Question

ait th humans. In a cross between a sickle cell anemia? A. None B. 1/4 c. 1/8 ie ceil anemia and a mother who is heterozygous for the WHat is the probability that all of the four children are born with 1/16 8. According to Mendel's Law of Independent Assortment, which is CORRECT? A alleles of genes on different chromosomes assort randomly into different B. alleles of genes assort into gametes grouped according to how they were C. dominant alleles for one gene must assort into the same gamete as the D. domin gametes inherited originally. recessive alleles for another gene. dominant ant alleles for one gene must assort into the same gamete as the 9. The mutant alleles leading to Tay-Sachs disease are recessive because A. the mutation alleles always result in no protein being produced. B. the protein produced by the normal allele is sufficient for normal C. dominant alleles that cause a fatal disorder, such as Tay-Sachs disease, D. the mutations result in a protein that has normal function only if normal cellular function. cannot be inherited. protein also exists in the cell. cts as a dominant allele 10. The reason that the Mf allele in Marfan syndrome a is A. T HD he normal Mf allele does not normally produce a protein but the mutant allele does. B. The mutant ME allele blocks protein production (translation) from the normal Mf allele rotein that can damage ne

Explanation / Answer

8. A. Alleles of genes on different chromosomes assort randomly into different gametes, i.e. they are not dependent on each to express themselves.

9.b. The protein produced by the normal allele is sufficient for normal cellular function because tay sach's is heterezygous means it depends on both two carriers not one and hence if one is inherit from any parent it will affect the enzyme but won't cause the disease.
