6. What does the law of segregation state?
F. The two alleles for a gene separate when
gametes are formed.
G. A species can have a variety of different
alleles that code for a single characteristic.
H. The alleles of different genes separate
independently from one another during gamete
formation.
J. Populations of a single species divided
geographically will change over time to form two
separate species.

relationship between chromosomes and genes.
Student paragraphs should be well-formed and free of
grammatical and scientific errors. Genes are found on
chromosomes.
