The graphs below show antibiotic production from the same population of bacteria, grown in two different
environments-high glucose and low glucose.
Number
of
organisms
HIGH GLUCOSE
LOW GLUCOSE
Amount of antibiotic produced
If you calculate the heritability of antibiotic production for this population of bacteria when grown in low glucose
compared to when it is grown in high glucose, the estimated heritability value
Incorrect
will be smaller in the low glucose than in the high glucose.
will not be possible to estimate because you don't know the genotypic variation.
will be larger in the low glucose than in the high glucose.
will be the same in both environments.

As you sift through the 10 or so coconuts on the ground you find two that aren’t hairy. What can you conclude about the genotypes of the two parent trees?arrow_forward
