Question

Classify each of the following as homozygous dominant, heterozygous, or homozygous recessive.

Answer 1

First, we will elaborate the terms that are being used.

Heterozygous:
This means that the organism has a set of alleles which are different from one another. One copy may be for the dominant trait and the other for the recessive one.

Homozygous: 
The organism has two copies of the same allele

Dominant:
An allele that will express itself even if only one copy of it is present. These are usually represented by capital letters.

Recessive:
An allele that requires both copies to be expressed. These are usually represented by lower-case letters.


A: Heterozygous

B: homozygous recessive

C: Homozygous dominant

D: Homozygous recessive

E: Homozygous dominant
