Consider the cross AaBbCcddEe X AABBccDDEe. If these 5 allele pairs all assort independently, then the probability that any individual offspring will have the genotype AaBBCcDdEE is 1 out of???
I don't know where to start. It is not homework, it is a practice problem that I am having troubles with.
To determine the probability of getting the genotype AaBBCcDdEE in the offspring, we need to consider the probability of each allele pairing occurring.
Cross: AaBbCcddEe X AABBccDDEe
Step 1: Determine the probabilities for each allele pairing.
First, let's consider each allele pair independently.
Aa: The individual with genotype Aa can only contribute the 'A' allele.
Probability of getting 'A' allele from Aa: 1 (since there is no other option)
Bb: The individual with genotype Bb can contribute either 'B' or 'b' allele.
Probability of getting 'B' allele from Bb: 1/2
Probability of getting 'b' allele from Bb: 1/2
Cc: The individual with genotype Cc can contribute either 'C' or 'c' allele.
Probability of getting 'C' allele from Cc: 1/2
Probability of getting 'c' allele from Cc: 1/2
dd: The individual with genotype dd has two 'd' alleles, so it can only contribute the 'd' allele.
Probability of getting 'd' allele from dd: 1 (since there is no other option)
Ee: The individual with genotype Ee can contribute either 'E' or 'e' allele.
Probability of getting 'E' allele from Ee: 1/2
Probability of getting 'e' allele from Ee: 1/2
Step 2: Calculate the overall probability of getting the desired genotype.
Since each allele pair is independent, we can multiply the probabilities of each allele pairing to obtain the overall probability.
Probability of getting AaBBCcDdEE = Probability(A allele) x Probability(B allele) x Probability(C allele) x Probability(d allele) x Probability(E allele)
= 1 x 1/2 x 1/2 x 1 x 1/2
= 1/4
Therefore, the probability of any individual offspring having the genotype AaBBCcDdEE is 1 out of 4 (1/4).
To determine the probability of offspring having the genotype AaBBCcDdEE, we need to consider the independent assortment of alleles from each of the five allele pairs.
In a cross between AaBbCcddEe and AABBccDDEe, the different alleles are paired as follows:
AaBbCcddEe x AABBccDDEe
We have five allele pairs: Aa x AA, Bb x BB, Cc x cc, dd x DD, and Ee x Ee.
Each allele pair can assort independently, meaning that the alleles from each pair can segregate randomly and combine in any possible combination in the offspring.
To determine the probability of a specific genotype (AaBBCcDdEE), we need to consider the probability of getting each of the necessary alleles for that genotype. Let's break it down:
1) Aa: The probability of getting 'A' from Aa is 1, as 'A' is always present.
2) Bb: The probability of getting 'B' from Bb is 1, as 'B' is always present.
3) Cc: The probability of getting 'C' from Cc is 1, as 'C' is always present.
4) Dd: The probability of getting 'D' from Dd is 1, as 'D' is always present.
5) EE: The probability of getting 'E' from Ee is 0.5, as 'E' can be obtained from either parent (Ee x EE).
To calculate the overall probability, we multiply the probabilities for each allele pair:
1 x 1 x 1 x 1 x 0.5 = 0.5
Therefore, the probability that any individual offspring will have the genotype AaBBCcDdEE is 0.5 or 1 out of 2.
