Step 1
Squares represent males, circles represent females, filled shapes indicate individuals expressing the trait, and unfilled shapes indicate individuals not expressing the trait. The goal is to determine the genotypes (AA, Aa, or aa) of individuals and the Show more…

Problem 2 [17 points] Suppose the genotype of Betty is unknown, but the genotypes of her four grandparents are given by the chart below: Grandparents: BA AO AB AB Parents: Father ?? Mother ?? Child: Betty ?? (a) [2 points] What is the probability that genotype of both Father and Mother are AB? (b) [3 points] What is the probability that genotype of Betty is AB? The people with genotype AA, AO will have Phenotype A. (c) [3 points] What is the probability that Betty's Phenotype is A? (d) [3 points] What is the probability that both Betty's and Betty's brother's Phenotype are A? (e) [3 points] Given that Mother's phenotype is A, what's the conditional probability that Betty's Phenotype is also A? (f) [3 points] Given that Betty's phenotype is A, what's the conditional probability that Mother's Phenotype is also A?

What is the probability of getting an even number and a head? a. 1/4 b. 1/2 c. 1/12 d. 8/12 e. 7/12 3. You have a deck of cards. You choose one card. What is the probability of getting a jack or a club? a. 1/4 b. 13/52 c. 9/12 d. 16/52 e. 5/52 4. What is the probability of flipping 5 coins and getting a tail on the first flip and heads on the last 4 flips? a. 1/4 b. 1/2 c. 1/8 d. 1/16 e. 1/32 5. What is the probability of flipping 5 coins and getting 2 heads and 3 tails in any order? a. 10/32 b. 1/2 c. 1/8 d. 10/16 e. 1/32 6. Considering four gene loci, what is the probability that an individual with the genotype AaBbCcDd will produce a gamete that has the genotype A B C D ? a. 1/4 b. 1/2 c. 1/8 d. 1/16 e. 1/32 7. Consider a tetrahybrid cross (AaBbCcDd x AaBbCcDd), what is the probability that offspring will be homozygous dominant for all four traits (AABBCCDD)? a. 1/4 b. 1/16 c. 1/64 d. 1/128 e. 1/256 8. If a tetrahybrid is test crossed (i.e. crossed to a homozygous recessive individual, aabbccdd), what is the probability that a phenotypically recessive individual offspring will be produced? a. 1/4 b. 1/2 c. 1/8 d. 1/16 e. 1/32 9. In couch potato fleas, pink eyes are dominant to blue eyes and straight wings are dominant to curly. A cross between a homozygous pink eyed, straight wing female is mated with a blue eyed, curly winged male. The F1 progeny are then crossed to produce the F2 generation. What is the probability of producing a blue eyed, curly winged flea in the F2 generation? a. 1/4 b. 1/2 c. 1/8 d. 1/16 e. 1/32

Refer to the pedigree below for this question. Individuals who are shaded have the autosomal recessive disorder. Since it is a rare disorder, assume that anyone entering the pedigree (someone whose parents are not in the pedigree) is homozygous, unless there is evidence to the contrary. Those who are not shaded show the dominant phenotype. Let A and a represent the dominant and recessive alleles, respectively. Fill in the table below to indicate the genotype or probability function for the genotype of each individual. Give all probabilities as fractions that are simplified to the lowest value. Type your fractions in #/# format without spaces. For example, one-half should be entered as 1/2. Failure to correctly follow these directions will result in your answer being marked as incorrect. Fill in the table below to indicate the genotype or the genotype probability of the individual. Two are completed as examples. Individual Genotype Probability Formula I-2 0 AA + 1 Aa + 0 aa I-4 AA + Aa + aa II-2 AA + Aa + aa II-6 AA + Aa + aa II-7 1/3 AA + 2/3 Aa + 0 aa III-2 AA + Aa + aa III-3 AA + Aa + aa Give all probabilities as fractions that are simplified to the lowest value. Type your fractions in #/# format without spaces. Suppose that III-3 and III-8 have a child. What is the probability that their first child is genotype Aa?
