Question

Suppose two parents, a father with the genotype AaBbCcDdee and a mother with the genotype aaBbCCDdEe, want to have children. Assume each locus follows Mendelian inheritance patterns for dominance.

What proportion of the offspring will have each of the specified characteristics? Round your answers to two decimal places.
A. same genotype as the father
B. same genotype as the mother
C. phenotypically resemble the father
D. phenotypically resemble the mother
E. phenotypically resemble neither parent

Answer 1

To get the results, lets draw punnet square for each genotype.

a a

A Aa Aa

a aa aa

The results from this punnet square show that about 75% of the children will show the dominant phenotype as the father and 25% will show the phenotype of the mother. The genotype of 50% will be heterozygous dominant. The genotype of 25% will be homozygous dominant. The genotype of 25% will be recessive.

B b

B BB Bb

b Bb bb

The results from this punnet square show that about 75% of the children will show the dominant phenotype 25% will show the recessive phenotype. The genotype of 50% will be heterozygous dominant like the parents. The genotype of 25% will be homozygous dominant. The genotype of 25% will be recessive.

C C

C CC CC

c Cc Cc

The results from this punnet square show that all the offsprings will show the dominant phenotype. The genotype of 50% will be heterozygous dominant like the father. The genotype of 50% will be homozygous dominant like the mother.

D d

D DD Dd

d Dd dd

The results from this punnet square show that about 75% of the children will show the dominant phenotype 25% will show the recessive phenotype. The genotype of 50% will be heterozygous dominant like the parents. The genotype of 25% will be homozygous dominant. The genotype of 25% will be recessive.

E e

E EE Ee

e Ee ee

The results from this punnet square show that about 75% of the children will show the dominant phenotype 25% will show the recessive phenotype. The genotype of 50% will be heterozygous dominant like the mother. The genotype of 25% will be homozygous dominant. The genotype of 25% will be recessive like the father.
