tell me if im wrong :/
Answer:
A laboratory mouse homozygous for a specific allele is mated to a wild mouse that is heterozygous for that allele. One of the heterozygous individuals resulting from this cross is mated back to the wild field mouse parent. What proportion of the offspring will have the same genotype as the original laboratory mouse?
RR x Rr= RR, Rr, RR, and Rr 4:0 genotype
Rr x Rr= RR, Rr, Rr and rr 2:2 50:50%
50% of the offspring will have the same genotype as the original laboratory mouse
Explanation:
First, we need to solve for the common ratio from the data given by using the equation.
a(n) = a(1) r^(n-1)
1024 = 4 r^(9-1)
256 = r^8
r = 256^(1/8)
r = 2
Then, we can find the sum by the expression:
S(n) = a(1) ( 1 - r^n) / 1-r
S(9) = 4 (1 - 2^9) / 1-2
S(9) = 2044
Therefore, the correct answer from the choices listed above is option B.
