Answer:

b yes-if the mother did not carry the trait (heterozygous) AND c yes-if the mother was not X b X b (homozygous)

Explanation:

Hemophilia is an X linked condition that causes abnormal bleeding due to a failure of the blood to clot. Because it is X linked, males only need to carry 1 allele to have the disease.

A father with hemophilia would have the genotype X b Y. However, since the son will also be XY, he must have passed on his Y chromosome, and the son must have got his X from this mother.

Therefore, there should not be any problems with abnormal bleeding following a circumcision.

However, this is only true if we assume the mother does not carry the trait. If one or two of her X chromosomes has the b allele (i.e. if she is a heterozygous carrier or homozygous for the trait), then the son could inherit the trait.

How to find the formula for the nth term​
snow_tiger [21]
“The nth term of the following types of sequences can be found out using the following Formulas:

1.Arithmetic Progression(AP) : here, the consecutive terms differ by a common difference (d).

tn= a+(n-1)d

Where,

a= is the first term of the sequence,

n= nth term

d= common difference

2. Geometric Progression(GP):

Here, the consequtive terms differ by a common ratio (r).

Tn= ar^(n-1)

where,

a = first term

r = common ratio

tn= nth term

3.Harmonic Progression (H.P):

It is the reciprocal of AP.

To find nth term of a HP, first convert it into AP and then apply the tn formula for the sequence and take the reciprocal of the obtained tn again.

Hope the answer helps you!!”
