Question #3:
In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would
transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming
there was just one gene conferring gametophytic obligate apomixis, and that the two parents are
inbreds, what would be the consequences of such a cross if:
a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non-
apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic
and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female
first (left side) in the parental cross.
b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non-
apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic
and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female
first (left side) in the…
Question #5:
Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The
genes show independent assortment. Recessive alleles at both loci are required for the facultative
apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C.
At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype.
A facultative apomict male, capable of producing viable pollen, was crossed with a sexually
reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic
ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following
temperatures*:
a) 15°C?
b) 25°C?
*for full credit, show crosses and genotypes where appropriate. Remember to position the
female first (left side) in the cross.
