From memory
what is the formula for X?? (X is Chi). Remember to
include the correct Greek letter (not Chi, the other one).
b) You did a monohybrid cross looking at flower color, purple or white. How many degrees of freedom
do you use on the X2 table?
In which kind of cross would you expect to find a ratio of 9:3:3:1 among the F2 spring
A) Monohybrid crossB) None of these choices is correctC) testcrossD) Dihybrid cross
An egg parent with type A blood is claiming that a person with type AB blood is the sperm parent of the child who is type B.
1) Could this person be a sperm parent of the child? Show the possible crosses.
2) Assuming that this person is sperm parent of the child, what must be the genotype of the egg parent?
