Bob and Sally recently married. Upon deciding to plan a family, both Sally and Bob find out that they are both heterozygous for cystic fibrosis, but neither of them has symptons of the disorder.
Biotechnology allow us to use living organisms or their processes for human needs or purposes. Currently this topic includes such general examples as cloning, stem cells (adult, umbilical cord, and
In Web searching (on Google, or Hotbot, or some such search engine) on the topic "Nature vs. Nurture.? find an interesting discussion or article related to it.
Suppose a gene in a chromosome is of type A or type B. Assume that the probability that a gene of type A will mutate to type B in one generation is 10^-4 and that a gene of type B will mutate to typ
Mendel is the father of modern genetics, but there are some genetic characteristics that cannot be explained by simple Mendelian genetics.
Using a Punnett Square, show how you would determine the probability that couple who were both carriers of an automsomal recessive disorder would have a child that would exihibit that disorder. Be s
A cattle rancher discovers that one of his bulls has a great deal of muscle mass but little fat, and wishes to create a pure-breeding stock with that trait. When he breeds the bull with wild-type co
In reference to biotechnology, what are some ethical or moral implications when we begin to shape or reshape human nature to our own design (i.e., choosing gender, eye color).
Unattached earlobes are a dominant trait. If A denotes the allele for unattached earlobes, and a denotes the allele for attached earlobes.
Frame-shift mutations occur when a nucleotide is accidentally omitted or added to DNA. Would a frame-shift mutation be more harmful if it occurred at the start of a gene or near the end of the gene?
Migration occurs at a constant rate between two populations of field mice. In one population, 65% of the population are white, in the other population, only 15% are white. What would you expect to h

What is the genotype of the F1 from a cross of a homozygous dominant x homozygous recessive.
Two white mice mate. The male has both a white and a black fur color gene. The female has only white fur color genes. The fur color of the offspring depends on the pairs of fur color genes that they

A female rabbit with hemophilia, rickets, and a tail was mated to a male rabbit that did not have hemophilia or rickets but lacked a tail. The F1 females were all wild type, that is, no having hemop
A couple is both phenotypically normal, but their son suffers from hemophilia. Draw a pedigree that shows the genotype of the 3 individuals. What fractions of their children are likely to suffer fro
What are the benefits of genetic engineering versus the potential risks? Do you think genetic engineering provides useful information for the scientific investigation of our natural world or do you
