Answer #1

Answer: Mutations in HoxD13 in humans can cause a genetic condition called synpolydactyly, in which people are born with extra fingers or toes that may also be fused together.

Gene expression is defined as processes that control the turning on or turning off of a gene. The Hox genes are a set of transcription factor genes that exhibit an unusual property: They provide a glimpse of one way in which gene expression is translated into the many different forms that animals (metazoans) exhibit. For the most part, the genome seems to be a welter of various genes scattered about randomly, with no order present in their arrangement on a chromosome—the order only becomes apparent in their expression through the process of development.

Huntington Chorea is a serious genetic disorder caused by a rare dominant allele (H) at an autosomal locus on chromosome 4. In some rural Michigan populations, the frequency of people diagnosed with the disorder is unusually high, about 0.05%.  Genetic work shows that the wild-type allele (+) mutates into H at a rate of 9.56x10-7mutations per gamete.Use these data to estimate how many children out of 10,000,000 births to parents without the disorder will have Huntington’s Chorea.

Sickle-cell anemia is caused by a single point mutation in the hemoglobin of human red blood cells. It is a recessive gene. People who have sickle cell anemia are homozygous recessive and suffer terribly from this disorder. Now I have stated in lecture that mutations are neither good nor bad. Rather it depends on how the mutation effects the survival of the species. If the mutation harms the survival of the species it is bad, if it helps the survival...

Huntington Chorea is a serious genetic disorder caused by a rare dominant allele (H) at an autosomal locus on chromosome 4. Individuals bearing an H allele produce a damaging protein that accumulates within the brain, leading to progressive loss of motor control and often to dementia. The disease often manifests itself later in life, and usually, Huntington Chorea victims die within 15 years after their neurological symptoms are diagnosed, but some people die before even being diagnosed. In some rural...

Sickle-cell disease (SCD) is a type of blood disorder caused by a mutation in the HBB gene. The mutation results in the production of abnormal red blood cells; these sickle-shaped cells are unable to efficiently transport oxygen to body tissues. Individuals must inherit two abnormal copies of HBB in order to have SCD. Heterozygous individuals, with one normal copy of HBB and one abnormal copy, are said to have sickle-cell trait (SCT); they generally do not experience problems with their...
