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

600 seeds

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.

answer; i believe the answer is (polygenic inheritance;
