Pedigree Analysis Is a Basic Method in Human Genetics Using the pedigree provided, answer the following questions. a. Is the proband male or female? b. Is the grandfather of the proband affected? c. How many siblings does the proband have, and where is he or she in the birth order?
A woman who sought genetic counseling is found to be heterozygousfor a chromosomal rearrangement between the second andthird chromosomes. Her chromosomes, compared to those in anormal karyotype, are diagrammed on the next page:(a) This woman is phenotypically normal. Does thissurprise you? Why or why not? Under what circumstancesmight you expect a phenotypic effect of such arearrangement?
Galactosemia is a recessive human disease that istreatable by restricting lactose and glucose in the diet.Susan Smithers and her husband are both heterozygous for the galactosemia gene.a. Susan is pregnant with twins. If she hasfraternal (nonidentical) twins, what is theprobability both of the twins will be girls whohave galactosemia?b. If the twins are identical, what is the probabilitythat both will be girls and have galactosemia?For parts (c–g), assume that none of the children isa twin.c.

A woman who sought genetic counseling is found to be heterozygousfor a chromosomal rearrangement between the second andthird chromosomes. Her chromosomes, compared to those in anormal karyotype, are diagrammed on the next page:(a) What kind of chromosomal aberration is shown?
Identical twins are produced from the same sperm and egg (whichsplits after the first mitotic division), whereas fraternal twins areproduced from separate sperm and separate egg cells. If two parentswith brown eyes (a dominant trait) produce one twin boy with blueeyes, what are the following probabilities?A. If the other twin is identical, he will have blue eyes.B. If the other twin is fraternal, he or she will have blue eyes.C. If the other twin is fraternal, he or she will transmit the blueeye allele to his or her offspring.D. The parents are both heterozygotes.
The second pedigree involves albinism, an autosomal recessive trait. A couple has a son with normal pigmentation, a daughter with normal pigmentation, and an albino son. Another couple has three children, a son with normal pigmentation and two daughters with normal pigmentation. The daughter from the first couple marries the man from the second couple and they have three children together: an albino son, an albino daughter, and a daughter with normal pigmentation.Draw the pedigree on the next page
What are the genotypes of the mother and father in the pedigree below? The pedigree shows albinism (an autosomal recessive trait). The shaded shapes represent albino individuals. a. mother - homozygous dominant; father - homozygous dominant b. mother - heterozygous; father - homozygous recessive c. mother - homozygous recessive; father - heterozygous d. mother - heterozygous; father - heterozygous e. mother - homozygous dominant; father - homozygous recessive
What kind of polymorphism is most likely represented?
In human beings, the gene for red‑green colorblindness (r) is sex‑linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal‑visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. What is the genotype of the woman's father? What is the probability that the couple's first child will be a non-freckled, normal visioned girl? What is the probability that the first two children born to the couple will be freckled and colorblind girls?
Using the given pedigree chart, suppose individuals III-1 and III-2 are expecting their sixth child. What is the chance (percent) that the sixth child will have the sickle cell trait?
