Question

a female fern plant is heterozygous for a gene related to photosynthesis (pp). select all of the different possible genotypes that her eggs could possess. correct answer(s) p + pp + pp + pp + pp + incorrect answer(s)

Explanation:

Step1: Apply Mendel's law of segregation

According to Mendel's law of segregation, during gamete formation (in this case, egg formation), the two alleles of a gene separate from each other. The plant has a genotype \(Pp\).

Step2: Determine possible gamete genotypes

When the \(Pp\) plant forms eggs (gametes), each egg will receive either the \(P\) allele or the \(p\) allele. Genotypes like \(PP\), \(Pp\), and \(pp\) are not possible for a single - gamete (egg) from a \(Pp\) parent. A gamete has a haploid set of chromosomes, so it can only have one allele of a gene.

Answer:

\(P\), \(p\)
