You are running a nursery for garden peas at baton rouge, and you have two pure-bred garden pea strains: yellow wrinkled [yyrr] and green round [yyrr]. you know that yellow is dominant to green, and also that round is dominant to wrinkled. one customer dropped by and asked about one particular pure-bred strain, yellow round [yyrr]. you promised to that customer that you could generate that strain next year through the following breeding experiments.
i. crossing pure-bred yellow wrinkled with green round
ii. self-crossing f1 progeny
iii. screening pure-bred yellow round among the f2 progeny

what is the genotype for f1 progeny?

a. yyrr
b. rryy
c. yyrr
d. yyrr
e. none of the above

Two male mice, which we will call male a and male b, are both phenotypically normal. male a was from a litter that contained half phenotypically normal mice and half dwarf mice. the mother of male a was known to be homozygous for the normal igf2 allele. male b was from a litter of eight mice that were all phenotypically normal. the parents of male b were a phenotypically normal male and a dwarf female. male a and male b were put into a cage with two female mice that we will call female a and female b. female a is a dwarf and female b is phenotypically normal. the parents of these two females were unknown, although it was known that they were from the same litter. the mice were allowed to mate with each other, and the following data were obtained: female a gave birth to three dwarf babies and four normal babies. female b gave birth to four normal babies and two dwarf babies. which male(s)mated with female a and female b? male a with both females male a with female b, and male b with female a male a with female a, and male b with female b could not be determined male b with both females
