Question

The punnett square shown below represents the pattern of inheritance in a dihybrid cross when yellow seed colour (Y) is dominant over white (y) and round shape (R) is dominant over wrinkled (r) seeds:

A plant of type 'H' will produce seeds with genotypes identical to the seeds produced by the plants of:

• A. Type M
• B. Type U
• C. Type S
• D. Type N

Answer 1

The correct option is D Type N

Type 'H' will have genotype - YyRR.

Type 'N' will have the genotype - YyRR.
Since, both 'H' and 'N' have same genotype, they can have genotypically identical offsprings.
