Which of the following events is typical of meiosis but not of mitosis?

marin [14]

Answer:

D. the homologous chromosomes are paired AND the spindle is formed

Explanation:

Meiosis is the type of cell division that results in four daughter cells with each having a reduced number of chromosomes (by half). Both meiosis and mitosis occur in different stages including prophase, metaphase, anaphase etc but meiosis occurs in two series of division processes called meiosis I and meiosis II.

In prophase I of meiosis, homologous chromosomes, which are similar but non-identical chromosomes from male and female parents pair to form tetrad or bivalent. This pairing of homologous chromosome is unique and peculiar to MEIOSIS but never mitosis.

Matings between individuals from the two populations of Rhagoletis produce hybrid flies that appear to be healthy and have norma

Mama L [17]

<h2>The correct answer is : C.</h2>

Explanation:

According to the question, mating between two populations of Rhagoletis produce hybrid flies.
This means that the two population is present in the same habitat or locality, hence they are capable of coming in contact with each other and mate. Hence, the answer cannot be Habitat Isolation.
Mating produces hybrid flies. This is possible when the gametes (egg and sperm) of the two different populations are capable of capable of coming close to each other and undergoing fusion (fertilization). Hence, there is no Mechanical Isolation.
The zygote formed by the above fertilization is capable of developing into healthy hybrid flies with normal life span. Hence, Pre-zygotic Isolation is absent.
But the hybrid flies formed are sterile and not fertile, that is, they are incapable of producing viable gametes which can undergo fertilization and produce a new offspring.Therefore, the eggs laid by the hybrid flies hatch less often. Hence, there is existence of Reduced hybrid fertility.

Gene testing is foolproof since it scans the building blocks of humans. Please select the best answer from the choices provided.

Harrizon [31]

False

reason -

Gene testing is not full proof as there are possibilities of discrepancies in it based on the testing procedures used and the condition of sample. Since we human beings have the same genomic structure there are chances that our DNA may match with other people who do not share a heredity with our family. Basically statistical probability is used to determine probability of paternity, relationship of any kind etc. among two individuals . usually A 99% or higher percentage of probability is considered conclusive. and thus it gene testing can not be considered as full proof
