Question

Garden pea plant heterozygous for dominant trait tallness is self and 1200 seeds are obtained how many seedlings obtained from sajjid will have a parent genotypes ​

Answer 1

600 seeds

Step-by-step explanation:

The allele for tallness- T

The allele for dwarfness- t

heterozygous genotype for tallness- Tt

When heterozygous genotype are crosses

Tt x Tt

T t

T TT Tt

t Tt tt

We get

TT (tall plants)- 1/4

Tt (tall plants with hetrozygous genotype)- 2/4

tt (short plants)- 1/4

Now,

2/4 of 1200 seeds will be 600

Thus, 600 seeds will have the same genotype as of parents.
