The young woman shown at right has albinismvery pale skin, white hair, and pale blue eyes. This phenotype is due to the absence of melanin, which imparts color to the skin, hair, and eyes. It typically is caused by a recessive allele. In the following situations, what are the probable genotypes of the father, the mother, and their children? a. Both parents have normal phenotypes; some of their children are albino and others are not. b. Both parents and all their children are albino. c. The mother is not albino, the father is albino, and one of their four children is albino.
Alleles for Tay-Sachs disease are inherited in an autosomal recessive pattern. Why would two parents with a normal phenotype have a child with Tay-Sachs? a. Both parents are homozygous for a Tay-Sachs allele. b. Both parents are heterozygous for a Tay-Sachs allele. c. New mutations gave rise to Tay-Sachs in the child. d. b or c
Red-green color blindness is inherited through an X-linked, recessive allele (b). Two parents, Fred and Ginger, have normal vision. They have two daughters, Takiyah and Kelly, who also have normal vision, and a color-blind son, David. 3. Daughter Kelly has a color-blind son, Kevin. Daughter Takiyah has five sons, all with normal vision. What are the genotypes of all the individuals? Show all your work! Fred Ginger David Takiyah Kelly Kevin Takiyah's five sons If Kelly marries a man with normal vision, what is the probability that she'll have a color-blind son? a color-blind daughter?
Cystic fibrosis (CF) is an autosomal recessive trait. A three-generation pedigree is shown below for a family that carries the mutant allele for cystic fibrosis. Note that carriers are not colored in to allow you to figure out their genotypes. Normal allele = F CF mutant allele = f What is the genotype of individual #8?
Hair texture is specified by wither curly or straight hair, both of which are dominant traits. A person heterozygote for hair texture has wavy hair. Hemophilia in humans if an X-linked recessive disorder. Harry's mother has curly hair and his father has straight hair. Harry also has hemophilia. Harry's wife is heterozygous for both traits a. show the genotypes of Harry and his wife b. show the punnett square c. what is the chance that the daughters of this couple are heterozygous for both traits d. what is the chance that any of their daughters will suffer from hemophilia e. what is the change that any of their sons will not have the disease hemophilia and will be heterozygous with respect for hair color f. what is the chance that any of their sons will suffer from hemophilia g. what percentage of their children will have curly hair, what percentage will have straight hair, and what percentage will have wavy hair
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.
A couple is going to have a baby. They are concerned about sickle cell anemia, which results from having the homozygous recessive combination of the sickle cell gene ("s"), which produces abnormal hemoglobin. Having at least one normal version of the gene ("S") results in normal hemoglobin. The woman is heterozygous, and so is the man. What alleles does mom have? What alleles does dad have?
A. Four babies are born in a hospital and are mixed up. Based on the blood type and hairline, match the baby to its parents. Type A blood and Type B blood are codominant and type O is recessive. Widow's peak is dominant to a straight hairline. Each baby has the following phenotypes: Baby A = B blood, widows peak Baby B = B blood, straight hairline Baby C=AB blood, straight hairline Baby D = O blood, straight hairline The phenotypes of the parents are as follows: Ms. Smith: A blood, widows peak Mr. Smith: B blood, straight hairline Ms. Jones: O blood, widows peak Mr. Jones: O blood, widows peak Ms. Black: AB blood, widows peak Mr. Black: O blood, straight hairline Ms. Green: B blood, straight hairline Mr. Green: B blood, straight hairline which the The parent cell b
In humans, the ability to roll your tongue is an autosomal dominant trait (T); the inability to rol your tongue is recessive (tt), having a cleft chin ai an autosomal dominant (N) and the lack of the cleft chinn is recessive (nn). A man can roll his tongue and has a clift chin; his father can not roll his tongue and didn't have a cleft chin. The man is married to a woman who can roll her tongue and who has a cleft chin; her mother coud not roll her tongue and didn't have a cleft chin. What are the possible genotuypes and phenotypes of the children? Woman's genotypes? Man's genotypes? Woman's gamete alleles? Man's gamete alleles?

Albinism is a recessive autosomal trait for skin pigmentation. Hemophilia is a sex-linked recessivedisorder of the blood. assign alleles to the traitsA – normal skin pigmentation X H – normal blooda – albino X h - hemophilia A double heterozygous woman marries a non-hemophilic man and heterozygous for skinpigmentation.  Double heterozygous means heterozygous for both traits. Aa for skin pigmentation andX H X h for blood trait. Therefore, the genotype of the woman is AaX H X h .  Non-hemophilic man is X H Y and heterozygous for skin pigmentation is Aa. The genotype,therefore, of the man is AaX H Y. What is the probability that they will have:a. a child with normal skin? _____________________b. a child with normal blood? _____________________c. an albino girl? _____________________d. A hemophilic boy? _____________________
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 If Andrea and Claude are carriers for the albino allele, what is the probability that they have an albino child? If Andrea and Claude have a second child, what is the probability this child be normal (non-albino)? NOTE: Draw a punnet square or show your work.
