The correct answer is D. the offspring can be tall or short
In a given cross, F1 pea plants are hybrid tall or heterozygous tall (Tt). If F1 plants are allowed to self-pollinate, as a result tall and short pea plants are formed in the ratio 3:1 respectively. This result obeys Mendel’s law of segregation which states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.
