What determines how many phenotypes exist for a particular trait?

What determines the phenotype of a trait?

Phenotype is defined as an organism’s expressed physical traits. Phenotype is determined by an individual’s genotype and expressed genes, random genetic variation, and environmental influences. Examples of an organism’s phenotype include traits such as color, height, size, shape, and behavior.

How do you determine the number of phenotypes?

There is a range of phenotypes, but most of the offspring are similar in color to the parents. If n = the number of gene pairs, then (2n + 1) will determine the total number of categories of phenotypes.

Where do phenotypic traits come from?

The phenotype is dependent on the genetic make-up of the organism, and also influenced by the environmental conditions to which the organism is subjected across its ontogenetic development, including various epigenetic processes.

What factors affect phenotype?

Environment Can Impact Phenotype

Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal’s genes are expressed, which ultimately affects the animal’s phenotype.

How many phenotypes are possible?

A fetus receives one of these three alleles from each of its parents. This produces four possible phenotypes (blood types) and six possible genotypes.

How many phenotypes and genotypes are possible in f2 generation?

Phenotypes-4; Genotypes-9.

How do you calculate phenotypic percentage?

Count the total number of boxes in your Punnett Square. This gives you the total number of predicted offspring. Divide the (number of occurrences of the phenotype) by (the total number of offspring). Multiply the number from step 4 by 100 to get your percent.

How do you determine phenotypic plasticity?

Phenotypic plasticity refers to the ability of a genotype to express different phenotypes depending on the environment in which it resides. For example, genetically identical water flea (Daphnia) clones can differ in their morphology depending on whether reared in the absence or presence of a potential predator.

What are the two main factors responsible for phenotypic variation?

Two types of factors are recognized as contributing to the phenotypic variation in a population, genetic and environmental.

How does the phenotype depend on its genes?

An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. For example, differences in the genotypes can produce different phenotypes. …

What determines or contributes to your phenotype quizlet?

your genotype is what makes your phenotype. your base sequence of a gene is what determines your allele- dominant or recessive, your two alleles determine ypur genotype, your genotype determines your phenotype. an organism’s genotype determines theor phenotype, because the genotype has the genes.
