver can influence a child on becoming the kind of individual that a parent is reflecting upon them by their actions. This function happens since parents contain different molecular genes that lead to developing different hormones and can have a variety of effects on a child (Bakermans-Kranenburg, 2008). Human parenting has the control of reinforcing numerous emotions to their child by naturally spreading their genetic

Genotype is the genetic information included in the DNA of a living thing. (Page 197)

Genotype, or nature, is the genetic coding of one's DNA. Genetic code can determine things like eye color, hair color, and height. Phenotype, or nurture, is the actual appearance of these traits which may be different than the genotype due to environmental factors. Scientists have disagreed about how much effect genotype has on the phenotype of psychological traits such as intelligence, aggressiveness, happiness, and the appearance of psychological disorders (Rathus, 56).

Phenotype of a person takes shape by his or her genotype and the article titled “New Genes as Drivers of Phenotypic Evolution” is based on that idea because primary source of phenotypic diversity is genetic diversity. Chen et al.(2013) state that evolution of the genome may happen in various ways for example alteration to coding and non-coding sequences, which is known as occurrence of new genes. Chen et al.(2013) say that new genes are the genes that appeared in a specific time during evolution at a locus which did not exist before. They add that new genes may affect and help that genetic diversity as the basic unit of genetic material. There are a lot of ways to generate new structure. Chen et al.(2013) state that new gene expression

There are many different type of genes that determine many traits such as a person’s eye and hair color. Certain traits are hidden and can skip generations until they finally reappear when a parent is a carrier to that gene. Each person receives two copies of a gene, one from their father and one from their mother. The dominant gene is the one that will show up since the recessive gene is weaker. Two dominant genes will result in the child inheriting the dominant gene. A person that receives one dominant copy and one recessive copy will inherit the dominant gene. The only way to inherit the recessive gene is if a person obtains a recessive copy from each parent, thereby allowing hidden traits to reappear. Capital letters symbolize a dominant gene while lower case letters symbolize a
