In a human family,the female has a form of deafness determined by an autosomal recessive allele.What's the probability that her phenotypically normal brother is heterzygous for the gene?
the probability is 1/2. The brother with the normal phenotype could have two alleles without a form of deafness or he could be a heterozygote. If he has a heterozygote...

If the homozygous dominant genotype makes up 36% of the population what is the frequency of the dominant allele in that population?
According to the Hardy-Weinberg Law (p^2+2*p*q+q^2=1) a frequency of the homozygous dominant genotype is p^2 = 36%/100= 0.36, therefore the frequency of the dominant allele in that population is the...

If eighteen of the panthers are heterozygous and if homozygous recessive individuals die before reproducing, what is the genotype for the remaining two panthers?
They are homozygous dominant, because it is the only remaining genotype among the three possible.

What are the phenotype and genotype ratios for a mix between homozygous dominant flower with red (R) pedals and a homozygous recessive flower with white (r) pedals?
RR x rrF1: 100% RrIf complete dominance than phenotype will be 100% red flowersIf incomplete dominance – 100% pink flowers

What are the phenotype and genotype ratios for a mix between a heterozygous dog with black (B) for and a homozygous recessive dog with brown (b) fur?
Phenotypic ratio; 1:1Genotype ratio; 1:1Explanation;Phenotype being the observable characteristic of an individual, the resulting offsprings will be 2 black and 2 brown dogs hence a ratio of 1:1Genotype being the genetic...

A disease causing allele is recessive. Assume that the male parent doesn’t have the disease and the female parent has the disease. What percentage of sons will have the disease?
Let assume that the disease-causing allele is a and healthy allele is A. As the female parent has the disease, it could be assumed that the genotype of the female...

If you cross a homozygous dominant almond shape eyes with homozygous recessive round shape eyes, what is the probability that the offspring will have phenotype of almond shape eyes?
Almond shape eyes - dominant trait, let it be Rround shape eyes - recessive trait, so it will be rThe cross : RR * rrOffspring: Rr (so the phenotype -...
