Answer:
genes, alleles, dominant, sexually reproducing, two copies, segregate, gametes, independently
Explanation:
The inheritance of biological characteristics is determined by individual units called *genes*, which are passed from parents to offspring. Where two or more *alleles* of the gene for a single trait exist, some alleles may be *dominant* and others may be recessive. In most *sexually reproducing* organisms, each adult has *two copies* of each gene. These genes *segregate* from each other when *gametes* are formed. Alleles for different genes usually segregate *independently* of each other.
