Answer:
F=dominant, 6 fingers
f= reccessive, 5 fingers
Ff= 6 fingers( contains dominant gene)
if you combine Ff and Ff you get:
25% FF (6 fingers)
50% Ff (6 fingers)
25% ff ((5 fingers)
so only 25% will have 5 fingers (normal)
Answer2:
Dominant=normal hearing
Recessive= deafness
If one parent is RR and the other Rr, the offspring will be:
50% RR
50% Rr
so all the offspring will have normal hearing, and there is 0% of deafness.
Hope it helps!!
A plant cell would be a cell wall and for an animal cell it would be the cell membrane.
Answer:
<u>ligase</u>
Explanation:
Short segments of newly synthesized DNA are joined into a continuous strand by <u>ligase</u>
Answer:
The correct answer is - true.
Explanation:
Type I error occurs when the alternate hypothesis is accepted though it is false. A type II error is the failure to reject a false null hypothesis or an alternative hypothesis is rejected even though it is true.
For instance of type II errors: a blood test designed to detect the disease failing to detect the disease in a patient who really has the disease. In the given case vaccination not approved even though reduce the risk of contracting the HIV virus.
Thus, the correct answer is - true.
1. The population is under selection pressure from predators
<span>2. Hey now, no population is ever at H-W equilibrium: </span>
<span>mutations happen </span>
<span>immigration and emigration can occur </span>
<span>the population is not huge, which means that genetic drift can happen </span>
<span>mating is not completely random -- a rat is more likely to mate with someone local than with someone living in Paris, France. </span>
<span>b) The small rats will be selected for (assuming there are predators in this ecosystem that are less likely to look in bushes, and further assuming that the small rats do not have reduced fertility by dint of being small) </span>
<span>This is "directional selection" </span>
<span>c) I would expect the "smallness" allele frequency to increase in this population over time, and the "normal size" allele frequency to decrease.</span>
