Question

what is the name for the system in which haploid males are produced from unfertilized eggs and diploid females from fertilized eggs? a) triploidy b) polyploidy c) haplodiploidy d) monoploidy

Explanation:

To solve this, we analyze each option:

• Option A (triploidy): Involves having three sets of chromosomes, not related to sex determination from fertilized/unfertilized eggs.
• Option B (polyploidy): Refers to having more than two sets of chromosomes, not about the described sex - determination system.
• Option C (haplodiploidy): By definition, in this system, males develop from unfertilized (haploid) eggs and females develop from fertilized (diploid) eggs, which matches the description in the question.
• Option D (monoploidy): Means having a single set of chromosomes, and is not related to the given sex - determination mechanism.

Answer:

C) haplodiploidy
