An autosomal recessive disease has an incidence of 1/10,000. What is the approximate frequency of heterozygote carriers for this

goblinko [34]

Answer:

Option B

Explanation:

Given

Number of incidences or frequency of an autosomal recessive disease $= \frac{1}{10000}$

As per Hardy Weinberg's equation, frequency of a recessive genotype is $q^{2}$

$q = \sqrt{\frac{1}{10000} }\\ q = \frac{1}{100}$

As per first equation of Hardy Weinberg's -

$p+q=1$

so ,

$p = 1-q\\p = 1-\frac{1}{100}\\p = \frac{99}{100}$

$p^2 = (\frac{99}{100})^2\\p^2 =\frac{9801}{1000}$

As per second equation of Hardy Weinberg's -

$p^{2} + q^{2} + 2pq=1$

Substituting the given values in above equation, we get -

$\frac{9801}{10000} + \frac{1}{100} + 2pq=1\\2pq = 1-(\frac{9801}{10000} + \frac{1}{100})\\2pq = 0.99%\\OR[tex]2pq=1$ %

$2pq = \frac{1}{100}$

Hence, option B is correct.

In this experiment, how many chromosomes were present when meiosis i started? 2. in this experiment, how many nuclei are present

wariber [46]

1. The answer depends on your picture.
DNA is packed and condensed with proteins in the form of chromosomes.

Since the process of division is going to start that means each chromosome will have an X shape. They had the DNA content copied once (in the S phase). The original, plus the copy created, form the X.

You just have to count the number of X's in the picture.

2. The answer is 4 nuclei.
Since the process of division happening is meiosis, that means that four new cells will be originated from a cell that's dividing.
So, four new cells each one with a nucleus, that means 4 nuclei in total.

If this was mitosis, only 2 new cells would be formed which means 2 nuclei

3. The number of chromosomes depends on your picture/exercise.

The answer would be half of the number of chromosomes that you started in the meiosis 1.
This time, chromosomes won't have an X shape since the copies were separated. At the end of the process, each chromosome has just one chromatid.
