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:

Q.

Q. The figure 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 trait combination identical to the seeds produced by the plants of ____.

Q. Match column I with column II and choose the correct option.
$\begin{array}{cccc}& \text{Column I}& & \text{Column II}\\ \text{i}& \text{Seed colour}& \text{a}& \text{Round dominant over wrinkled}\\ \text{ii}& \text{Pod colour}& \text{b}& \text{Yellow dominant over green}\\ \text{iii}& \text{Pod shape}& \text{c}& \text{Green dominant over yellow}\\ \text{iv}& \text{Seed shape}& \text{d}& \text{Inflated dominant over constricted}\end{array}$

Q. The genotype of ${\text{F}}_1$ hybrids produced by crossing pure yellow round seeded plant (YR) with pure green wrinkled seeded (yr) plant is ___.

Q. The mean lives of a radioactive substance are $1200\text{yr}$ and $600\text{yr}$ for $\alpha -\text{emission}$ and $\beta -\text{emission}$ respectively. In $56\times n\text{yr}$ three fourth of the sample decays by simultaneous $\alpha -\text{emission}$ and $\beta -\text{emission}$ respectively. The value of $n$ is (integer only)
