We know that some people get fat much easier than others, even they eat the same amount of food and have the same lifestyle. The reason why some people are fatter than others is that our ancestors live in an environment where food supply is very limited and unstable (such as due to cold weather). Their bodies evolved so that excess nutrition is stored as fat, as a survival tool. Now there isn’t such a need for this function so a lot of people has evolved to adapt to the new environment which their bodies do not store excess fat. The conclusion is therefore, fat people evolve slower than thin people.

The Human Fertilisation and Embryology Authority are considering granting permission to UK scientists to fuse human DNA with cow eggs.

The stem cells from the embryos would be used for research into treating Parkinson's and Alzheimer's Diseases, and strokes.

Should UK scientists be allowed to create human-bovine embryos for stem cell research?

The recessive mutations b (black body color), st (scarlet eye color), and hk (hooked bristles) identify three autosomal genes in D. melanogaster. The following progeny were obtained from a testcross of females heterozygous for all three genes.


black, scarlet 243
black 241
black, hooked 15
black, hooked, scarlet 10
hooked 235
hooked, scarlet 226
scarlet 12
wild-type 18

What conclusions are possible concerning the linkage relationship of these three genes? What was the genotype of the female heterozygote? Calculate any appropriate map distances.
