Solution

The correct option is D YR, yr
The parents of Mendel’s dihybrid cross were homozygous for both the characters. One parent having the genotype YYRR was crossed with the other parent of genotype yyrr. Hence, they produced two type of gametes, YR from the homozygous parent with the dominant trait and yr from the homozygous parent with the recessive trait.

Question 5
If a round, green-seeded pea plant (RRyy) is crossed with wrinkled, yellow-seeded pea plant (rrYY), the seeds produced in F1 generation are

(a) round and yellow
(b) round and green
(c) wrinkled and green
(d) wrinkled and yellow
( Round-R, Green-y, Wrinkled-r, Yellow-Y)

Mendel first crossed pure-bred pea plants having round -yellow seeds with pure-bred pea plants having wrinkled -green seeds and found that only round- yellow seeds were produced in the $F_{1}$ generation. When $F_{1}$ generation pea plants having round-yellow seeds were cross-bred by self-pollination, then peas having round-yellow seeds, round green seeds, wrinkled-yellow seeds and wrinkled -green seeds were produced. Mendel collected a total of 2160 seeds.

(a) What will be the number of (i) round green seeds (ii) wrinkled green seeds (iii) round yellow seeds, and (iv) wrinkled-yellow seeds?

(b) Which 'ratio' as established by Mendel have you made use of in answering the part (a) above?
