NGSS.HS-LS1-4

Any chromosome other than a sex chromosome.

• haploid

• gene

• autosome

• zygote

A chromosome that determines whether an organism is male of female.

• sex chromosome

• tetrad

• autosome

• zygote

Chromosomes that are the same size and shape but contain variations of genetic information. One is a maternal chromosome and one is paternal.

• homologous chromosomes (pair)

• autosomes

• zygotes

• tetrads

A cell that contains two complete sets of chromosomes, one from each parent.

• diploid

• haploid

• centromere

• gene

A cell that contains one complete set of chromosomes not in pairs.

• diploid

• haploid

• centromere

• gene

The series of events, including duplication of DNA, leading to the division of a cell into two daughter cells.

• Cell Cycle

• crossing over

• meiosis

• sexual reproduction
