Interrupted mating experiments were performed using three different Hfr strains (1-3). The three strains have different combinations of selectable markers. The time of entry for markers for each strain is shown is shown in the table given.

Hfr 1	Phe (5)	Trp (35)	Met (50)	Ala (52)
Hfr 2	Trp (2)	Val (12)	His (57)	Pro (87)
Hfr 3	Ala (10)	Met (12)	Val (37)	Phe (57)

Using the above data, predict the correct sequence of markers on the E. coli chromosome

In a particular species of mammal black hair (B) is dominant to green hair (b) and red eyes (R) are dominant to white eyes (r). If a BbRr individual is mated with a bbrrindividual the expected phenotypic ratio of the offspring is 1 black-red : 1 black-white: 1 green-red : 1 green-white. However, when you mate these individuals you find that the phenotypic ratio of the offspring is 6 black-red :1 black-white : 1 green-red : 6 green-white. What could account for this difference?
