Answer:
As we saw last time, if we start with true-breeding parents (one homozygous dominant, one homozygous recessive), all of the F1 progeny will be heterozygous and show the dominant phenotype, and then these will give rise to a 3:1 ratio of phenotypes in the F2 generation in a monohybrid cross, and to a 9:3:3:1 ratio of ...Jul 9, 2005

Answer:
All members of the F1 generation are heterozygous and share the same dominant phenotype (2), while the F2 generation exhibits a 6:2 ratio of dominant to recessive phenotypes (3).
