Tall pea plants are dominant over short pea plants. If there are 200 short plants in the F2 generation from a cross that followed Mendel’s methods, about how many plants will be tall in that generation?

The correct answer is 600 tall plants.

Explanation:

When there is crossing in two true-breeding plants produce hybrid offspring or heterozygous offspring with the character of dominant alleles and known as F1 generation.

Offspring in the F1 generation would have the genotype of Tt and would have the phenotype of being tall due to the dominancy of the tall allele. Cross in between two F1 offspring to produce F2 can be represented by the  punnet square:

      T        t

T    TT     Tt

t     Tt       tt

TT - tall

Tt - tall 

tt -  short

The punnet square shows that F2 generation have 3;1 phenotypic ratio in between tall and short plant. The 200 short plants in the questions would be 25% of 800 or 1:4. Take the 200 away from 800 and you get 600 that would be tall.

Thus, the correct answer is 600 tall plants.

typically, most spiders possess eight eyes. however, others have as many as 12, and some don't have any. these eyes are for detecting light from dark, deciphering shapes and for gathering their prey.
