Question
1. Why must karyotypes be made from cells in metaphase of mitosis? What are two reasons that knowing the karyotype of an organisms cells can be useful?2. In two paragraphs describe three major ways the process of mitosis differs from the process of meiosis.
3. In two paragraphs contrast sexual and asexual reproduction in three ways. Then describe a positive and a negative aspect for each.
Please answer all three questions if possible, and thanks so much!! You're a life saver. 1. Why must karyotypes be made from cells in metaphase of mitosis? What are two reasons that knowing the karyotype of an organisms cells can be useful?

Explanation / Answer
1. Karyotypes be made from cells in a metaphase of mitosis because the chromosomes are better visible and aligned in a particular manner and during mitosis the chromosomes are only duplicated no more complex so it is easy to take a karyogram during metaphase.
Karyotype is the representation of shape, number and size of chromosome of an specific organism.
Importance of karyotypes :
a. Detect the species of on the basis of karyogram
b. Determine the chromosomal disorder of an individual by observing the karyotype of an individual.
2.
Mitosis
Meiosis
3.
Sexual reproduction
Asexual reproduction
Advantage
Sexual reproduction:
It leads to survival of the specied, due to different factorslike environment, mutation, adaptation
It also removes bad genes from population
Asexual reproduction
Rapid increase of population, has ability to produce a large no of offspring in a very less time
Disadvantage
Sexual reproduction
Produces less no of offspring, and more time required
Asexual reproduction
No genetic variations so leads to extinction
