Child 2 is polydactylous, otherwise normal; Child 4 has cystic fibrosis and is polydactylous. What is the genotype of the mother?What is the genotype of child 3?What is the genotype of child 4?What is the chance that child 1 is heterozygous for cystic fibrosis?

PpCc; ccpp; ccPp; 1/2

Explanation: The complete correct question is as follows

A polydactylous woman, otherwise normal, marries a healthy normal man. Their four children have the following phenotypes:

Child 1 is normal in all respects; Child 3 has cystic fibrosis, otherwise normal Child 2 is polydactylous, otherwise normal; Child 4 has cystic fibrosis and is polydactylous. A. What is the genotype of the mother? B. What is the genotype of child 3? C. What is the genotype of child 4? D. What is the chance that child 1 is heterozygous for cystic fibrosis?

We represent the traits of the parents with the following

P= Polydactyly

p=normal

C= normal

c= abnormal (cystic fibrosis

A. What is the genotype of the mother

Mother PpCc (polydactylous)

Father: ppCc (healthy normal)

B. What is the genotype of child 3?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child 3 will be ccpp (abnormal with cystic fibrosis)

C. What is the genotype of child 4?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child 4 will be ccPp

D. What is the chance that child 1 is heterozygous for cystic fibrosis?

Applying the mendel's cross link between the mother's genotype and father's genotype,

PpCc × ppCc

Child will be

The chance is 1/2

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.

the answer is c. resource depletion
