Title: An organism having the genotype AaBbCcDdEe is self-fertilized. Assuming the loci
Post by: sjohn092 on Jan 9, 2014
An organism having the genotype AaBbCcDdEe is self-fertilized. Assuming the loci assort independently, determine the following proportions:


gametes that are expected to carry only dominant alleles.
Express your answer using three decimal places.

progeny that are expected to have a genotype identical to that of the parent.
Express your answer using three decimal places.

 progeny that are expected to have a phenotype identical to that of the parent.
Express your answer using three decimal places.

gametes that are expected to be abcde .

progeny that are expected to have the genotype A_B_C_DdEE.
Express your answer using three decimal places.

AaBbCcDdEe x AaBbCcDdEe

Aa X Aa = 1/4 AA
Bb X Bb = 1/4 BB
Cc X Cc = 1/2 Cc
Dd X Dd = 1/4 dd
Ee X Ee = 3/4 E_

1/4 X 1/4 X 1/2 X 1/4 X 3/4 = 3/512 = 0.00585= 0.585 %

according to the 2n formula, the different types of gametes produced will be, 25= 32.

among all these 32 gametes, only 1 will carry out all the dominant alleles.

An organism having the genotype AaBbCcDdEe is self-fertilized. What are the proportion of gametes that are expected to carry only dominant alleles.

Aa

1/2

Bb

1/2

Cc

Dd
1/2

Ee
1/2


ABCBE----1/2 X 1/2 X 1/2 X 1/2X 1/2 =1/32 ANSWER
