Red is dominant (R). Complete this Punnett square for a homozygous yellow plant crossed with a heterozygous red plant. With yellow (r) as a recessive allele in plants and red as a dominant (R), what would the percentage of each type be if a homozygous yellow plant is crossed with a heterozygous red plant? ____% of the offspring would be homozygous yellow (rr) ____% of the offspring would be heterozygous red (Rr) ____% of the offspring would be homozygous red (RR) Yellow (r) is a recessive allele in plants. Red is dominant (R). Complete this Punnett square to show what would result if two heterozygous red plants were bred.
