Given the parent genotype AaBbCCDDEe, what is the probability of each of these gametes forming?
a) ABCDE
b) either ABCDE or abCDE
a) Pr=1/2 *1/2*1*1*1/2
b) pr=1*1*1*1*1/2
just multiply the pr of each outcome given the genome.
What is the Pr?
No I’m sorry Would the answer for a) be 1/8 and for b) be 1/2?
To determine the probability of a specific gamete forming, we need to consider the principles of Mendelian genetics and understand how gametes are formed.
In this case, the parent genotype is AaBbCCDDEe. Each gene locus, represented by a letter, has two alleles, one from each parent. The uppercase letters represent dominant alleles, and the lowercase letters represent recessive alleles.
Given this information, let's calculate the probability of each of these gametes forming:
a) ABCDE
To calculate the probability of each allele pairing independently, we multiply the probability of each allele. In this case, the first allele for each gene locus can be either uppercase or lowercase with equal probability.
Probability of A or a = 1/2
Probability of B or b = 1/2
Probability of C = 1 (since there is no alternative allele)
Probability of D = 1 (since there is no alternative allele)
Probability of E or e = 1/2
To calculate the probability of the combination ABCDE forming, we multiply the probabilities together:
Probability(ABCDE) = Probability(A) × Probability(B) × Probability(C) × Probability(D) × Probability(E)
= (1/2) × (1/2) × 1 × 1 × (1/2)
= 1/8
Therefore, the probability of the gamete ABCDE forming is 1/8.
b) Either ABCDE or abCDE
To calculate the probability of either ABCDE or abCDE forming, we need to consider the probability of each option separately and then add them together.
Probability(ABCDE) = 1/8 (as calculated in part a)
Probability(abCDE) = Probability(a) × Probability(b) × Probability(C) × Probability(D) × Probability(E)
= (1/2) × (1/2) × 1 × 1 × (1/2)
= 1/8
To calculate the probability of either ABCDE or abCDE forming, we add the probabilities together:
Probability(ABCDE or abCDE) = Probability(ABCDE) + Probability(abCDE)
= 1/8 + 1/8
= 2/8
= 1/4
Therefore, the probability of either ABCDE or abCDE forming is 1/4.
