Explanation:
In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is dominant to the allele for white flower colour. What is the genotype of a short plant produced from a cross between a true-breeding purple flowered pea plant and a true-breeding white flowered pea plant? *
1.TTPP
2.ttpp
3.ttPP
4.ttPp
5.TtPp
Answer:
The correct answer is - 4. ttPp
Explanation:
Given - tall is dominant over short pea plant
let assume T is dominant and t is short which is recessive
Similarly, P for dominant purple flower and p for white flower
The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:
P P
p Pp Pp
p Pp Pp
This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant
Thus, the correct answer is ttPp
