How can a poly genic trait be easily identified

Biology
1 answer:
I am Lyosha [343]3 years ago
5 0

Answer: The presence of the polygenic trait masks the other possible alleles involved. There are only two possible phenotypes for the trait. The graphing of the possible phenotypes results in a bell curve. Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall.

Which statements describe the inheritance of traits? Select three options.
liraira [26]

Answer:

<u><em>The correct options are:</em></u>

<u><em>All traits are inherited.</em></u>

<u><em>Offspring inherit one allele for a gene from each parent.</em></u>

<u><em>An offspring with two identical alleles for a trait is homozygous.</em></u>

Explanation:

  • In the biological world, a trait can be described as a genetic characteristic which makes up an organism. Every organism has a particular set of traits.

  • Traits are inherited from parents, however they can be influenced by the environment.

  • The alleles of a gene make up the genotype and the influencing phenotype. An organism acquires one allele for the gene pair from each parent.

  • When both the alleles of a gene pair are similar, the organism is said to be homozygous for the trait. If both the alleles of a gene pair are different, the organism is said to be heterozygous for the trait.
