- Codominance in blood types. If a male with type A blood (with genotype IAi) mates with a female having type B blood (with genotype IBi), what are the phenotypic ratios for the blood types of the offspring? ___ A : ___ B : ___ AB : ____ O Suppose that one parent has type AB blood, and the blood type of the other parent is not known. Describe how a child can (or cannot) have the following blood types: Type A Type B Type AB Type OMeasuring Genetic Diversity in Human Populations Why is it that mutation, acting alone, has little effect on gene frequency?mating population of chickens, 16 percent of the herd have green wattles (those neck flaps). Green is the autosomalrecessive (r) and 84 percent have Yellow wattles (R, the wildtype) If this population is assumed to be in Hardy-Weinberg equilibrium, what is the genotypic frequencies of RR and Rr?What is the genotypic frequency of RR?

The Mendelian pattern of inheritance is a general term that refers to any pattern of inheritance in which traits do not segregate in accordance with Mendel’s lawsII. As an example, a characteristic may be controlled by one gene with two alleles, but the two alleles have a same relationship like the simple dominant-recessive relationship a. The first statement (I) is correct and the second statement (II) is wrong b. The first statement (I) is wrong and the second statement (II) is correct c. Both statements are correct d. Both statements are wrong MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle.II.

AaBb AaBbD) Genetics Problem show the table and word In certain breeds of chickens, the allele "B" is responsible for black feathers whereas the contrasting allele "b" produces feathers that are white. Another r pair of alleles influences the shape of the feathers. "F" produces straight feathers whereas the contrasting gene for "f results in the frizzled condition. Give the genotypic and phenotypic ratios to be expected from the following cross: white, frizzled hen with a heterozygous black, homozygous straight rooster. Genotypic Ratio: Phenotypic Ratio:Hardy-Weinberg Problems Please be sure to SHOW ALL WORK in order to get credit. This assignment will be graded for accuracy. *Hint: Remember what p and q represent. Determine first if I am asking for allele frequency or genotype/phenotype frequency. Then determine which equation is appropriate. What does p and q represent in the equations? Which equation do you use if I am asking for allele frequency? If the frequency of the recessive allele is 0.1, what is the frequency of the dominant allele? If the frequency of the dominant allele is 0.4, what is the frequency of the recessive allele? If the frequency of the dominant allele is 0.6, what is the frequency of the homozygous dominant genotype? If the frequency of the homozygous recessive genotype is 0.81, what is the frequency of the recessive allele? If the frequency of the homozygous dominant genotype is 0.25, what is the frequency of the dominant allele? If the frequency of the…
