Question

A tall pea plant with Axial position of flower on the stem is fertilized with dwarf pea plant with terminal position of flower on the stem. find the possibilities of offspring produced upto second generation.

Answer 1

Answer:

TTAa x ttaa

Explanation:

The alleles for tallness (T) and axial flower (A) are dominant over that of dwarfism (t) and terminal flower (a) respectively. Since recessive traits are exhibited in homozygous genotypes only, the genotype of a dwarf parent with the terminal flower is "ttaa". To have both axial and terminal flowers in the progeny, the dominant parent should be heterozygous to allow the expression of a recessive allele in the next generation. This makes the genotype of tall plant with axial flower "TTAa".
