Imagine that a couple is planning to have children. The male is heterozygous for Huntington’s disease and homozygous dominant for Tay-Sachs. The female is homozygous recessive for Huntington’s disease and heterozygous for Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or Huntington’s. For humans, Huntington’s disease is dominant (H) over the “normal” condition (h), and the “normal” condition is dominant (T) over Tay-Sachs (t). Complete a Punnett square for this cross and record the probabilities for genotypes and phenotypes of the offspring as ratios.

In earlobes, free (F) earlobe is dominant while attached (f) earlobe is recessive. What proportion of the offspirng would we expect to have attached earlobes in the following crosses: 1.

Purple Hair is dominant. Blue hair is recessive. One parent is heterozygous; the other parent has blue hair. A.) What is the probability of them having a blue-haired child?
Both red/green color blindness (R=normal, r=colorblind) and Duchenne-type muscular dystrophy (D=normal, d=muscular dystrophy) are X-linked recessive traits that map close to each other. A woman has a father who is red/green color blind. Her mother's family has a history of Duchenne's muscular dystrophy. This woman is apparently healthy with neither color blindness nor muscular dystrophy. She marries a healthy man and they have four sons and two daughters. Half the sons are healthy but color blind, the other half have normal color vision, but have Duchenne's muscular dystrophy. The daughters are both normal. What is the genotype of the woman? ** The notation is written as X/X (so the / separates the two X chromosomes in a female) Group of answer choices RD/rd rd/rd Rd/rD RD/RD

For Dalmatian dogs, the spotted condition is dominant over non-spotted. (a) Using a Punnett square, show the results of a cross between two heterozygous parents. ( please draw the punnet square and write the parent and G and f1: thanks) (b) A spotted female Dalmatian dog mates with an unknown father. From the appearance of the pups, the owner concludes that the male was a Dalmatian. The owner notes that the female had six pups, three spotted and three non-spotted. What are the genotype and phenotype of the unknown male?

An allelic series determines coat color in rabbits: C (full color), c (chinchilla, gray color), c` (Himalayan, white with black extremities), and c (albino, all white). The C allele is dominant over all others, c is dominant over over c, and c is recessive to all other alleles. This dominance hierarchy can be summarized as C > c the table are crossed and produce the progeny shown. h Cc X c c Parents full color × albino Himalayan x albino full color x albino full color × Himalayan full color X full color Cross A B C D 50% full color, 25% Himalayan, 25% albino 75% full color, 25% albino E Match the parental genotypes to the letter corresponding to the appropriate cross listed in the table.

Colour-blindness is the result of an X-linked recessive allele, Xc. The allele for normal eyesight is XC. (a) A woman with normal colour vision whose father was colour-blind marries a colour-blind man. Give the genotypes and phenotypes of their children. What ratio of their children can be expected to be colour-blind? (b) A man with normal colour vision whose father was colour-blind marries a woman carrier of the colour-blind allele. What is the likelihood that their children will be colour-blind? Carriers of the trait?
