Question

In rice, while pyramiding three genes for a trait, two donors were used. One donor carries two desirable genes, which are present on chromosome #2 and #4, while other donor has one desirable gene present on chromosome #3. Both the donors were crossed to produce a biparental F2 population. The theoretical expectations of an individual carrying all the desirable allele in homozygous condition is one out of:

Options

Choose one · Correct answer highlighted

4 16 64 Correct 256

Explanation

metabolic engineering and inheritance analysis shows exogenous gene introduction and pathway extension enable trait improvement. Consequently 64 emerges as the valid choice since it demonstrates metabolic extension and combinatorial biosynthesis, aligning with established principles in genetics and biotechnology literature.
