What are two things that determine your phenotype?

What are two things that determine your phenotype?

An organism’s phenotype results from two basic factors: the expression of an organism’s genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype.

What are phenotype determined by?

The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

What 2 things does a Punnett square predict?

The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring.

What are 3 examples of phenotypes?

Phenotype Examples

• Eye color.
• Hair color.
• Height.
• Sound of your voice.
• Certain types of disease.
• Size of a bird’s beak.
• Length of a fox’s tail.
• Color of the stripes on a cat.

How do genes determine phenotypes?

An organism’s genotype determines its phenotype. Diploid organisms inherit two alleles for each gene; one allele from each parent. Interactions between alleles determine an organism’s phenotype. If an organism inherits two of the same alleles for a particular trait, it is homozygous for that trait.

How do genotype determine phenotype?

Genotype & Phenotype. Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). In a narrow “genetic” sense, the genotype defines the phenotype.

What are the phenotypes of the offspring YY?

Answer: YY is the homozygous dominant genotype (2 Y alleles). The phenotype of this genotype is yellow seed color. Yy is the heterozygous genotype (one dominant allele, one recessive allele).

How do you determine the number of phenotypes?

The number of different genotypes is 3 n where n = number of genes. For simple dominant–recessive relations, the number of different phenotypes is 2 n , where n = number of genes.

What are 2 examples of genotypes?

Other examples of genotype include: Hair color. Height. Shoe size….Genotype examples

• A gene encodes eye color.
• In this example, the allele is either brown, or blue, with one inherited from the mother, and the other inherited from the father.
• The brown allele is dominant (B), and the blue allele is recessive (b).

How are the genotypes and phenotypes of the offspring determined?

A Punnett square is used to lay out the possible genotypes of offspring based on the genotypes of the parents being bred. From this, the probabilities of certain phenotypes and genotypes can be determined.

How does natural selection affect the distributions of phenotypes?

The three ways that natural selection can affect the distributions of a phenotype are that organisms and their offspring have a variation in their phenotypes and genotypes, favorable variations survive and are passed on to offspring, and, organisms reproduce more offspring than could possibly survive. Can phenotypes OB produce genotypes As?

How are genotypes and phenotypes determined using Punnett squares?

One parent’s alleles are listed across the top of the table, and the other parent’s alleles are listed down the left hand side. The resulting offspring genotypes are produced at the intersection of the parent’s alleles. With the results of the Punnett square, the probabilities of specific genotypes and phenotypes can be determined.

Can a heterozygous individual produce a dominant phenotype?

A heterozygous individual crossed with a homozygous dominant individual will always produce offspring with the dominant phenotype. Otherwise, a heterozygous individual crossed with a homozygous recessive individual will always produce offspring with a phenotypic ratio of 1:1.
