What would happen if one of the chromosomes in a homologous pair failed to separate from its homologue at the end of metaphase I
Zepler [3.9K]

The correct answer is: daughter cells will have abnormal chromosome numbers and this condition is called aneuploidy.

Nondisjunction is the failure of homologous chromosomes (or sister chromatids) to separate during the process of cell division and consequently lead to aneuploidy. There are three forms of nondisjunction:  

• Nondisjunction in meiosis I (pair of homologous chromosomes unable to separate in meiosis I),  

• Nondisjunction in meiosis I (sister chromatids unable to separate during meiosis II), and

•  Nondisjunction in mitosis (failure of sister chromatids to separate during mitosis)

the allele for white fur is revessive and the allele for normal fur is dominant the frequency for the normal fur allele is 0.60.
Mariulka [41]

Answer:

36% of wolves have normal fur.

Explanation:

Given , the allele for white fur is recessive and the allele for normal fur is dominant

Let "N" represents the allele for normal fur and "n" represents the fur for white fur.

As per Hardy Weinberg's principle, the frequency for dominant allele is represented by "p"

Given ,

p = 0.60\\

Then frequency for dominant genotype will be "p^2"

So, Frequency for wolves with normal fur is

p^{2} \\0.60^2\\0.36

Percentage of the wolves with normal fur is

0.36*100\\= 36%

What is the difference between DNA, chromatin, and Chromosomes?
Serhud [2]
Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.

A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.

Under a microscope, chromatids look like little dots and chromosomes are lines.

D is correct. Newton's first law of motion states that an object in motion stays in motion. The orange is moving and then the tray stops making the orange move forward because of inertia. Hope this helps! ;)
