Answer 1

B

Step-by-step explanation:

Answer 2

Answer: the correct answer is 25%

T is the allele for tall plant, which is dominant trait. 't' is the allele for dwarf plant, which is a recessive trait.

Genotypes of the parent plants are- Tt and Tt. When they are crossed, there are 25% chances of producing tt offsprings. Refer the punnett square for this.

% of Offsprings with tt genotype =
`(1)/(4) * 100`

= 25%
