Scientist Gregor Mendel (1822-1884) is often called the "father of modern genetics" and is famous for his work involving
the inheritance of certain traits in pea plants. Suppose that the genes controlling the color of peas are Y for yellow and y
for green. Each plant has two genes, one from the female (seed) and one from the male (pollen). The Y gene is dominant,
and therefore a plant with genes YY will have yellow peas, a plant with genes Yy or yY will have yellow peas, and a plant
with genes yy will have green peas.
If a plant with two yellow genes (YY) is crossed with a plant with two green genes (yy), the result is four hybrid offspring
with genotypes Yy. The offspring will be yellow, but will carry the recessive green gene.

Some traits of plants and animals depend on inheritance of a single gene. This is called Mendelian inheritance, after Gregor Mendel (1822-1884). Each of us has an ABO blood type, which describes whether two characteristics called A and B are present. Every human being has two blood type alleles (gene forms), one inherited from our mother and one from our father. Each of these alleles can be A, B, or O. Which two we inherit determines our blood type. Here is a table that shows what our blood type is for each combination of two alleles.

We inherit each of a parent's two alleles with probability 0.5. We inherit independently from our mother and father.
What is the probability that both children have different blood types?
Sickle cell anemia is an inherited disease in which red blood cells become distorted and
deprived of oxygen. A person with two sickle cell genes will have the disease, but a
person with only one sickle cell gene will have a mild, nonfatal anemia called sickle
cell trait. If we use s to represent
a sickle cell gene, and S a healthy gene, the
table shows the four possibilities for the
children of one healthy, SS parent, and one
parent with sicke cell trait, Ss. Find the
probability that these parents give birth to a
child who has sickle cell anemia.

Complete the table of expected counts under the null hypothesis: No Vitamin C 500mg Vitamin C 1000mg Vitamin C No Vitamin C 500mg Vitamin C 1000mg Vitamin C At least one cold 32.782 an association between the incidence of colds and the amount of an association between the incidence of colds and the amount of 18.529 10.69…arrow_forwardThere are X-Mart and Y-Mart convenience stores. It is assumed that each customer purchases once a week at one of the two supermarkets (but not both). In a study, a sample of 100 buyers was taken for 10 weeks. From this research it is known that if buyers go to X-mart store one week, 85 people will still buy at X-mart store the following week and if buyers go to Y-mart store one week, 70 people will still buy at Y-mart store. mart the following week. 1. Make a table and matrix of transition probabilities. 2. If John purchases at X-mart in the first week, what is the probability that Bob purchases at X-store in the third and fourth weeks?arrow_forward
- The National Electronic Injury Surveillance System tracks injuries reported from hospital admissions across the United States (Consumer Product Safety Commission 2018). For the data in 2017, we extracted all incidences of hand injuries that referenced punching a wall. There were 1843 such cases. The surveillance system also records some of the properties of the patients, including gender. Of all cases where a person was admitted to a hospital for injuries from punching a wall, 1352 were recorded as male and 491 were recorded as female. a. Do an appropriate hypothesis test to ask whether the proportion of males among wall-punchers is 50%.arrow_forwardIn a certain city, only 2 newspapers A and B are published. It is known that 25% of the city population read A and 20% read B while 8% reads both A and B. It is also known that 30% of those who read A but not B look into advertisement and 40% of those who read B but not A look into advertisements while 50% of those who read both A and B look into advertisements. What is the percentage of the population who read an advertisement?arrow_forwardMen have XY (or YX) chromosomes and women have XX chromosomes. X-linked recessive genetic di ievious question defective. Represent a defective X chromosome with lowercase x, so a child with the xY or Yx pair of chromosomes will have the disease and a child with XX or XY or YX or xX or Xx will not have the disease. Each parent contributes one of the retinoschisis) occur when there is a defective X chromosome that occurs without a paired X chromosome that is not chromosomes to the child. Complete parts a through d below. a. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a son will inherit the disease? (Type an integer or a decimal. Do not round.) b. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a daughter will inherit the disease? (Type an integer or a decimal. Do not round.) c. If a mother has one defective x chromosome and one good X chromosome and the…arrow_forward
