Normal growth in oats dominates gigantism, and early maturity dominates late maturity. What phenotype can the hybrids

Normal growth in oats dominates gigantism, and early maturity dominates late maturity. What phenotype can the hybrids obtained from crossing a diheterozygous plant with a plant heterozygous for the first and homozygous for the second trait have?

Let’s designate the dominant and recessive alleles of genes: A – normal growth, a – gigantism, B – early maturity, b – late maturity.
a) If the genotype of the paternal plant is AaBB, then in the offspring the plants of normal growth are early maturing and giant late maturing in a ratio of 3: 1;
b) if the genotype of the parent plant is Aabb, then in the offspring the plants of normal growth are early maturing, normal growth is late maturing, giant early maturing and giant late maturing in a ratio of 1: 1: 1: 1.
