Detailed explanation-1: -100 % Explanation: In the given question, the allele for dominant trait is dominant to white flower. Then all the progeny will be white therefore 100% is the correct answer.

Detailed explanation-2: -Here, it has been given that purple flower color is dominant over the white flower color. Hence, the flower color of a plant that is heterozygous for this trait will be purple. Let P be the dominant allele and p be the recessive allele. i.e, 3/4 or 75% of the offsprings will have purple-colored flowers.

Detailed explanation-3: -The probability that one of their offspring will have white flowers is 1/4 .

Detailed explanation-4: -When a heterozygous purple flower (Rr) is crossed with a recessive white flower (rr), the progeny obtained are with the genotype (Rr), (Rr), (rr) and (rr). So, 50% of the progeny are with purple flowers (Rr) and 50% are with white flowers (rr).

Detailed explanation-5: -A pea plant with purple flowers was crossed with white flowers, producing 50 plants with only purple flowers. On selfing, these plants produced 482 plants with purple flowers and 162 with white flowers.
