I have a take home test but this woman is killing me!!!!
1. Tongue rolling is an example of variation which is:
(a) Continuous and genetic
(b) Continuous and environmental
(c) Discontinuous and environmental
(d) Discontinuous and genetic
2. All of the following are true for red-green color blindness and hemophilia EXCEPT:
(a) Males cannot be carrier of these traits
(b) They are determined by recessive alleles
(c) More common in males than females
(d) They are examples of sex linkage
3. Houseflies show resistance to DDT is an example of __________ selection
4. _________ selection is also known as selective breathing since man does the selecting.
5. In humans one pair of the 23 pairs of homologous chromosomes is called the __________ chromosomes.
6. In the fruit fly Drosophilia, grey body color and black body color are found. Two grey bodied flies mated and produced 712 flies of 526 are grey and 186 are black.
(a) what is the genotype of the fly
(b) How many of the grey flies in F 1 would you expect to be homozygous (pure breeding)
