Transcript

00:01 For question number one, modern humans have gene from which of the following species? the correct answer for this one is modern humans have genes from each of the following species, that is, netherals and denisovans.

00:26 The reason is that the study or the published in the journal science, it compared that the netheral genome to the genes of modern humans.

00:38 The comparison revealed that in some individuals up to 40 % or 4 % rather of the total genome was from the netheral origin.

00:51 The events that do not get pinned down therefore tend to be relatively recent starting with the migration of modern humans out of africa 60 ,000 years ago.

01:04 During which they interact with hominin relatives like nanderthals and denisovans that they met along the way.

01:13 They suggested that the science of gene flow from modern humans into nanderthals.

01:19 So the correct answer would be letter a.

01:23 For question number two, two evolutionary processes that may produce a client or clean in a human allele or trait are, this would be gene flow and genetic drift.

01:42 Take note that there are what we called as evolutionary clients.

01:52 It changes in the frequency of a genotype or a heritable phenotype over a geographical area and have long served as model system in evolutionary biology, clients arise and maintain via the interplay of genetic drift.

02:15 Gene flow across an environmental gradient, when clients are often interpreted as strong evidence of adaptive evolution, non -adaptive processes like genetic drift and gene flow may also aggregate or generate correlations, between the phenotype frequencies and also the environmental gradients.

02:38 Therefore, the correct answer for question number two would be letter a...
