Question

match each term to the correct choice. use each answer once.
1 heterozygous 2 genotype 3 dominant
4 homozygous 5 recessive 6 phenotype
match each of the options above to the items below.
pp and pp
pp
p
p

Explanation:

Step1: Analyze "PP and pp"

PP has two identical dominant alleles, pp has two identical recessive alleles. So they are homozygous. So "PP and pp" matches with 4. Homozygous.

Step2: Analyze "Pp"

Pp has one dominant (P) and one recessive (p) allele, so it's heterozygous. So "Pp" matches with 1. Heterozygous.

Step3: Analyze "P"

In genetics, a dominant allele is often represented by a capital letter. So "P" is a dominant allele, matches with 3. Dominant.

Step4: Analyze "p"

A recessive allele is often represented by a lowercase letter. So "p" is a recessive allele, matches with 5. Recessive.
(Note: The terms "Genotype" (2) and "Phenotype" (6) are not used here as the items to match are about alleles or allele combinations related to zygosity and dominance/recessiveness. If there were items like "the genetic makeup of an organism" (would be Genotype) or "the physical appearance of an organism" (would be Phenotype), they would be used, but in this matching set with the given items, we use the above matches.)

Answer:

"PP and pp" - 4. Homozygous
"Pp" - 1. Heterozygous
"P" - 3. Dominant
"p" - 5. Recessive
