Pigmentation in moth is the example of the maternal effect in which the cytoplasm and genotype of the mother affect the phenotype of the progeny as mother genotype is a+/a that’s why all the progenies will be pigmented at larval stages

Explanation:
Pigmentation in moths is maternally affected, which means that the pigmentation of the offspring is determined by the genotype of the mother. In this case, the mother has a genotype of a/a, meaning that she is unpigmented.
Genotypes:
- Mother: a/a
- Father: aa
Genetic Cross:
When we cross the mother (a/a) with the father (aa), we get the following possibilities for the progeny:
- Offspring 1: a/a (unpigmented)
- Offspring 2: a/a (unpigmented)
- Offspring 3: a/a (unpigmented)
- Offspring 4: a/a (unpigmented)
Explanation:
Since pigmentation in moths is maternally affected, the genotype of the mother (a/a) determines the pigmentation of the offspring. In this case, all the offspring will have the genotype a/a, which means they will all be unpigmented at the larval stage.
Therefore, the correct answer is option B: All pigmented at the larval stage.
Key Points:
- Pigmentation in moths is maternally affected.
- The genotype of the mother determines the pigmentation of the offspring.
- The mother has a genotype of a/a, meaning she is unpigmented.
- The father has a genotype of aa, meaning he is pigmented.
- When the mother (a/a) is crossed with the father (aa), all the offspring will have the genotype a/a and be unpigmented at the larval stage.
