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.

haploid cells;

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
