What is the probability that a lady has a red-haired gene? The probability of her mother having the gene is 2/3 and the probability of her father having the gene is 1/4.
Homework Answers
The lady can have red haired gene if she gets the gene from either her mother of her father
She won't have the red haired gene if both her parents does not have the gene
P(mother having the gene) = 2/3
P(mother not having the gene) = 1 - 2/3 = 1/3
P(father having the gene) = 174
P(father not having the gene) = 1 - 1/4 = 3/4
P(a lady has a red-haired gene) = 1 - P(she does not have a red haired gene)
= 1 - 1/3 x 3/4
= 3/4

A human gene carries a certain disease from a mother to her child with a probability rate of 0.54. That is, there is a 54% chance that the child becomes infected with the disease. Suppose a female carrier of the gene has five children. Assume that the infections, or lack thereof, are independent of one another. Find the probability that all five of the children get the disease from their mother. Question 16 options: 0.024 0.954 0.046 0.021
A woman with red-green color-blindness has a mother with normal vision.
A woman with red-green color-blindness has a mother with normal vision. Knowing that color-blindness is a sex-linked recessive gene, can you determine what her father's phenotype is? (yes or no) If so, what is it?The woman marries a man with normal vision. What is the probability they will have sons who are red-green color-blind? What is the probability they will have daughters who are red-green color-blind?

A mother is heterozygous for an over-expressed plastin allele on her X chromosome, thus has longer than normal axons. She is also heterozygous for the SMN1 gene on chromosome 5. Her children’s father is normal for plastin and has normal length axons. He too is heterozygous for the SMN1 gene. Both genes influence spinal muscular atrophy type 1 (SMA1); two abnormal copies of the SMN1 gene are required to cause spinal muscular atrophy, but their effect is prevented by high...

A certain disease can be passed from a mother to her children. Given that the mother has the disease her children independently will have it with probability 1/2. Given that she doesn't have the disease, her children won't have it either. A certain mother, who has probability 1/3 of having the disease, has two children. (1) Find the probability that neither child has the disease. (2) Is whether the older child has the disease independent of whether the younger child...

A quarter horse breeder wishes to test her award winning black, smooth-haired stallion to determine if he carries the recessive gene for curly hair. Assume she has access to: - 4 recessive homozygous curly haired mares -14 known carrier mates -15 daughters of the stallion -A population of 35 mares with the frequency of curly hair of 0.1 a).

A human gene carries a certain disease from the mother to the child with a probability rate of 47%. That is, there is a 47% chance that the child becomes infected with the disease. Suppose a female carrier of the gene has three children. Assume that the infections of the three children are independent of one another. Find the probability that all three of the children get the disease from their mother. 0.132 0.896 0.104 0.149
