In pea plants, the allele for tallness is dominant (T) to the allele for shortness (t). A pea plant that is tall (TT) is mated with another pea plant that is short (tt). Which of the following is correct about their offspring? (Do a Punnett square if needed!) *
1. Half (50%) of the offspring will have the dominant allele
2. All of the offspring will be short
3. All of the offspring will be tall
4. Half (50%) of the offspring will carry the recessive allele
