NGSS.HS-LS3-2

Cell condition in which only one of each type of chromosome is present.

• haploid
• diploid
• monoploid
• multiploid

Set of chromosomes, one inherited from either parent that have the same genetic loci and pair up during meiosis.

• homologous chromosomes
• sister chromatids
• multiple alleles

Alleles of unlinked genes segregate independently of each other during meiosis so that the gametes could contain all possible combinations of alleles.

• independent assortment
• law of segregation
• mitotic division

Diagram showing chromosomes arranged by pairs according to their size.

• karyotype
• pedigree
