Cystic fibrosis is an autosomal recessive disorder. In one population, the frequency of affected individuals (A 2 A 2) is 0.0004

Simora [160]

Hardy Weinberg Equilibrium

Explanation:

Hardy Weinberg Equilibrium formula for allelic frequency is: $p+q=1$

Hardy Weinberg Equilibrium formula for genotypic frequency is: $p^2+q^2+2pq=1$

Here, $p$ =frequency of dominant allele

$q$ =frequency of recessive allele

$p^2$ =frequency of dominant genotype

$q^2$ =frequency of recessive genotype

$2pq$ =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: $q^2$ =0.0004

If $q^2$ =0.0004 $q$ will be 0.02;frequency of recessive allele will be 0.02

Using the formula $p+q=1$

$p+0.02=1\\p=1-0.02=0.98$

hence,frequency of dominant allele will be 0.98

Frequency of dominant genotype will be $p^2=(0.98)^2=0.9604$
Frequency of heterozygous genotype will be $2pq=2*0.98*0.02=0.0392$

Step2247 [10]

Answer:

LLgg, Llgg , two out of 16

Explanation:

Given,

Dominant - Long wings and Gray color

Recessive - Short wings and Brown color

Let the allele for long wings be "L" and the allele for short wings be "l".

Let the allele for brown color be "g" and allele for gray color be "G"

Genotype of parents

LlGg

Gametes of the parent

LG, Lg, lG, lg

Dihybrid cross is between LlGg and LlGg

The offspring produces will be as follows -

LG Lg lG lg

LG LLGG LLGg LlGG LlGg

Lg LLGg LLgg LlGg Llgg

lG LlGG LlGg llGG llGg

lg LlGg Llgg llGg llgg

Offspring with long wings and brown color – LLgg, Llgg , two out of 16
