When egg and sperm combine.

• meiosis

• fertilization

• mitosis

• gamete

A pair of chromosomes that carry the same traits, but maybe different alleles.

• holy moly chromosomes

• homozygous chromosomes

• hunky-dory chromosomes

• homologous chromosomes

A cell with 23 chromosomes.

• neuron of the brain

• gamete

• red blood cell

• skin cell

One version of a trait, like brown hair, or green eyes.

• allele

• homologous chromosome

• dad

• both

• It is decided randomly from all of the ancestors.

How many chromosomes does a human gamete have?

• 2

• 92

• 46

• 23

How do the cells know to take one of each pair of homologous chromosomes to make gametes?

• They text each other first to decide who gets what.

• The new cells get random chromosomes put into them.

• The cell membrane (skin of the cell) grabs one of each with its lipid bilayer and moves it into place.

• The homologous chromosome pairs line up in the middle of the cell and move away from each other into two new cells.
