In a certain species, the allele for tall plants (T) is dominant over the allele for short plants (t). If two heterozygous tall plants (Tt) are crossed, what is the expected phenotypic ratio of the offspring?
1:2:1
3:1
9:3:3:1
1:1
The expected phenotypic ratio from Tt x Tt is 3 tall: 1 short, which is a 3:1 ratio.
