Sexual vs. Asexual Reproduction Circle

Asexual Reproduction When humans reproduce, there are two parents involved. DNA must be passed from both the ...

Sexual Reproduction and Inherited Traits

You can investigate this question by considering an imaginary animal called the unimonster. Suppose this animal has only one pair of chromosomes. Chromosomes carry genes, which control ...

Reproduction – sexual differentiation
