Since there are four alleles, there are four different combinations of alleles possible in the gametes. Therefore, option C is correct. as there would be four different types of gametes possible in this system.
In a system where skin color in a certain species of fish is inherited via a single gene with four different alleles, the number of different types of gametes that would be possible can be determined using the principle of independent assortment.
The principle of independent assortment states that during gamete formation, the alleles for different traits segregate independently of each other.
Since there is only one gene involved in determining skin color in this case, we can assume that the alleles for skin color segregate independently as well.
With four different alleles for the skin color gene, let's label them as A, B, C, and D. Each individual gamete will carry only one allele. The possible combinations of alleles in the gametes can be calculated by multiplying the number of alleles for each gene together.
In this case, since there are four alleles, there are four different combinations of alleles possible in the gametes. Therefore, the correct answer is C) 4, as there would be four different types of gametes possible in this system.

Answer:
According to the punctuated equilibrium model, evolution occurs in spurts; species evolve relatively rapidly then remain unchanged for long periods.
Explanation:
The theory of punctuated equilibrium maintains that during most of the time of existence of a species it would remain stable or with minor changes, that is, in periods of stasis or periods of morphological stability, followed by rapid and abrupt events of evolutionary changes. This model was proposed by evolutionary biologist and paleontologist Stephen Jay Gould and his colleague Niles Eldrege. This theory includes the phenomena of stasis and the sudden or instantaneous appearance of forms in the normal process of speciation, that is, formation of new species.
Answer:
5.) The possible genotypes should be: RR RB BB ( if the could for the same proteins)
6.) Frequency of R: 0.5
7.)Frequency of R: 0.5
8.)Frequency of R: 0.375
Explanation:
5.) If R and B code for the different forms of the same protein then they are only a few possible out comes
6.) First calculate the total alleles in population
allele R= 40
Allele B=40
total allele = R+B= 40+40
=80
Now to find allele R frequency is:
(Total R alleles) / (Total allele in pop)
40/80=
0.5
7.)Calculate the total alleles
Alleles from for R
RR= 10
R=10x 2= 20
Multiply the value by 2 because there are 2 R alleles present in
RB=20
R=20
Number doesn't change there is only 1 R allele
Total R=20+20
=40
Alleles For B
BB=10
B=10×2
=20
Same thing here, two B alleles together so multiple by 2
RB=20
B=20
Total B= 20+20
=40
Total alleles in pop add
40+40
=80
Frequency of R
Total of R/Total Alleles
=40/80
=0.5
8.)Repeat the same thing in 7 but use different numbers
RR=10
R=10x2
=20
RB=10
R=10
Total R= 20+10
=30
Answer:
The correct answer will be-true
Explanation:
Mitochondria is a double membrane-bound organelle which is involved in the production of the energy molecules called ATP.
For the production and increase the productivity of the ATP molecules, the cell has modified the mitochondria by making the changes in the inner surface of the organelle.
The inner membrane possesses the enzyme called ATP synthase which synthesizes the enzymes. The inner membrane increases the infoldings called cristae which increases the surface area for the ATP production.
Thus, true is the correct answer.
