Meiosis

The process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell.

A cell that contains one set of chromosomes

• haploid

• diploid

• triploid

• tetrad

Chromosomes of approximately the same shape, size, and genes. One is inherited from the organism's mother; the other is inherited from the organism's father.

• centromere

• sister chromatids

The process in which homologous chromosomes exchange portions of their chromatids during prophase I of meiosis

• fertilization

• crossing over

• nondisjunction

• karyotype

The principle that genes for different traits can segregate independently during meiosis (the formation of gametes)

• independent assortment

• fertilization

• zygote

• nondisjunction

The process in sexual reproduction in which male and female reproductive cells join to form a new cell

• crossing over

• independent combination

• nondisjunction

• fertilization

A fertilized egg cell

• somatic cell

• gamete

• zygote

• haploid cell

The X and Y chromosomes of a human karyotype are

• autosomes

• sex chromosomes

• diploid

• haploid
