- Wooly, curly hair is due to a rare dominant allele (H) and its recessive allele (h) produces straight hair. Another gene has 2 alleles: (B) dark hair is dominant over (b) blonde. A woman with wooly, blonde hair marries a man with straight, dark hair. Their daughter has straight, blonde hair. What phenotypes and in what proportions can they expect among future children?Phenylketonuria (PKU) is a human hereditary disease resulting from the inability of the body to process the chemical phenylalanine, which is contained in the protein we eat. PKU is manifest in early infancy and, if it remains untreated, generally leads to cognitive impairment. PKU is caused by a recessive allele with simple Mendelian inheritance. A couple intends to have children but consults a genetic counselor because the man has a sister with PKU and the woman has a brother with PKU. There are no other known cases in their families. They ask the genetic counselor to determine the probability that their first child will have PKU. What is this probability?Create a hypothetical person and situation as a real life example to illustrate your position. Who is this person? How old is this person? What chromosomal abnormalities does this person have? How does genetic testing and counseling make this person’s life better or worse? Ultimately, should your hypothetical person seek genetic counseling?

The genotypes of Angela's parents are: O Mother: AA, Father: aa O Mother: aa, Father: AA O Mother: Aa, Father: aa O Mother: Aa , Father: AaAlbinism is inherited through a recessive allele (a). Juan has normal skin color. His Mom and Dad also have normal skin color. Juan marries Paige, who also has normal skin color. Surprisingly, their first child is an albino. What is everyone's genotype?YOUR SISTER DIED FROM TAY-SACHS DISEASE, INHERITED AS A RECESSIVE ALLELE (t). you're married and planning to start your family. you're worried about the disease and decide to have genetic testing to see if you or your spouse is a carrier of the tay-sachs allele. the test results show that you're a carrier of the allele, but your spouse isn't. what is the probability that you and your spouse will have a child with tay-sachs disease? show your work.
- Almond-shaped (E) eyes is dominant over round eyes. Presence of freckles (F) is also a dominant trait. Medium-sized nose, however, may be inherited if one parent has a large (L) nose and the other has a small (S) nose. Achondroplasia (A) is an autosomal dominant disorder that leads to dwarfism but not lethal.A woman homozygous for normal height, with freckles, almond-shaped eyes, small nose, and Type A blood, has a Type O mother with no freckles and a type AB father with round eyes. She is engaged to a man with achondroplasia, round eyes and medium sized nose. Unlike his father, hismother is of normal height. Both his parents have Type O blood but nobody from both sides of his family has or had freckles. 1.What is the complete genotypes of the man and the woman. Clearly indicate which genotype belongs to whom? 2.Based on their genotypes, what is the probability that they will have:- a child with Achondroplasia?- a child of normal height?- a child with type AB blood?Almond-shaped (E) eyes is dominant over round eyes. Presence of freckles (F) is also a dominant trait. Medium-sized nose, however, may be inherited if one parent has a large (L) nose and the other has a small (S) nose.

The oldest boy shows the symptoms of Duchenne Muscular Dystrophy (DMD). You are a geneticist and they come to you for advice. What would you tell them about the chances of their other children developing the disease?
- The allele for albinism ( c ) is recessive to the allele for normal pigmentation ( C ). A normally pigmented woman whose father is an albino marries an albino man whose parents are normal. They have three children, two normal and one albino. Give the genotypes for EACH person listed.Huntington's disease is an inherited autosomal dominant disorder that can affect both men and women. Imagine a couple has had seven children, and later in life, the husband develops Huntington's disease. He is tested and it is discovered he is heterozygous for the disease allele, Hh. The wife is also genetically tested for the Huntington's disease allele, and her test results show she is unaffected, hh. What is the percent probability that the first child of this couple will have Huntington's disease? probability: % What is the percent probability that two of the seven children will have Huntington's disease? probability: %Height is a polygenic trait. These students in a genetics class lined up, with shorter individuals on the left of the photo and taller individuals on the right, display a classic bell-shaped distribution. © McGraw-Hill Education/Photo by David Hyde and Wayne Falda
