In certain parts of Africa where malaria is prevalent there is an apparent advantage to being heterozygous for the recessive allele that causes sickle-cell anemia. Suppose a couple, both heterozygous for this allele, plans to have four children. What is the probability that all four will be heterozygous for the sickle-cell allele (assuming that none are from multiple births)? Explain how they can determine this using a Mendelian cross.

Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.

Marfan’s syndrome is an example of pleiotrophy where individuals with a copy of the dominant allele have skeletal disorders, mitral valve prolapse and characteristic slender, loose joints. If Abraham Lincoln had a marfanoid disorder which he inherited from his mother, what are the chances he passed this trait on to his offspring? Consider that Mary Todd Lincoln, his wife, was 5’2”. please include a punnett square
Imagine a cross between a man and a woman having the following genotypes: Genotype of the Husband Genotype of the Wife Aa bb Dd Gg Hh RR Tt X Aa Bb Dd gg Hh Rr Tt Assuming that the dominant allele in each gene pair exhibits complete dominance over the recessive allele, what is the probability that this couple would have a daughter who exhibits the recessive phenotype with respect to all seven of the gene pairs?
Assume that one of Merida's sons, who is heterozygous for orange hair color, married a girl that was also heterozygous. Create a Punnett square to show the possibilities that would result if they had children. a. List the possible genotypes and phenotypes for their children. b. What are the chances of a child with orange hair? c. What are the chantes of a child with yellow?
Hemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia. They would like to have one more child. What is the probability of having a child without hemophilia? Explain using a Punnett square. Is it possible for a girl to be born with hemophilia? Explain.
Doing genetic analysis it is determined that two parents are heterozygous for two separate unlinked recessive traits (i.e., both parents are heterozygous for both loci). Given this genetic information, what is the probability of their having a child which is homozygous recessive for both traits?
The blood serum from one individual (let’s call this person individual 1) is known to agglutinate the red blood cells from a secondindividual (individual 2). List the pairwise combinations of possible genotypes that individuals 1 and 2 could have. If individual 1is the parent of individual 2, what are his or her possiblegenotypes?
Cystic fibrosis in humans is caused by a recessive allele. A man is known to be a carrier of the cystic fibrosis allele. He marries a phenotypically normal woman. In the general population, the incidence of cystic fibrosis at birth is approximately 1 in 1,700. Assume Hardy-Weinberg proportions. What is the probability that the wife is also a carrier? Answer in decimal number only (three decimal places; example: 0.123). What is the probability that their first child will be affected? Answer in decimal number only (three decimal places; example: 0.123).
Achondroplasia is a hereditary disease with a very characteristic phenotypic manifestation. The disease is caused by a dominant allele. According to a 1986 study, the incidence of this disorder is as high as 1.5 affected per 10,000 newborns. Calculate the frequency of heterozygotes for this gene in a given population.
