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
Please refer to your latest post, which I saw and answered first.

To determine the correct answer, let's break down the question and analyze each option:
A) Dominant or recessive: Dominant and recessive are terms used to describe the expression of an allele in the phenotype of an organism, but they do not directly describe alleles themselves. Therefore, A is not the correct answer.
B) Homozygous or heterozygous: Homozygous and heterozygous are terms used to describe pairs of alleles at a specific gene locus. Homozygous means having two identical alleles (e.g., AA or aa), while heterozygous means having two different alleles (e.g., Aa). Hence, B is the correct answer.
C) Genotype and phenotype: Genotype and phenotype are terms used to describe different aspects of an organism's characteristics related to alleles. Genotype refers to the genetic makeup of an organism, specifically the combinations of alleles it carries, while phenotype refers to the observable physical or biochemical traits resulting from the interaction between an organism's genotype and its environment. Therefore, C is not the correct answer.
D) Codependent and mutation: Codependent and mutation are not directly associated with alleles. Codependent typically relates to interdependent relationships between organisms, and mutation refers to changes or alterations in the genetic material of an organism. Thus, D is not the correct answer.
Based on the above analysis, the correct answer is B) Homozygous or heterozygous. These terms appropriately describe pairs of alleles at a specific gene locus.
