This question is a better fit for Molecular genetics = Molecular biology + Genetics
Why are mutant tumour-suppressoor genes and oncogenes generally recessive and dominant respectively?
This fact can be easily explained from the functions of these genes. Tumour-suppressing genes “watch” cellular proliferation, differentiation, genome integrity etc. So, they have to be active constantly. Every cell...

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...

Parent 1 is red (Cc) and parent 2 is blue (cc). The offspring in the F1 generation are 50% red and 50% blue. Which allele is dominant? Which allele is recessive?
Parents produce the following gametes:Parent 1: C, cParent 2: c, cThe offspring genotypes are:50% Cc, 50% cc.If the blue allele was dominant, all the offspring would be blue. However, since...

If the relative frequency of the B allele decreased in the gene pool what would happen to the relative frequency of the other allele? Explain.
According to Hardy-Weinberg equation, p2 + 2pq + q2 = 1, where p is a frequency of the B allele, and q is a frequency of b allele. As the...

In a random mating population oo 28,800 individuals percentyage of dominant homozygous individuals is 49.find out the percentage of heterozygous individual
Solution: The frequencies of different types of genotypes in ideal population are described by the Hardy–Weinberg law: p^2 +2pq+q^2 =1 where p 2 is a frequency of dominant homozygotes, q^2...

A population of squirrels have 250 red-sided individuals and 750 tan-sided individuals. Assume that red is totally recessive. Calculate the allele frequencies of each allele.
Red-sides animals result from occasional combination between two recessive alleles. This even happens with the probability, which is equal to squared frequency of the recessive allele in population. The frequency...

In a random mating population of 20000, 16800 individuals are the dominant then how many individuals will be homozygous?
The number of individuals with recessive phenotype is 20000 - 16800 = 3200. Their proportion in the population is 3200 / 20000 = 0.16 As individuals with recessive phenotype can...

In humans, if P represents the dominant allele for extra fingers and toes (polydactyly) and p is the recessive 5-fingered allele, which of these genotypes would indicate a person with five fingers?
A person with five fingers will be homozygous recessive and he can have only one genotype possible- pp.PP and Pp genotype would indicate polydactyly.

In dragons, black body color is dominant to green body color. Cross one homozygous dominant dragon with one homozygous recessive dragon. What are the genotypes of the parents
Parents Genotypes ;The mother dragon is heterozygous for the wing gene (Ww) and the horn gene (Hh). The father is homozygous recessive for the wing gene (ww) and the horn...
