Detailed explanation-1: -Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio. Or, about 75% of the offspring will be purple.
Detailed explanation-2: -Answer and Explanation: In this situation, every offspring produced from this cross with be a heterozygote (Pp), and because purple is dominant to white, all the offspring will be purple. Therefore, the probability of an offspring having white flowers is zero.
Detailed explanation-3: -Answer and Explanation: If we cross two heterozygous purple plants, the probability of purple offspring would be 75%.
Detailed explanation-4: -The probability that one of their offspring will have white flowers is 1/4 .
Detailed explanation-5: -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.
