#6:  knowledge in genetics

Tall (A) is completely dominant to short (a), and red (B) is completely dominant to
white (b) in a certain species of flowering plants. If a testcross into ardihybrid (aabb
x AaBb) results in a 1 tall and white :1 short and red phenotypic ratio, then:
(Read each of the following statements carefully. Select all of the statements below
that are true (that you agree with). Leave any statements that are false (that you do
not agree with) un-selected.)
O the two genes could be very far apart on the same chromosome.
the dihybrid parent represented two genes that are independent and in trans
configuration.
half of the progeny are from segregation alone while the other half is from
crossing over and then segregation:
Ce dihybrid parent represented two genes that are linked and in cis
configuration.
U all of the progeny are parentals; no recombinants resulted from this cross.
