The MN blood group is a blood group controlled by a single gene with two loci. Individuals may be the type M (homozygous for the M allele), N (homozygous for the N allele), or MN (heterozygous). In a population 50 individuals have the blood antigen M, 15 individuals have the blood antigen MN and 35 individuals have the blood antigen N. Thus the frequency of the M allele in this population is ______ and that of the N alleles is ________.

Answer #1

The frequency of the M allele in this population is 0.575 and that of the N alleles is 0.425

As 50 individuals have the blood antigen M, 15 individuals have the blood antigen MN and 35 individuals have the blood antigen N

so total population is 100

MN is 15 so each M and N has 50% of it thatis 7.5

so individuals have the blood antigen M is 57.5 and hence allele frequency is 0.575 and individuals have the blood antigen N is 42.5 hence allele frequency is 0.425

The MN blood group is another blood group found on human red blood cells. There are only two alleles, M and N, which are codominant. In a population of humans there are 80 individuals that are MM, 150 MN, and 270 NN. Using the allele counting method, determine the allele frequencies for M and N.

In humans, the ABO blood type is controlled by a single gene with three possible alleles. Allele IA codes for blood type A and is co-dominant to allele IB which codes for blood type B. Allele i is recessive to the other two and codes for blood type O.

In a species of mouse, tail length is controlled by genes at a single locus, with the long tail allele dominant to the short tail allele. A population has 44 long tail and 36 short tail mice, with 27 of the long tail mice having a homozygous dominant genotype. Is this population in equilibrium?

This problem refers to the MN and ABO loci mentioned in class. It also refers to the Rh locus, which is responsible for the positive/negative part of the blood type. The Rh+ allele is dominant to the Rh- allele at this locus. Select all couples who could be the parents of a child with phenotype MN, A+ based on the phenotypes at these three loci. If none of these couples could be the parents of this child, select "None of...

The Kidd blood group in primates is inherited as a single gene with two codominant alleles (Jka and Jkb). We would like to verify that this locus actually follows simple Mendelian inheritance with codominant alleles in gibbons. We have a pure breeding population of Type Jka and a pure breeding population of Type Jkb. We create an F2 population and test for the antigens. Jka: 34 Jka Jkb: 81 Jkb: 34 Perform a chi square analysis on this data using...

There are three different alleles at the same locus that contribute to blood type. A homozygote for AA will be type A, a homozygote for BB will be type B, and a homozygote for ii will be type O. Heterozygotes exist as well, where A is codominant with B (producing type AB), and both A and B are dominant to i. In a population, 4% are type O, and 1% of the individuals are homozygous for type A. Fill in...

1. The MN blood group system is under the control of an autosomal locus found on chromosome 4, with two alleles designated LM and LN. The blood type is due to a glycoprotein present on the surface of red blood cells, which behaves as a native antigen. LM and LN are codominant and heterozygotes express both antigens and have blood type MN. In the following crosses, what will be the genotypes and phenotypes, and their ratios, in the offspring? a....
