A couple, Jane and Biron, tell you that Jane's sister Maureen has Hurler syndrome, which is a monogenic disease caused by a recessive allele. Neither Jane or either of her parents are affected. They are concerned that they might have a child with the same disorder. Knowing that the frequency of affected individuals is 1 in 100,000, what is the probability that this couple's first child will have Hurler syndrome? Show work

Mr. and Mrs. Flynn are concerned because their new baby doesn't resemble either of them and has type O blood. Mr. Flynn is type A and Mrs. Flynn is type B. They're sure that it's impossible to have a baby with a different blood type than the parents, and so they conclude that a mistake has been made. Are they correct? Explain your answer. Be specific. Use the correct blood alleles (IA, IB, i) in your explanation.   genotypes:   Mr. Flynn _________         Mrs. Flynn __________           their baby ___________ Display keyboard shortcuts for Rich Content Editor

Farah breeds and sells true-breeding black salamanders.  At a salamander convention, she purchased a single red salamander from a breeder who told her the red color was an autosomal recessive trait. Describe a breeding program Farah could use to establish a strain of all red salamanders to sell. Include the phenotypic and genotypic ratios of offspring in each generation (F1, F2, etc.). You may assume that Farah can get hundreds of offspring from each mated pair, and that it's ethically okay for sibling salamanders to mate.

A horse breeder for the Kentucky Derby recently noticed that one of his  female horses gave birth to an offspring, a daughter horse, that had  several desirable traits to be a successful racing horse. The offspring had  a well-chiseled head on a long neck, high withers, a deep chest, a short  back, good depth of hindquarters, a lean body, and long legs. The farmer  would like to identify which male horse is the offspring’s father for  selective breeding purposes. He asks a local university to run a DNA  fingerprint with DNA samples from the mother, offspring, and the four  male horses on the farm.

In the USA the frequency of carriers for the devastating autosomal recessive trait of procrastination is 1/10 people. You do not procrastinate and want to have a child with another highly efficient non-procrastinator. You are worried that you both might be carriers and that your child would be a procrastinator. What is the probability that you are a carrier, AND your mate is a carrier, AND your child is procrastinator?

The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape  while the dominant phenotype is a round shape . Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. If their next child is a boy, there is a _____% chance it will be round.

The chart below is showing 4 generations of a family that is affected by a hereditary disease. a. Is the disorder being tracked dominant or recessive? How do you know? b. There is only one possible genotype for person C. True or False? c. What are the possible genotypes for person A? d. What are the possible genotypes for person B?, e. If two people with the same genotypes as person C's spouse and person A's spouse had a child, what is the probability that the child will be affected by this genetic disorder? (draw a Punnett square using the correct genotypes to help you). % chance offspring will be affected % chance offspring will not be affected

Color blindness is typically an inherited genetic condition in which individuals have a decreased ability to see color or differences in color. Color blindness only occurs in individuals who have two recessive alleles for the condition. Normal color vision is due to a dominant allele (C) Color blindness is due to the recessive allele (c) a) If Susan is homozygous for normal vision, and Matt is homozygous for color blindness, what is the likelihood (in percentage) that their son Alex will have color blindness? Perform a Punnett Square (either below or by hand on paper) to find the probability. Provide your answer in a full sentence. If you did the Punnett Square by hand, attach your photo to the next question.

Parents often want to know what is genetically possible for their children. If two parents are carriers for a recessive lethal trait, what are the odds that their child is also a carrier? Many times there is interest in tracking multiple traits at once (not just 1 or 2). The same probability rules apply here, you just multiple all the odds together at once. Imagine two parents. They are both carriers for red hair, one person is blood type AB, the other is type O. They want to know the odds of a daughter with red hair and type B blood. Please do no not do a giant Punnett square! Use probability or individual squares. a. What are the genotypes of the parents? b. What are the odds of each trait (daughter, red hair, type B)
