Q17. In a dog breed, a gene B coding for fur color has a dominant allele B for black fur. Gene B has a recessive
allele b that produces brown fur. A second gene I, has a dominant allele I that is epistatic to the color locus and
can inhibit pigment formation. Gene I has a recessive allele, i, on that permits pigment deposition in the fur.
Note: the inhibition of pigment formation by the epistatic allele I causes the fur to be white.

Think Critically. Provide a concise explanation of your answer.
A mutation on an autosome causes a particular protein to be overproduced, and the excess protein accumulates in the liver and damages it. Would the resulting disorder most likely be inherited in an autosomal dominant or recessive pattern?
Expression of the SYR gene on the Y chromosome gives rise to the male phenotype in humans. What do you think the inheritance pattern of SYR alleles is called?
22q11.2 deletion syndrome, also called DiGeorge syndrome, causes atypical parathyroid glands, a heart defect, and an underdeveloped thymus gland. About 85% of patients have a microdeletion of part of chromosome 22. A girl, her mother, and a maternal aunt have very mild DiGeorge syndrome. They all have a reciprocal translocation of chromosomes 22 and 2.
How can a microdeletion and a translocation cause the same symptoms?
Why were the people with the translocation less severely affected than the people with microdeletion?
What other…

In flies, long wings are a dominant trait, and short wings are a recessive trait. Medium wings are the heterozygous
trait. Based on this information, if a homozygous long-winged fly is crossed with another a heterozygous'fly, their
offspring will have which percentages for long, medium, and short wings? Assume random chromosome segregation.

Wild type mice have agouti fur where the individual hairs are black with a yellow band producing the typical grey-like colour of agouti fur. Two different independently segregating genes are involved in the expression of coat colour: • A single gene with two alleles, A and a, determines the colour of the coat; Agouti (AA or Aa) is dominant over black (aa). • A different gene is required for the hair pigment to be synthesised and therefore expressed. When the dominant allele of this gene is present (C), pigment is produced and the agouti and black phenotypes can be expressed. A null allele (c, which produces an inactive form of the enzyme for pigment production) is recessive; when in the homozygous form (cc), no pigment is produced and the mice are albino. a) Write down the colour of the coat of mice with the following genotypes: Genotype Phenotype aaCc b) Consider the following cross: Parents…arrow_forward10.
