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

To determine the correct answer to this question, you can break down the options and analyze their meanings.

A) "Dominant or recessive" refers to the types of alleles that determine how traits are expressed in a genetic organism. Dominant alleles are those that are expressed or observed in the phenotype when present, while recessive alleles are only expressed if there are no dominant alleles present at the same locus.

B) "Homozygous or heterozygous" describes the genetic composition of an organism at a specific locus. Homozygous means having two identical alleles for a particular gene, while heterozygous means having two different alleles at the same locus.

C) "Genotype and phenotype" are commonly used terms in genetics. Genotype refers to the specific alleles an organism possesses at a particular gene or set of genes, while phenotype refers to the observable characteristics or traits of an individual resulting from its genotype.

D) "Codependent and mutation" do not specifically refer to alleles.

Based on the definitions provided, the correct answer is B) homozygous or heterozygous, as these terms accurately describe the genetic composition of individuals at a specific locus.
