When the fish is put into fresh water, suddenly the concentration around them is very low and the water potential is extremely high. Water will now move from the relatively high water potential in the water to the relatively low water potential in the cells, the cells start to burst and the fish dies.

A population of dogs can be either brown or black; the black allele (B) has complete dominance over the brown allele (b). Given

Marat540 [252]

Answer:

The frequency of individuals with the dominant phenotype is 0.83.

Explanation:

We are provided with:

Black allele has completed dominance over brown allele

T. no of dogs (dominant)= 2000

No. of black dogs (dominant) = 1660

From Hardy-weinberg equilibrium
