Answer #1

There are several ways to identify if the given gene is dominant or recessive.

1. Test Cross - However this is not a practical approch for human to identity the allele, but it is the best method in plants hybridisation.

2. Pedegree analysis - is the most suitable method to identify the allele. in the pegeree analysis character associated is observed in the familial history. if a allele is doiminent then its frequency of expression is higher then recessive. as recessive must have to be in homozygous to express its character.

Assuming a straightforward dominant/recessive relationship, what makes an allele “dominant” to the other one? If you were trying to determine which of two alleles for a particular gene was dominant, what kind of individual could you look at to answer this? (For example, if you had three individuals, one homozygous for Allele 1, one heterozygous, and one homozygous for Allele 2, which would be most helpful?)

3) In general, p = allele frequency of the dominant allele and q = allele frequency of the recessive allele. Using the product and/or sum rule(s), use these variables (p and q) to determine the probabilities of an individual in the next generation being: a) Homozygous dominant (A dominant allele (A) AND another dominant allele (A))? b) Homozygous recessive (A recessive allele (a) AND another recessive allele (a))? c) Heterozygote (Aa OR aA)? 4a) In a population in Hardy-Weinberg equilibrium,...

Suppose the human trait for dimplesis controlled by a simple dominant and recessive relationship at one locus. You wanted to determine the frequency of people with dimples in the city of Doral. Of the 1500 people you surveyedin downtown Doral, 1172 have dimples. Calculate the frequency of the having dimples –dominant allele,D–and the heterozygous genotype, Dd. Express the frequencies in decimal form rounded to the nearest thousandth. Assume the population in the city of Doralis in Hardy-Weinberg equilibrium for this...
