Solution By Steps

Step 1: Understand the terms

Hemizygous: Having a single copy of a gene, typically on a sex chromosome in an organism with two different sex chromosomes (e.g., X and Y in humans).

Homozygous: Having two identical alleles (versions) of a gene, one inherited from each parent.

Heterozygous: Having two different alleles of a gene, one inherited from each parent.

Step 2: Analyze the genotype "PP"

The genotype โ€œPPโ€ represents two identical alleles, both being โ€œPโ€.

Step 3: Determine the correct description

Since the genotype โ€œPPโ€ has two identical alleles, it is considered homozygous.

Final Answer

The genotype โ€œPPโ€ can best be described as homozygous.

The concept of homozygous and heterozygous genotypes is fundamental in genetics and inheritance patterns. A homozygous genotype, like โ€œPPโ€, means that an organism has two identical alleles for a particular gene, resulting in a consistent expression of the associated trait. This is in contrast to a heterozygous genotype, where the two alleles are different, potentially leading to different phenotypic expressions or intermediate traits. Understanding these concepts is crucial for predicting and analyzing genetic inheritance, gene expression, and the manifestation of traits in organisms.
