What are the characteristics of hybrid apricots obtained as a result of pollination of red-fruited (A) plants

What are the characteristics of hybrid apricots obtained as a result of pollination of red-fruited (A) plants of normal growth (B) with pollen of yellow-fruited dwarf plants? What result will the further crossing of such hybrids give?

Apparently, the problem implies that apricots of normal growth with red fruits are representatives of the pure line – homozygotes AABB. Such apricots produce sex cells of the same type – AB.

Dwarf apricots with a yellow fruit will have a dihomozygous aabb genotype, because both traits are classified as recessive and can be realized in the phenotype only if the individual is homozygous for recessive genes.

Apricots aabb also produce one type of germ cells, ab.

All F1 offspring are hybrid apricots of normal growth with red AaBb fruits. These plants, in turn, produce sex cells of four types – ab, AB, aB, Ab.

When hybrid apricots are crossed with each other, F2 offspring will be obtained, including the following options:

apricots that form red fruits and have normal growth (4 AaBb, AABB, 2AaBB, 2AABb) – 56.25%;

apricots that form red fruits and have dwarf growth (2Aabb, AA bb) – 18.75%;

apricots that form yellow fruits and have a dwarf growth (aabb) – 6.25%;

apricots that form yellow fruits and have normal growth (aaBB, 2aaBb) – 18.75%.
