Cystic fibrosis is a genetic disorder in homozygous recessives that causes death during the teenage years. If 4 in 10,000 newborn babies have the disease, what are the expected frequencies of the dominant (A1) and recessive (A2) alleles according to the Hardy-Weinberg model?
Read DetailsUse this information to answer the next two questions. A population of a species of butterfly that mimics the wing color pattern of a monarch is growing at an annual rate of 12%. In August 2004, the population of this species in a certain locale was estimated to be 14,000.
Read DetailsGiven the image below, what evolutionary mechanism is occurring? Grey vs. White Mice Ratio Image Description A series of 3 images. In image 1 there are an equal number of white mice and grey mice. In image 2 a bird is seen taking a white mouse. In image 3 there is one remaining white mouse and 4 grey mice as the grey mice blend into their environment.
Read DetailsHere is a sketch of a replication bubble of the parent strands, as you might see in E. coli. Arrows indicate the direction of the replication forks. DNA Replication Image Description A visual representation of DNA replication where G and F represent the DNA before it is split. A, D, C, and E show the split DNA to be paired with the new sequence along with the arrows that indicate the replication fork and B represents the 5′ end of the strand. If letter (b) represents the 5′ end of the strand it is nearest, where is (are) the most likely place(s) to see the Okazaki fragments? (Remember this would be with the NEW strands being made to base pair with the parent strands that are shown.)
