PLEASE EXPLAIN Darwinism

Heterochromia iridium is a recessive autosomal condition in hurnons in which the colour of the iris of one eye is different from the colour of the other eye. Consider that in a human population, in a survey of 5000 people, two people were found to have heterochromia. Also, consider that the population is at Hardy-Weinberg equilibrium at this locus. Based on this information, answer the question:
(a) Assume that mating occurs at random with respect to this character. What frequency of the matings in this population will be between heterozygous individuals and homozygous dominant individuals?

What is the importance of taxonomy in biological studies? Describe any two cytological approaches that enable us to meet the objectives of taxonomy.

In 2000 and 2004, a University of Michigan palaeontologist discovered two well-preserved skeletons of a now-extinct species, about 47.5 million years old. He named this newly-discovered species Maiacetus inuus. He described them as skeletons of early whales that actually lived on land, before whales had evolved to become entirely aquatic like modern-day whales.

a) Explain how you would use the fossil record as evidence to suggest that Maiacetus inuus is an evolutionary ancestor of the modern-day whale.

b) Assume that traces of preserved DNA were discovered inside of the Maiacetus inuus fossils. Explain how this DNA could be used to show an evolutionary relationship between Maiacetus inuus and modern-day whales.

"Closely related organisms may be found in widely separated areas". Explain this phenomenon by giving a suitable example.

Examine the cladogram of whales and their ancestors presented in this video. Note that this diagram does NOT show modern whales evolving from any specific fossil form, but form the common ancestors of known fossil species and modern animals. Discuss the important difference between this view of evolutionary history, and the old view, which often attempted to identify specific fossils as the ancestors of a living form.

What is the African indigenous explanation of where humans originated from?

Consider a population with two loci (A, B) each with two alleles (A,a and B, b). Which of the following represent expected frequencies for particular haplotypes, if the frequency of allele A = 0.5 and the frequency of allele B = 0.7, and alleles are combined at random across the two loci?


ab = 0.25 and aB = 0.25


AA = 0.25 and Ab = 0.3


AB = 0.35 and bb = 0.09


AB = 0.7 and Ab = 0.125


Ab = 0.15 and aB= 0.35
