Segregation of alleles during meiosis: • When the F1 plants produce gametes (sex cells) and self-pollinate, the two alleles for the same gene separate from each other so that each gamete carries only one copy of each gene. • Remember, gametes are haploid. In the example, we use “T” to represent the ...
