PPT-Meiosis Each organism must inherit a single copy of every gene from each of its “parents.”

Gametes are formed by a process that separates the two sets of genes so that each gamete ends up with just one set Chromosome Number All organisms have different numbers of chromosomes A body cell in an adult fruit fly has 8 chromosomes 4 from the fruit flys male parent and 4 from its female parent. EQ:. What is the importance of meiosis in providing genetic variation?. . SPECIALIZED CELLS. You have many specialized cells in your body that can be divided into two groups. . 1. . .
