Question

question 3
an individual who is homozygous
○ expresses the recessive trait
○ carries two copies of the same allele for a gene
○ expresses the dominant trait
○ carries two different alleles for a gene

Explanation:

A homozygous individual has two identical alleles for a particular gene. For example, in pea plants, if the gene for flower color has alleles \(P\) (purple - dominant) and \(p\) (white - recessive), a homozygous individual could be \(PP\) (homozygous dominant) or \(pp\) (homozygous recessive). The first option is incorrect because a homozygous individual could be dominant (\(PP\)) or recessive (\(pp\)). The third option is incorrect for the same reason (it could be recessive). The fourth option describes a heterozygous individual (e.g., \(Pp\)). The second option is correct as it aligns with the definition of homozygous (two copies of the same allele for a gene).

Answer:

carries two copies of the same allele for a gene
