Question 2 1 out of 1 points
Some copies of the fourth chromosomes in a species of plant have extra DNA
attached to their telomere. The fourth chromosome also has two genetic markers.
A gene affecting flower size is 10 cM from the telomere, and it has two alleles
(normal flowers and small flowers). A gene affecting plant height is 20 cM from the
telomere, and it also has two alleles (normal height and tall).
You cross a true breeding tall plant with small flowers that also has the extra DNA
attached to the telomeres of both copies of the fourth chromosome to another
true bleeding plant that is normal height with normal flowers and normal
telomeres. All of the F1 progeny have normal flowers and are normal height, and
they are each heterozygous for the extra DNA on the telomere of the fourth
chromosome. If you cross the F1 progeny to tall plants with small flowers and
normal telomeres, what do you expect to observe in the F2?

Answer: Tall plants with small flowers are more likely to have extra DNA on
their telomeres than normal height plants with normal flowers.
Answers:
Tall plants with small flowers are more likely to have extra DNA on
their telomeres than normal height plants with normal flowers.
All plants with extra DNA on their telomeres will be tall with small
flowers.
Normal height plants with normal flowers are more likely to have
extra DNA on their telomeres than tall plants with small flowers.
None of the plants should have extra DNA on their telomeres.
All of the plants should have extra DNA on their telomeres.
