Suppose that you are studying is a rare recessive condition in humans whereby affected individuals are unable to metabolize a sugar found in certain foods. A woman and her husband are both heterozygous for the allele causing the condition.
A) If the woman is pregnant with twins and the twins are dizygotic (non-identical), what is the probability that both twins will be girls and be affected?
B) What is the probability if the girl twins are identical (monozygotic) and both are affected?
C) If the woman gives birth to four children, what is the probability that none of them will be affected?
D) If the couple has four children, what is the probability that one of will be affected?
E) If the couple has four children, what is the probability that the first two will be affected while the second two will be unaffected?
F) If the couple has three children, what is the probability that two will be affected while one will be unaffected, regardless of birth order?
G) If the couple has four affected children, what is the probability that a fifth child will also be affected?

Alpha thalassemia is a recessive trait in humans. Affected individuals suffer from anemia, weakness, and fatigue. A man and a woman are unaffected but are heterozygous for the normal and mutant alleles i.e they are carries. Based on mendel's law 1/4 of the children are unaffected. If they have five children, what is the probability of them having one affected and four unaffected children, in any order?

In humans, albinism is caused by a recessive allele (a) while normal pigmentation is caused by the dominant allele (A). a) If two pigmented parents have an albino child, what must the genotypes of the parents be? b) What is the probability that if they have another child, that child will be albino? c) What is the probability that the next two children are albinos? d) What is the probability that they have one albino and one pigmented child? Be...

A young couple falls in love and decides to marry and start a family. Assume that with each birth, they are equally like to have a boy or girl child - and only one at a time (no twins or other multiple births). They decide to keep having children until they have one girl. 5. a. On average, how many children will be born to this family? b. If there are no girls in the first two births, what is...
If both husband and wife are known to be heterozygous for the autosomal recessive condition of...
If both husband and wife are known to be heterozygous for the autosomal recessive condition of albinism, what is the probability that among their four children, three will be normal and one will have albinism? I know that each child has a 3/4 probability of being normal and 1/4 probability of having albinism. So is the answer 3/4 * 3/4 * 3/4 * 1/4? Or do you just do 3/4 * 3/4 * 3/4?

10. A rare condition known as adermatoglyphia leads to such smooth fingertips that the individual has no fingerprints. It has been dubbed the "immigration delay disease" because sufferers have such a hard time entering foreign countries Recently the cause has been traced to a point mutation in the very first nucleotide of an intron The allele with this mutation (F) is dominant to the wild type allele (f). The condition also leads to less hand sweat than the...

8. [12 pts total] Huntington disease is a rare degenerative autosomal disorder that determined by a dominant allele. The disorder is typically manifested after the age of 45. A young man has learned that his father has developed the disease; his mother does not carry the dominant allele for the condition [4 pts] A. What is the probability that the young man will later develop the disease? (4 pts] B. If the young man has a child with a woman...

Jack and his wife, Angela (27), have been referred to you by Angela’s gynecologist. Jack, a healthy male, has a family history of anhidrotic ectodermal dysplasia (ED). The couple has one unaffected son, aged 2 years, and are contemplating having a second child. Ectodermal dysplasia is a disorder characterized by absence of sweat glands and malformed or missing teeth. Some persons having ED also have unusual hair growth patterns and mental retardation. Persons having the disease are at risk of...

Hemophilia is an X linked recessive condition in humans (Xh). Blood type (AB) is determined utilizing multiple alleles of I, two of which are codominant. A widow's peak is determined by a single dominant allele (W), while the recessive phenotype is a straight hairline. The ability to taste PTC is determined by a single dominant allele (T). while the recessive phenotype is a non-taster. Eugene is a non-taster male who does not have hemophilia. He has AB blood and a...
