Suppose a plant with long striped fruit is crossed with a plant heterozygous for both of these characters. What phenotypes would this cross produce and in what ratios? Phenotypes = 1/2 short/green 1/2 long/green= 1:1 ratio Phenotypes = 1/4 short/green 1/4 short/striped 1/4 long/green 1/4 long/striped = 1:1:1:1 ratio Phenotypes = 3/4 short/green 1/4 long/green = 3:1 ratio Phenotypes = All short/green = 1:0 ratio3. Short-tailed pup distribution. In mice, the dominant T allele results in a short tail. Homozygous T/T genotype is lethal, which means mouse embryos with this genotype die before they are born.
