5. Consider the following tetrahybrid
self-cross:
Aa Bb Cc Dd X Aa Bb Cc
Dd
Calculate the probability for each of the following offspring.
Show your work.
Genotype Aa BB CC Dd
Heterozygous for ALL FOUR genes
Heterozygous for ANY gene
Dominant phenotype for ALL FOUR traits
GIVEN that an individual offspring has the dominant phenotype
for all four traits, what is the probability that individual is
heterozygous for all four genes?
GIVEN that an individual offspring has the recessive...
An organism is heterozygous at three genetic loci (Aa, Bb and
Cc) located on different chromosomes. Explain how these alleles are
transmitted by the process of A) mitosis to daughter cells, and B)
meiosis to gametes Show the final genetic composition of the
daughter cells or gametes with respect to these loci? C. How many
different allelic combinations are possible with 8 heterozygous
loci on 8 different chromosomes?
Peas heterozygous for three independently assorting genes were
intercrossed.
(example cross: Aa Bb Cc x Aa Bb Cc )
What proportion of the offspring will be homozygous for one gene
and heterozygous for the other two?
(hint: apply binomial expansion equation)

A man (Bob) is heterozygous for Aa Bb Cc, where the genes show
independent assortment: He does not have a known phenotype, and
neither does their mother; but their father does. (A third eye). We
know it has to be associated with one of the three given loci. He
has 3 three children (1 boy and 2 girls) with a woman who is also
phenotypically normal, of which one girl has a third eye. Based on
this information, what type...
A fair coin is tossed three times and the
events AA, BB, and CC are defined as
follows:
A:{A:{ At least one head is
observed }}
B:{B:{ At least two heads are observed }}
C:{C:{ The number of heads observed is odd }}
Find the following probabilities by summing the
probabilities of the appropriate sample points (note that 0 is an
even number):
(a) P(not C)P(not C) ==
(b) P((not A) and B)P((not A) and B) ==
(c) P((not A) or B or C)P((not A) or B or C) ==
3.
Morris Industries manufactures and sells three products (AA, BB,
and CC). The sales price and unit variable cost for the three
products are as follows:
Product
Sales Price
per Unit
Variable Cost
per Unit
AA
$55
$25
BB

20
CC

Their sales mix is reflected as a ratio of 5:3:2. Annual fixed
costs shared by the three products are $275,000 per year.
A. What are total variable costs for Morris
with their current product mix?

1. Consider the regular grammar G given below:
S → aS|aA|bB|λ
A → aA|bS
B → bB|aS
(a) Give a derivation for the strings aabbba and baaba
(b) Give an infinite language L such that L is not a subset of
L(G)
(c) Give a regular expression that describes the language
L(G).
Assuming independent assortment of each gene, in the cross
female mouse: Aa Bb cc Dd ee FF x male mouse: Aa bb Cc Dd ee fY.
Assume all of these genes have simple dominance/recessive
relationships. The F/f genetic locus is on the X chromosome in
mice.
(a). What is the expected ratio of F1 progeny that will be
phenotypically identical to the female parent?
(b) What ratio of progeny will be genotypically identical to
the female?
(c) . What ratio...
If the a and b loci are 20 cM apart and an AA BB individual and
an aa bb individual mate: What gametes will the F1 individuals
produce, and in what proportions? What phenotypic classes in what
proportions are expected in the F2 generation (assuming complete
dominance for both genes) (show procedure, NO score for direct
result)?
