Miya Cross · Answer 1

all red

Explanation:

There is a case of incomplete dominance in the snapdragon since crossing red flower plant with white flower plant results in all pink at F1.

Assuming the allele for flower colour to be R. Red flower will be RR, white will be rr and pink will be Rr.

Hence, if a red flower plant (RR) is crossed with another red flower plant (RR), all the progeny will have RR genotype and will appear red.

The correct option is "all red".

Yoselin Ramirez · Answer 2

well, definitely all red, because in this case there is no white allele for the offsprings from the parents.
