Answer
When two genes are unlinked, they assort independently during gamete formation. This means the inheritance of one gene does not affect the inheritance of another.
Step 2
B. the genes are close together on the same chromosome.

Answer
This statement is incorrect. Unlinked genes are not close together on the same chromosome; instead, they are located on different chromosomes or far apart on the same chromosome.
Step 3
C. there is recombination between the two genes during meiosis.

Answer
Correct. Unlinked genes are subject to recombination during meiosis, meaning they can be inherited independently due to the random assortment of chromosomes.
Step 4
D. particular combinations of alleles of these genes are always inherited together.

Answer
This statement is incorrect for unlinked genes. If genes are unlinked, different combinations of alleles can occur, as these genes assort independently.
