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, O+ based on the phenotypes at these three loci. If none of these couples could be the parents of this child, select "None of...

Question 4 (1 point) Two loci are linked to each other. The Red hair locus is complete dominant in that the dominant allele (R) provides an individual with non-red hair and the recessive allele (r) provides an individual with red hair. The Freckles locus is completely dominant in that the dominant allele (F) codes for freckles and the recessive allele (f) doesn't cause freckles. You often see red hair and freckles occurring together, suggesting the two loci are linked. Provided...

Question 1 (10 pts). Ilne genetic linkage among 3 gene loci in norses is being stuaiea. ine loci are part of autosomal chromosomes and they MIGHT be on the same pair of homologous chromosomes. There are two alleles at each locus. At the coat color locus, allele B is for black, and b is for white. At the height locus, allele H is for tall, and h is for short. At the tail locus, allele T is for long, and...

2. In Labrador dogs, there are 2 loci that determine coat color. The first locus, B is dominant to b. At least one B allele will produce black coat color, while the bb genotype produces a chocolate coat color. This first locus also determines nose color in Labradors: B_ black noses, and bb brown noses. The second locus has a genotype, ee, that is epistatic in nature. Any Labrador with an ee genotype will be yellow. A genotype containing at...

A suspect in a rape case has been typed for three STR loci. His alleles match those of the evidentiary sample (semen taken from the rape victim) for each locus. He is a heterozygote for the first two loci and a homozygote for the third. The allele frequencies for locus 1 in the general population are .05 and .10. For locus 2 they are .07 and .02. for locus 3, the allele frequency in the general population is .08. what...

Genetics 1. A man with blood type B is the father of a child with blood type A, and the mom is blood type AB. What is the father's genotype? a. not enough information to determine the father's genotype b. AB c. Bo 2. What are the chances that a couple will have a boy with colorblindness, sex-linked recessive if the father is colorblind and the mother is homozygous dominant for normal color vision? a. 0% b. 100% c. 75%...
