You perform a dihybrid cross of plants. The first trait is
flower color. “A” is the dominant allele and causes red petals and
“a” is the recessive allele and causes white petals. Stem length is
the second trait. “L” is the dominant allele and causes a long stem
and “l” is the recessive allele and causes short stems. You cross a
Red Long plant that is heterozygous for both traits with a Red
Short plant that is heterozygous for color....
