Explanation:
Natural selection states that under naturally occurring circumstances, certain organisms may not survive. In other words, the weakest link is the one who doesn't make it.
Explanation:
A proto-oncogene is a<em> normal gene that usually can stimulate growth and differentiation but if it mutates can become an oncogene and cause cancer</em>. In order to test this gene, you can <em>activate it by promoting its mutation with a DNA amplification (like the one you did in the question) or a chromosomal translocation,</em> then you can observe it in a culture <em>if there's cell transformation you can confirm your hypothesis.</em>

Answer:
Frequency of heterozygous carriers of the allele in the entire herd is 
i.e 
out of 
Explanation:
It is given that a recessive allele pair produces a dwarf cow.
Let this recessive allele be represented by "t" and the dominant allele for tall height trait in cows be "T".
Given
Total population of randomly mating cows 
Total number of dwarf calves in the population 
Frequency of genotype "tt" producing dwarf calves is represented as 
in HW equilibrium equation.
Here
Frequency of recessive allele is equal to "q"
As per first equilibrium equation of HW,
Frequency of genotype "TT" producing dwarf calves is represented as 
in HW equilibrium equation.
As per HW's second equilibrium equation
Substituting the given values in above equation, we get -
Frequency of heterozygous carriers of the allele in the entire herd is i.e out of
