Segments of DNA that code for the production of specific proteins are called -
genes
alleles
chromosomes
zygotes
Different versions of the same gene are called -
(a)
What is a gamete? (Check all that apply)
sex cell
sperm
egg
body cell
The chromosomes that determine your biological sex (for example, X and Y)
Sex chromosomes
Somatic cells
Homologous chromosomes
Sex cells (gametes)
This type of cell division produces gametes and only occurs in the ovaries and testes in humans.
Mitosis
Meiosis
The random lining-up of homologous pairs at the cell’s middle is called -
crossing over
homologous chromosomes
independent assortment
mitosis
This type of cell division occurs in your muscles, bones, lungs, liver, and heart, and it produces somatic (body) cells.
(a)
The complete set of genes in an organism is called a -
gamete
genome
chromosome
zygote
What are somatic cells?
Somatic cells are cells that make up all of the body except for the gametes.
Somatic cells are cells that develop into gametes.
Somatic cells are segments of DNA that code for the production of specific proteins.
Somatic cells are structures located inside the nucleus of animal and plant cells.

Two cells (exact copies) are produced in meiosis.
True
False
Versions of a gene, called alleles, may arise through mutation.
True
False
The cells in a person's gametes have the same DNA as the cells in their skin and liver cells.
True
False
Gametes are the cells that combine the alleles from the mother and father to create the genome for the zygote.
True
