Question

a homozygous round seeded plant is crossed with a heterozygous round seeded plant .find out the offspring
​

Answer 1

The results show that 50% of the offspring will be heterozygous round whereas 50% will be homozygous round.

Explanation:

• Let the alleles for homozygous round seeded plant be represented by RR.
• Let the alleles for heterozygous round seeded plant be represented by Rr.
• Now, lets make a punnet square

            R         r

R       RR       Rr

R        RR      Rr

• The results show that 50% of the offspring will be heterozygous round whereas 50% will be homozygous round. The genotypic ration will be 1:1

Answer 2

Answer:

50% of the offspring will be heterozygous round whereas 50% will be homozygous round.

Explanation:

Let the alleles for homozygous round seeded plant be denoted by RR.

Let the alleles for heterozygous round seeded plant be denoted by Rr.

Now, make a punnet square

                      R         r

            R       RR       Rr

            R       RR      Rr

Here, Number of heterozygous round offspring = 2

Number of  homozygous round offspring = 2

Genotypic ratio = 2/2 = 1:1

Heterozygous round offspring = 50% of total offspring

Homozygous round offspring = 50% of total offspring

It is seen  that 50% of the offspring will be heterozygous round whereas 50% will be homozygous round.

The genotypic ratio will be 1:1
