In the life cycle of sexual reproducers, what is the ploidy of organisms that have two sets of chromosomes?
A
Triploid
B
Tetraploid
C
Haploid
D
Diploid
Verified step by step guidance1
Understand the concept of ploidy: Ploidy refers to the number of sets of chromosomes in a cell. Each set is denoted by 'n'.
Identify the ploidy levels: Haploid (1n) means one set of chromosomes, Diploid (2n) means two sets, Triploid (3n) means three sets, and Tetraploid (4n) means four sets.
Recognize that in sexual reproduction, organisms typically have a diploid stage where they possess two sets of chromosomes, one from each parent.
Recall that during fertilization, two haploid gametes (sperm and egg) combine to form a diploid zygote, which then develops into a diploid organism.
Conclude that organisms with two sets of chromosomes are diploid, as they have one set from each parent, making the correct answer 'Diploid'.
