Answer:
F(M) = 0.7 F(N)=0.3
Explanation:
We need to take into account that individuals NN and MM only N or M aleles respectively while MN gives just half of the allelic contribution for each. With this in mind we have the following probabilities for getting each of the alleles: MM => p(M) = 1.0 and p(N)=0.0
MN => p(M ) = 0.5 and p(N) = 0.5
NN => P(M) = 0.0 and p(N) = 1.0
With this we can calculate the frequencies of the M and N alleles in the population with 100 individuals using the following formulas
For f(M):
The frequency of the M allele is 0.7
For f(N):
The frequency of the N allele is 0.3
Answer:
Natural selection
Explanation:
Natural selection is a process where some organisms are able to reproduce more and survive better due to the presence of beneficial genetic traits in them. The other organisms of the same population that lack these traits are not able to survive and reproduce in the same way. The bacterial having drug resistance are able to survive in the presence of drugs in the surroundings. These bacteria will reproduce more and leave more progeny. Over the generations, the proportion of the bacteria with drug resistance will increase. This represents an example of natural selection.
Yeast
(e.g fermentation is the process by which yeast converts glucose into alcohol and carbon dioxide, yeast also makes bread rise)
Gradient is the d. dinner membrane of chloroplast
As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -liquid.
