Question

If an organism possesses two recessive alleles, the term homozygous can be used to describe its genotype, and it will exhibit a recessive phenotype. This statement is referring to:

a) Codominance
b) Incomplete dominance
c) Homozygous recessive
d) Heterozygous dominance

Answer 1

The organism described with two recessive alleles is known to be homozygous recessive and will exhibit the associated recessive trait. The option (C) is correct.

Step-by-step explanation:

If an organism possesses two recessive alleles, it is described as being homozygous recessive. The term homozygous is used when an organism has two identical alleles for a specific gene, which can be either dominant or recessive. The condition is referred to, where an organism exhibits a recessive phenotype when it has two recessive alleles, is homozygous recessive.

Alleles can exhibit different patterns of inheritance, such as codominance and incomplete dominance, which are different from the dominant-recessive inheritance described in the question. In codominance, both alleles in a heterozygote are equally expressed, while incomplete dominance results in an intermediate phenotype. However, these terms do not apply when discussing an organism with two identical recessive alleles that express the recessive trait. Therefore, option (C) is correct.
