Lesson Overview
... When each parent, or F1 adult, produces gametes, the alleles for each gene segregate from one another, so that each gamete carries only one allele for each gene. In other words: You have two alleles for each trait (one from each of your parents). You will give each sex cell 1 of those alleles. ...
