Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.

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?
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.
Albinism 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?
Albinism is an autosomal (not sex-linked) recessive trait. A man and woman are both of normal pigmentation and have one child out of three who is albino (without melanin pigmentation). What are the genotypes of the albino's parents? One parent must be homozygous for the recessive allele; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. Both parents must be homozygous dominant. 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. O000
Hemophilia is a sex-linked trait. A person with hemophilia is lacking certain proteins that are necessary for normal blood clotting. Hemophilia is caused by a recessive allele so use "N" for normal and "n" for hemophilia. Since hemophilia is sex-linked, remember a woman will have two alleles (NN or Nn or nn) but a man will have only one allele (N or n). A woman who is heterozygous (a carrier) for hemophilia marries a normal man: a.What are the genotypes of the parents? b.What is the probability that a male offspring will have hemophilia? c. What is the probability of having a hemophiliac female offspring?
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.

Two healthy parents have a child who is later diagnosed with cystic fibrosis. What is the genetic term for this kind of disease? Using Mendel’s pattern, pick a letter for this gene and give the genotypes of the parents and the child. What are the odds that their next child will also have cystic fibrosis?
The allele for albinism is recessive to the allele for normal skin pigmentation. All individuals who are homozygous for this recessive allele (m) are unable to produce the enzyme needed for melanin production and are referred to as albinos. In the following statements, determine the correct genotypes: An albino male (genotype A) whose parents both have normal skin pigmentation (genotype B) marries a woman who does not have albinism (genotype C). This woman’s father is an albino (genotype D). The married couple has three children, two with normal skin pigmentation (genotype E) and one exhibiting albinism (genotype F)
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.
Albinism causes the skin, hair, or eyes to have little or no color. It is also associated with vision problems. Albinism results from an allele a that is recessive to the allele for normal melanin production. Maya has normal skin color, but her sister has albinism. Maya’s mother has albinism, and her father has normal skin color. a)What are the genotypes of Maya, her sister, her mother, and her father. b)If Maya’s parents have another child, what is the probability that this child will have albinism? Show the Punnett square you use to help in solving. c)If Maya marries a man with albinism, what is the probability that their first child will have albinism?

A normal woman marries a man whose mother is colorblind. What is the probability of their children having color blindness? What percent is phenotypically normal
In humans, cystic fibrosis and albinism are both inherited as independently assorting autosomal recessive traits. Use f to represent the recessive allele for cystic fibrosis and F for the allele for the unaffected condition. Use A to represent the dominant allele for normal melanin and a for the recessive allele for albinism. A man is albino and heterozygous for cystic fibrosis. His wife has the unaffected phenotype for both traits, although her father had cystic fibrosis and her mother is albino. 4a. What is the genotype of the wife 4b.What is the probability that a child of this couple is albino and has cystic fibrosis? 4c.What is the probability that a child of this couple is a girl who is albino and has cystic fibrosis? 4d.What is the probability that a child of this couple is normal for both traits?
