Chapter 14, Problem 13

The pedigree below traces the inheritance of alkaptonuria, a biochemical disorder. Affected individuals, indicated here by the colored circles and squares, are unable to metabolize a substance called alkapton, which colors the urine and stains body tissues. Does alkaptonuria appear to be caused by a dominant allele or by a recessive allele? Fill in the genotypes of the individuals whose genotypes can be deduced. What genotypes are possible for each of the other individuals?

Video transcript

Hello everyone here we have a question telling us all. Captain Urea is a biochemical disorder affected individuals cannot metabolize a substance called Al Qattan which occur which colors the urine and stains body tissues. Jack is married to Natasha. Jack is a normal person but Natasha is suffering from Al Qattan urea. Both have 50% of Children suffering from Al Captain Urea disease. Based upon these observations, we conclude that alcohol area appeared to be caused by a excellent dominant. A little bi zonal recessive, a little C. X linked recessive a little. The autism will dominant a little for Jack to be normal but still have Children. He at least needs to be hetero Ziegenfuss. So we're going to call him capital a lower case A. For Natasha to have it, she would have to lower case A's. And if we do our punnett square, we have capital A lowercase A. So a normal individual capital A lowercase A. Another normal individual to lower case A. And two lowercase A's. Which indeed gives us 50% of Children suffering from a Captain Urea. So this is this is in line with the conclusion that Alcatel Urea is an autism. A recessive trait. So our answer here is B Arizona recessive A little. Thank you for watching. Bye.

Textbook Question

In 1981, a stray black cat with unusual rounded, curled-back ears was adopted by a family in California. Hundreds of descendants of the cat have since been born, and cat fanciers hope to develop the curl cat into a show breed. Suppose you owned the first curl cat and wanted to develop a true-breeding variety. How would you determine whether the curl allele is dominant or recessive? How would you obtain true-breeding curl cats? How could you be sure they are true-breeding?

Textbook Question

In tigers, a recessive allele of a particular gene causes both an absence of fur pigmentation (a white tiger) and a cross-eyed condition. If two phenotypically normal tigers that are heterozygous at this locus are mated, what percentage of their offspring will be cross-eyed? What percentage of cross-eyed tigers will be white?

Textbook Question

In maize (corn) plants, a dominant allele I inhibits kernel color, while the recessive allele i permits color when homozygous. At a different locus, the dominant allele P causes purple kernel color, while the homozygous recessive genotype pp causes red kernels. If plants heterozygous at both loci are crossed, what will be the phenotypic ratio of the offspring?

Imagine that you are a genetic counselor, and a couple planning to start a family comes to you for information. Charles was married once before, and he and his first wife had a child with cystic fibrosis. The brother of his current wife, Elaine, died of cystic fibrosis. What is the probability that Charles and Elaine will have a baby with cystic fibrosis? (Neither Charles, Elaine, nor their parents have cystic fibrosis.)
