In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of allele a is 0.2. what is the
Allushta [10]
The Hardy-Weinberg equation is as follows:
( {p + q})^{2}  = 1
{p}^{2}  +2pq +   {q}^{2}  = 1
Where:
(convert all % to decimals)

p= homozygous dominant
q= homozygous recessive
pq= heterozygous

While you did not specify whether the 0.2 frequency was for dominant or recessive, we can still figure out the answer.

Using the 1st equation, we can solve for the other dominant/recessive frequency:

1-0.2=0.8

Meaning that:

p= 0.8 & q=0.2

If the heterozygouz frequency is 2pq, then it becomes a simple "plug & chug" sort of approach.

2(0.8)(0.2)= 2(0.16)= 0.32

So, the heterozygous frequency would be:
0.32

Hope this helps!

How can a refute hypothesis lead to a new investigation
IrinaVladis [17]

A refute hypothesis is a hypothesis that has been refused, not accepted.

When a hypothesis is refused, the scientists that proposed it will try to correct it or to create a similar more applicable one, and that is how new investigations could occur in this case.


Hope it helped,

Which step can occur even more rapidly by PCR?a. target DNA removed from cells and isolated b. cloning host treated with calcium
lisabon 2012 [21]

Answer:

E. Gene is amplified by multiplication of cloning host

Explanation:

PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.

As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number.

Each P1 parent of a monohybrid cross has completely identical genes<br> ture<br> false
lawyer [7]

Answer:

False.

Explanation:

Monohybrid cross may be defined as the cross done by taking the single character at the time. The monohybrid cross explains the concept of dominance and law of segregation.

The P1 parent of monohybrid cross doesnot have completely identical genes. This can be explained by the cross shown below:

Parent         Tt           ×       tt

Gamete         T  t           ×     t

Here, the parents are not identical.  

Thus, the answer is falsi.
