Chapter 10.2, Problem 3CC
Summary Introduction
To determine:
The haploid and diploid number in a pea plant speciesin which each sperm contains seven chromosomes.
Introduction:
Ploidy refers to the number of sets of chromosome present in a cell. Haploid refers to one set of chromosome (n), while diploid cells contain two set of chromosomes (2n).

This quirk of genetics results from the fact that bees have haplodiploid sex determination, in which females are diploid, with a mother and a father, but males are haploid, developing from unfertilized eggs. Because males are haploid, they produce sperm by mitosis. Explainwhy haplodiploid sex determination causes females to be more closely related to their sisters than to their offspring.arrow_forward
