Answer:
II and III
Explanation:
<em>I. All sons of these parents will be a hemophiliac. </em>
<em> II. A son who suffers from hemophilia received the hemophilia allele from his mother. </em>
<em> III. Half of the daughters of this cross are predicted to be hemophiliacs.</em>
Assuming the haemophilia allele is represented by h, the alternate form being H.
A woman that is a carrier will have the genotype .
A man who suffers from haemophilia will have the genotype
Crossing both of them:
x
=
From the result of the cross, the following can be deduced:
- Half or 50% of the sons from the couple will be haemophiliacs.
- Any son that suffers from haemophilia received the allele from the mother.
- Half or 50% of the daughters from this cross will be hemophiliacs.
Hence, statements II and III are true.
Hardy Weinberg Equilibrium
Explanation:
- Hardy Weinberg Equilibrium formula for allelic frequency is:
- Hardy Weinberg Equilibrium formula for genotypic frequency is:
- Here,
=frequency of dominant allele
=frequency of recessive allele
=frequency of dominant genotype
=frequency of recessive genotype
=frequency of heterozygous genotype
- frequency of affected individuals=0.0004(given)
here,affected individuals means the one's having Cystic Fibrosis and since it is recessive disease so we can write frequency of recessive genotype as: =0.0004
- If
=0.0004
will be 0.02;frequency of recessive allele will be 0.02
- Using the formula
- hence,frequency of dominant allele will be 0.98
- Frequency of dominant genotype will be
- Frequency of heterozygous genotype will be
