Asexual reproduction, but not sexual reproduction, is characteristic of plants and fungi.
In sexual reproduction, individuals transmit 50% of their genes to each of their offspring.
In asexual reproduction, offspring are produced by fertilization without meiosis.
Sexual reproduction requires that parents be diploid.
Asexual reproduction produces only haploid offspring.

Are both present in every somatic cell of males and females alike.
Are of approximately equal size and number of genes.
Are almost entirely homologous, despite their different names
Include genes that determine an individual's sex
Include only genes that govern sex determination.
The species is diploid with 32 chromosomes per cell.
The species has 16 sets of chromosomes per cell.
Each cell has eight homologous pairs.
During the S phase of the cell cycle there will be 32 separate chromosomes.
A gamete from this species has four chromosomes.
In humans, each of the 22 maternal autosomes has a homologous paternal chromosome.
In humans, the 23rd pair, the sex chromosomes, determines whether the person is female (XX) or male (XY).
Single, haploid (n) sets of chromosomes in ovum and sperm unite during fertilization, forming a diploid (2n), single-celled zygote.
At sexual maturity, ovaries and testes produce diploid gametes by meiosis.
Sexual life cycles differ with respect to the relative timing of meiosis and fertilization.
