What is the probability that their next child will have the same phenotype as the first child? Assume that albinism is recessive to normal pigmentations and that this trait assorts independently from the blood group genotypes. Group of answer choices 3/16 9/16 1/8 1/4 1/16
- Albinism is a recessive disorder where there is a lack of melanin. Andrea and her husband Claude both have normal skin pigmentation. Andrea’s mother has the albino phenotype, but her father and her brother do not (normal pigmentation). Claude’s parents are both normal, but he has a sister who has the condition (is albino). Answer the following questions Determine the genotypes for Claude, Claude’s parents, and sister. NOTE: Draw a punnet square or show your work.Albinism is a recessive disorder where there is a lack of melanin. Andrea and her husband Claude both have normal skin pigmentation. Andrea’s mother has the albino phenotype, but her father and her brother do not (normal pigmentation). Claude’s parents are both normal, but he has a sister who has the condition (is albino). Answer the following questions Determine the possible genotypes for Andrea, Andrea’s parents, and brother (include all possible genotypes) NOTE: Draw a punnet square or show your work.An individual with a form of red-green color blindness processes a genetically inherited trait that makes it difficult to distinguish red and green color hues. Red-green color blindness tends to skin generations and it is found much more often in men than in women. If a man who was normal and a woman who is a carrier for this form of colorblindness have a child, when the probability that the child will be red-green colorbind is: -0% -25% -50% -75% -100%
- Cystic fibrosis is a genetic disease that causes an abnormal production of mucus which in turn can cause damage and infection to the lungs and other organs. In the following pedigree, black indicates all those persons afflicted with cystic fibrosis (square symbols are males, circles are females). There's a healthy couple and they have two children. One is a 23-year-old daughter with cystic fibrosis who is married to a 24-year-old male who is healthy. The other child is a 15-year-old son who is healthy After studying the pedigree, write a logical hypothesis suggesting the cause of cystic fibrosis in terms of dominant or recessive alleles. On the basis of your hypothesis, write an appropriate genotype for both of the parents. Using a Punnett square, what is the probability of the parents having a child with cystic fibrosis? If the daughter's husband is a carrier of cystic fibrosis, what is the probability that they have a child with cystic fibrosis? Show your Punnett square.A case of disputed paternity involves a woman, Miss X, two men, Smith and Jones, and five children.

The man denied it claiming that her current boyfriend was the father. The court ordered a blood test (cheaper than DNA testing) to see if he could be ruled out as the father. The mother was Type O and the baby was Type O. The man was Type AB. What is the possible genotype of the biological father? heterozygous Type A homozygous Type A heterozygous Type B
