In purebred Labrador retrievers, the dominant fur-color allele, B, results in black fur, and therecessive allele, b, results in yellow fur. Suppose the Happy Labrador Ranch breeds yellowand black Labrador retrievers. The Ranch is expecting a new litter of four puppies, and theowners want to calculate the probability that the puppies will be either all black or two will be BB or Bbbbblack and two will be yellow. The parents of the new litter are both black and heterozygous,Bb, for coat color.Calculate the probability that the new puppies will be either all black or two will be black and two will be yellow. Enter theprobability as a decimal rounded to the nearest thousandth.probability:

Given : P(black puppy) = 24 P(yellow puppy) = 24

Answered: In purebred Labrador retrievers, the…

It is estimated that 1% of the population has a certain genetic defect. A medical test is used to determine if people have this defect and, if a person has this defect, the test will correctly indicate this with probability 90%. However, if a person does not have this defect, the test will still indicate that he or she has the defect with probability 9.6%. If a person tests positive for this defect, what is the probability that the person actually has the defect? Express your answer, rounded to three decimal places, if necessary.
The blood-typing system is based on the presence or absence of antigens. A person with antigen A has blood type A. A person with antigen B has blood type B, and a person with both antigens has the blood type AB. If there are no antigens, then the blood type is O. In addition, blood types are also identified as Rh-positive or Rh-negative based on a different antigen. What is the probability that a person has the A antigen or is Rh-positive?

On Mr. Casper's debate team at Thunderbird High School, 20% of the members are Sophomores, 35% are Juniors and 45% are Seniors. A team member is selected randomly to give the closing argument for the team. If a sophomore gives the closing argument, the team has a probability of 0.25 of winning the debate. If a junior gives the closing argument, the probability of winning is 0.6. If a senior closes, the probability of winning is 0.85. (a) Find the probability that the team wins the debate. b sketch a tree diagram to model this process
3. Draw a 4-color spinner (red, green, yellow, blue) such that landing on green is twice as likely as landing on red; landing on yellow is equally likely as landing on green; landing on blue is more likely than landing on yellow. Determine the probabilities of landing on each of the colors on your spinner and explain your reasoning Could someone else make a different spinner that has the same properties above but has different probabilities than yours?
According to the Center for Disease Control and Prevention (CDC), up to 20% of Americans contract the influenza virus each year, and approximately 3% of all births in the United States result in birth defects each year. Consider two randomly selected Americans and assume that these two randomly selected Americans are independent of each other. The probability that neither of these two randomly selected Americans will contract the influenza virus in a given year is
With regards to a particular gene, the percentage of genotypes AA, Aa, and aa in a particular population are respectively, 60%, 30%, and 10%. Furthermore, the percentages of these genotypes that contract a certain disease are respectively. 1%, 5% and 20%. If a person does contract the disease, what is the probability that the person is of genotype AA?
