In animals, the inability to produce pigmented melanin leads to albinism, a recessive disease. Two unaffected parents decided to have three children, and their first child had albinism (genotype aa). What is the probability that the second and third children will have albinism?
show me your work
Homework Answers
Answer = Since albinism is a autosomal recessive disease, affected individual have genotype aa.
PARENTS -: Aa ( Father ) × Aa ( Mother )
OFFSPRING -: AA Aa Aa aa ( Affected )
PROBABILIY For 2nd children = 1/4
Probability for 3rd children = 1/4
Together probability is = 1/4 × 1/4 = 1/16 that is 1/16 × 100 =
= 6.25 %

QUESTION 6 Albinism (lack of skin and hair pigmentation) is caused by a recessive autosomal allele. A woman and man both normally pigmented, have an albino child together. For this trait, what is the genotype of the albino child? O A. It is unknown, because not enough information is provided. O B. heterozygous O C. homozygous dominant OD.homozygous recessive O E. It depends on the environment that the child lives in. QUESTION 7 in...

B. Albinism Most humans (and vertebrates, in general) are genetically "programmed" to produce a brown skin pigment known as melanin. Albinism, the inability to produce melanin, is inherited in humans as an autosomal recessive trait. An individual with genotype AA or Aa will have normally pigmented skin, whereas an individual with genotype aa will produce no melanin. The albino's skin is very pale white. The white color occurs because one or more steps in the biosynthetic pathway for melanin do...

1. Tay-Sachs is an autosomal recessive disorder, which is the inability for infants to breakdown gangliosides in the CNS, which overtime build-up and destroy neurons. As the disease progresses, the child loses muscle control. Eventually, this leads to blindness, paralysis and death. If you have a family history of Tay-Sachs disease or if you're a member of a high-risk group and plan to have children, doctors strongly recommend genetic testing and genetic counseling. Scott and Tina are a young couple...

A human disease known as cystic fibrosis is inherited as a recessive trait. For example, the possible outcomes of a child inheriting cystic fibrosis genes are CC Cc cC cc if the child’s parents had one copy of each version of the gene so the probability of having a disease is ¼. Find the probability that 3 out of 6 children of these parents will have a cystic fibrosis.
