two
An individual can acquire only ___ allele(s) per trait, even if multiple alleles are present in the population.
1. allowing plants to self-cross to ensure they are true- breeding. 2. reciprocal crosses between true-breeding varieties. 3. allowing hybrid offspring to self-fertilize
Place the three stages of Mendel's in the correct order.
1. Each individual receives one copy of each gene from each parent. 2. parents transmit factors to offspring 3. the presence of an allele doesn't ensure that it will be expressed. 4. alternative forms of genes are called alleles
