Female with Short Hair Male with Long Hair Male with Short Hair Which of the following is a reasonable claim that the scientists can make based on the information in the pedigree? A The phenotype for long hair is dominant to the phenotype for short hair because there were fewer offspring with long hair than with short hair. The phenotype for long hair is recessive to the phenotype for short hair because only individuals with the insertion mutation have long hair. The phenotype for long hair is dominant to the phenotype for short hair because two copies of the allele without the insertion mutation are necessary to show the short hair phenotype. Toffspring.

Given what you read about the human genomein Chapter 13, would you predict that most mutations in humansare harmful, beneficial, or neutral?
Some critics have warned that the use of gene therapy to correct genetic disorders will affect the course of human evolution. Evaluate this criticism in light of what you know about population genetics and evolution, distinguishing between somatic gene therapy and germ-line gene therapy.
Now that cloning is possible, should it be used to clone animals that are near extinction? What are the possible ramifications of this when it comes to genetic diversity and size of the gene pool?
Genes that are duplicated within a genome and later diverge in function, such as the RNASE1 and RNASE1B genes in a species of monkeys, are described as -Derived genes -ancestral genes -orthologous genes -paralogous genes
Consider a recessive condition where 40% of the affected individuals pass away by the age of 10 but those that survive to adulthood are just as likely to have children as the general population. What must the new mutation rate be if the incidence of the disorder is 1/10,000 to maintain a consistent incidence across generations? Answer format: Fraction - #/#
The technique known as DNA sequencing enables researchers to determine the DNA sequence of genes. Wouldthis technique be used primarily by transmission geneticists, molecular geneticists, or population geneticists?
Before the advent of recombinant DNA technology, why was it so diffcult for geneticists to map human genes using pedigrees? How did recombinant DNA technology help move things forward?
Recently, scientists have identified a mutation that is found at high frequency in Finnish populations, located in northern Europe where the winter is very cold. This mutation is believed to be a “cold sensitive” allele that warns people of extreme cold temperatures. Could this allele have undergone a “selective sweep”, if it had suddenly appeared in this northern population of humans? How would such a selective sweep be detected with genome data?
Are the following examples a description of genetics at the molecular, cellular, organismal, or populational level? A. People with cystic fibrosis have lung problems due to a buildup of mucus in their lungs B. The mutant CF gene encodes a chloride transporter that doesn't transport chloride ions very well. C. A defect in the chloride transporter causes a salt imbalance in lung cells.

As genetic testing becomes widespread, medical records will containthe results of such testing. Who should have access to thisinformation? Should employers, potential employers, or insurancecompanies be allowed to have this information? Would youfavor or oppose having the government establish and maintain acentral database containing the results of individuals’ genomescans?
You are discussing with some of your bio major friends who have not taken Genetics and your non-bio major friends about how characteristics such as blue eye, light skin pigmentation, and light hair color, derived from a mutation that occurred about 10,000 years ago in Europe. Your friends are not very happy that you used the word mutation to describe the origin of human characteristics associated with light pigmentation. At that moment you only recall that green eye, fair skin and red hair in Neanderthals was due to other alleles and you mention that to them as an example of genetic determinants in species of the genus Homo. They are not convinced of your choice of the word mutation. Then you remember part of one of the papers that you read for Minicourse 5 regarding the OCA2 allele. “OCA2, homologous to the mouse pink-eyed dilution gene, encodes the human protein P, an integral membrane protein involved in both the transport of tyrosine and that helps in the regulation of…
