PLEASE HELP ILL MARK BRAINLIEST A biologist pollinates a true-breeding yellow flower with pollen from a true-breeding
red flower of the same species. All of the F, offspring are yellow. What question can be
answered with the F2 cross?
A. Are yellow flowers maternally inherited?
B. Are yellow flowers recessive and red flowers dominant?
C. Are red and yellow flowers codominant?
D. Is flower color polygenic?

A: When something is maternally inherited, it basically means non-Mendelian inheritance. Which means it doesn’t go by Mendel’s laws.
B: If the red flower would be dominant the offspring would have been red.
C: If yellow and red flowers would’ve been codominant, it would have been either yellow with red speckles, stripes, etc. or the other way around.
D: If the color would have been polygenic it would have been the phenotype being controlled by two or more genes.

This leads me to believe it is A.

Yes he thought they should be left to chance why, because he thought that was the best thing to do
