Locus Accurate Answer - Location of gene on chromosome.
Gamete Accurate Answer - Haploid sex cells that are used for
reproduction.
Male Gamete Accurate Answer - Haploid cells.
Female Gamete Accurate Answer - Haploid cells.
Asexual Reproduction Accurate Answer - One parent cell, cloning.
Sexual Reproduction Accurate Answer - Two parent cells, variation.
What is a chromosome? Accurate Answer - A cellular structure
carrying genetic material, found in the nucleus of eukaryotic cells
How many chromosomes are in human cells? Accurate Answer - 46
Which type of reproduction will result in genetically identical offspring?
Accurate Answer - Asexual reproduction.
What is a somatic cell? Accurate Answer - Any cell other than those
involved in gamete formation.

How does a somatic cell compare to a gamete in terms of chromosome
number? Accurate Answer - Unlike somatic cells, gametes contain a

Accurate Answer - The size of the chromosomes, the position of the

- Homologous chromosomes are a pair of chromosomes of the same length,
centromere position, and staining pattern.
Haploid Cell Accurate Answer - Cells that have only one of each
homologous pair.
