In alley cats, the coat color is determined by a gene carried on the X chromosome. At the same time, the alleles are expressed as intermediate (nondominance) inheritance. Genotypes and colors are as follows: Females: XXb = yellow Males: XbY = yellow %3D XBXB calico XBY = black XBXB black 17. A calico cat has a litter of eight kittens: one yellow male, two black males, two yellow females, and three calico females. What is the color of the father of the litter? 18. A black cat has a litter of seven kittens: three black males, one black female, and three calico females. Comment on the probable paternity of this litter and explain. A yellow cat has a litter of four kittens: one yellow, and three calicos. Assuming a single father for the litter, what is the sex of the yellow kitten? 19.

The shape of a heliodor is an X-linked trait. Male heliodors inherit two X chromosomes, while the females inherit an X and a Y chromosome. The recessive allele codes for the common bell-shape  while the dominant phenotype is a round shape . Hudson is a round male and has offspring with Heidi, a bell-shaped female. They already have one daughter, Hannah, who is shaped like her mother. There is [blank] % that their next child will also be bell-shaped female like Hannah.

6) Duchenne muscular dystrophy (DMD) is a muscle wasting disease and is an X-linked recessive disorder. A man with this disease has children with a woman who does not have the disease, but her father did. If they had a ason, what would be the chance that he would have DMD? If they had a daughter? Any child? Construct a Punnett square to determine the answers. 10) In cats, coat color is completely dominant to albino (Mendelian genetics) and is an autosomal trait. Playa is a female albino cat and is crossed with Azul, a black-coated male. In their first litter, they have 4 black kittens and 2 albino kittens. If in the second litter, they have 8 kittens, how many of the kittens are expected to be albino? Construct a Punnett Square to determine the answer.

Ocular albinism is a sex-linked recessive disease carried on the X chromosome. A female carrier mates with a male with this disorder. What percentage of all of their children is predicted to be an albino female? 1) 0% 2) 25% 3) 50% 4) 75% 5) 100%

Red-green colorblindness is inherited in an X-linked recessive pattern in humans.  A colorblind man and a woman with normal vision have four children, and one of them is a colorblind male.   Does the mother have to be a carrier in this case?  (Yes or No) What is the probability of the next child in this family being both colorblind and male?   No, 25% Yes, 25% No, 50% Yes, 50%

What is the approximate percentage chance that individual V.2, shown in the pedigree diagram below will have inherited the X- linked recessive allele shown to be carried by his great-great-grandmother? Note: only type the number, not the percentage symbol. Answer: The chance that individual V.2 shown in the pedigree below has inherited the X-linked recessive allele shown to be carried by his great-great grandmother is approximately Blank 1 percent. 노 ㅍ먹이 12 I 마일 메인 de 먹어 요 58 ㅁ + ܡܐ

One type of colorblindness is an X-linked recessive trait. If a colorblind man and a woman with normal vision but whose father was colorblind have a girl, what is the probability she will be colorblind? If they have a boy what is the probability he will be colorblind? 1/2 for the girl; 1/4 for the boy O 1/2 for the girl; 100% for the boy O 1/2 for the girl; 1/2 for the boy 1/4 for the girl; 1/2 for the boy O for the girl; 1/2 for the boy
