In a certain species, the allele for tall plants (T) is dominant over the allele for short plants (t). If a tall plant (Tt) is crossed with a short plant (tt), what is the expected genotypic ratio of the offspring?
1:1
3:1
1:2:1
2:1
The cross Tt x tt results in a genotypic ratio of 1 Tt (tall) to 1 tt (short), which is 1:1.
