Meiosis

specialized cell involved in sexual reproduction

• gamete

• meiosis

• haploid

• genetic variation

having a single set of unpaired chromosomes

• gamete

• meiosis

• haploid

• diploid

a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

• genetic variation

• meiosis

• mitosis

• diploid

a reproductive process that involves two parents that combine their genetic material to produce a new organism, which differs from both parents

• asexual reproduction

• zygote

• sexual reproduction

• mitosis

exchange of genetic material between homologous chromosomes during prophase I of meiosis

• tetrad

• crossing over

• sexual reproduction

• sister chromatids

containing two complete sets of chromosomes, one from each parent.

• diploid

• prophase I

• haploid

• sister chromatids

heritable variations in a population.

• diploid

• tetrad

• homologous

• genetic variation

term used to refer to chromosomes that each have a corresponding chromosome with similar genes in the same location.

• homologous

• centromere

• synapsis

• matching

any heritable difference between individuals of the same species.

• changes

• haploid

• crossing over

• variation

the chromosomes become visible, and the nucleus dissolves. Homologous chromosomes pair up to form tetrads, crossing over occurs

• metaphase I

• prophase II

• prophase I

• anaphase II
