An animal has a diploid chromosome number of 60. Suppose that the first meiotic division of a germ cell is normal, but a single

dyad in one of the two daughter cells undergoes non-disjunction in meiosis II. How many chromosomes would be present in each of the four gametes that result from that meiosis?

Answer:

Two gametes end up with 30 chromosomes, one gamete will have 31 and one will have 29.

Explanation:

During meiosis, a single diploid cell divides into four haploid cells with half the chromosome number than the parent cell.

During meiosis I, homologous chromosomes separate and the chromosome number in the two daughter cells goes down by half. During meiosis II, the "sister" chromatids separate, and the chromosome number in the respective daughter cells remains the same.

Non-disjunction of a single dyad in meiosis II causes that one of the daughter cells will have an extra chromosome, and another will be lacking one. The two other gametes will be normal.

I drew a simple example of what would happen during meiosis of a 2n=4 cell if there was non-disjunction in a single dyad during meiosis II.

Living and nonliving things in an ecosystem interact with each other; on the other hand, plants use energy from the sun.

Explanation:

The ecosystem is an interaction circumstance between the living and non - living things which exists in an environment and has an impact on its too. The essential source of energy to this ecosystem is the solar energy coming from the sun.

But the energy from the sun could only be taken up by the plants and being used in photosynthesis to produce food and oxygen which required by other living things of the ecosystem. This essentiality is exclusive of the plants.

The Florida Panther is the brown and gray species the puma family. For years a small population of the panther lived in the wood
Tasya [4]

The correct answer is - a. It will reduce genetic diversity.

The pumas that live in Florida, also known as the Florida Panthers, will have a much reduced genetic diversity. The reason for this is that the population is very small. It also lives in the same area, where the living conditions are the same. The genetic pool is very small, and the breeding is going on between individuals that have the same traits, and are also relatively closely related, as the mating occurs between the second or third generation that came out form the same parents. That will result in a very reduced genetic diversity, so the Florida Panther will remain the same if the conditions do not change drastically, or these an invasion of pumas from the west into their territory.
