Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman who both produce melanin have one child out of three who has albinism. What are the genotypes of the man and woman? O One parent must be homozygous for the recessive allele; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. One parent must be heterozygous; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. Both parents must be heterozygous. One parent must be homozygous dominant; the other parent must be heterozygous.

Redgreen color blindness is an X-linked recessive disorder in humans. Your friend is the daughter of a color-blind father. Her mother had normal color vision, but her maternal grandfather was color-blind. What is the probability that your friend is color-blind? (a) 1 (b) (c) (d) (e) 0
You decide to breed a pair of guinea pigs, one black and one white. In guinea pigs, black fur is caused by a dominant allele (B) and white is due to homozygosity for a recessive allele (b) at the same locus. Your guinea pigs have seven offspring, four black and three white. What are the genotypes of the parents? Why is there a 1:1 ratio in this cross?
Color blindness is a recessive X-linked trait. A normal couple has a color-blind child. At least one member of the couple's families is colorblind, who is this most likely to be?
f you have a recessive phenotype for a given trait, but neither of your parents has that phenotype, what can you say about the genotype of your parents for that trait? Both of your parents have to be hetorozygous One of your parents might be homozygous dominant but the other has to be hetorozygous Both of your parents must be homozygous dominant Both of your parents have to be homozygous recessive
Since each child of two heterozygous parents has a 1/4 chance of receiving a recessive trait from each parent. A)If the first child is phenotypically recessive, then the next child has 3/4 chance of being phenotypically recessive B)no matter what the first child's phenotype, the next child will have a 1/4 chance of being phenotypically recessiveC)if the first child is phenotypically recessive, then the next child has a 1/2 chance of being phenotypically recessive D)if the first child is phenotypically recessive, then the next child must be phenotypically dominant.
Since the Titanic sank Jack and Rose never got the chance to have children together. Rose spent the rest of her life wondering what their children would have looked like. Jack had golden-brown hair and Rose has red hair. Would their children have hair like the mother or father? Jack is heterozygous dominant for brown hair and Rose is homozygous recessive for red hair. Use your own letters for the alleles.
Albinism is a recessive trait. Two individuals who both have normal pigmentation have one child out of three who has albinism (without melanin pigmentation). What are the genotypes of this child's parents?
In humans, color blindness is a sex-linked recessive trait. A female who is a carrier (XBXb) for color blindness has children with a male with normal vision (XBY). Make a Punnett Square to help you answer the questions. What are the chances of their children being color blind? What are the chances of their children being ‘carriers’ for color blindness?

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? _____________________
