A single gene disorder that produces several symptoms is________.
Sickle cell anemia causes hemoglobin, the oxygen - carrying molecule of red blood cells, to be misshapen resulting in disease. "H" is the normal hemoglobin allele and "h" is the allele for sickle - cell shaped hemoglobin. In order to get the disease, a person must have a recessive genotype (hh). Two people with normal red blood cells are carriers of the gene - they have m genotypes Hh.

a. What are the possible genotypes of the eggs the woman can produce?

- In 1967, a couple accused a hospital of switching their baby with another. DNA interpretation did not exist at this time so the hospital traced the blood types of the family in order to determine if a mistake was made. The mother had Type A blood, the father had Type AB blood, and the baby had Type O blood. Use the Punnett square to defend your answer to the following question: Did the hospital make a mistake and switch the baby? ____________arrow_forwardCan someone show me why this is correct? I will like to see the possible genotypes and phenotypes together that proves the answer.arrow_forwardGive typing answer with explanation and conclusion The father of Mr Spock, first officer of the starship Enterprise, came from planet Vulcan; Spock’s mother came from Earth. A Vulcan has pointed ears (P), adrenals absent (A), and a right-sided double heart (R). All these alleles are dominant to Earth alleles. The three loci are autosomal, and they are linked as shown: --P----- 15 mu -----A-------- 20 mu --------R— Here's the new twist: having Vulcan adrenals and a human heart is an embryonic lethal combination, which will distort the proportion of the various phenotypes. If Mr Spock marries an Earth woman and there is no genetic interference, what proportion (0…1.0) of their children will have the phenotypes: A. Human ears, Vulcan heart, human adrenals B. Human ears, human heart, Vulcan adrenals C. Vulcan ears, Vulcan heart, Vulcan adrenals D. Vulcan ears, human heart, human adrenalsarrow_forward
