Hi I'm pretty sure the answer is A, but I'm not completely positive. Am i correct?
Which of the following pairs of words can be used correctly to describe alleles?
A) dominant or recessive
B) homozygous or heterozygous
C) genotype and phenotype
D) codependent and mutation
Posting one time is sufficient. This post is here 4 times.

Yeh because I meant to post 4 times at the same exact one time.......so excuse you
To determine the correct answer, we need to understand the meaning of alleles and the words provided in each option.
Alleles refer to the different forms or variants of a gene. They can exist in different combinations and result in various traits or characteristics in organisms.
Let's evaluate each option:
A) "Dominant" and "recessive" are terms used to describe the expression or behavior of alleles. Dominant alleles are expressed in the phenotype when present, while recessive alleles are only expressed in the absence of a dominant allele. These terms are indeed correct in describing alleles.
B) "Homozygous" and "heterozygous" describe the presence of either identical alleles (homozygous) or different alleles (heterozygous) at a particular gene locus. These terms are also correctly associated with alleles.
C) "Genotype" refers to the genetic makeup of an organism, specifically the combination of alleles it possesses. "Phenotype" refers to the observable traits or characteristics resulting from the interaction of an organism's genotype with its environment. While these terms are related to alleles, they describe different aspects and are not directly used to describe alleles themselves.
D) "Codependent" and "mutation" do not directly relate to alleles. "Codependent" implies a relationship or connection between two variables, but it is not a term specifically used in genetics. "Mutation" refers to a change in genetic material, such as a alteration in a gene sequence, but it is not related to the specific definition of alleles.
Based on the evaluation, the correct answer is B) "homozygous or heterozygous," as these terms are specifically used to describe the different combinations of alleles at a particular gene locus.
