Question

How are a heterozygous and a homozygous individual different?

a. All of the gametes from a homozygote carry the same version of the gene while those of a heterozygote will differ.
b. Homozygotes have one chromosome while heterozygotes have two similar chromosomes.
c. Heterozygotes carry two copies of a gene while homozygotes only carry one.
d. The homozygote will express the dominant trait and the heterozygote will express the recessive trait.

Answer 1

Option (a).

Step-by-step explanation:

Homozygotes individuals has the same genotype whereas the genotype of the heterozygotes are different. The homozygotes may refer the true or pure organism.

The gametes obatined from the homozygotes caaries the same gene. The gametes of the heterozygotes carries the different version of the gene. The dominant trait will express themselves in the heterozygotic condition.

Thus, the correct answer is option (a).
