Answer:

The correct answer will be option-C

Explanation:

Non-disjunction is the failure of the separation of the chromosomes during the separation phase of the division that anaphase I and anaphase II of meiosis.

The non-disjunction takes place during meiosis which takes place in the gamete formation.

A condition which develops from the non-disjunction with one extra copy of the Y chromosome is known as 47, XYY condition or Klinefelter syndrome.

This extra copy of the Y chromosome takes place when the chromosome separation failure takes place during anaphase II of meiosis II. This separation creates one extra copy of the chromosome.

Thus, Option-C is the correct answer.

aivan3 [116]

Answer:

The immature prefrontal cortex lead to  conflict for teens because the teenagers when they try to use the frontal lobe for reasoning, they tend to overdo it and then giving their brain much work to do. This leads to conflict in teens.

Explanation:

In teens, the prefrontal cortex is immature and develops until the mid-20s of their age. It covers the front part of the frontal lobe. As a result of the immaturity of the prefrontal cortex in teens, they do not think or make decisions like that of adults. When they try to overdo with their immature prefrontal cortex, they end up in conflicts.

Explain how corn can be used as an example of Mendel's law of independent assortment.
MatroZZZ [7]

Answer:

Mendel's law of independent assortment states that the genes are separated and inherited independently of each other into the gametes.

The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.

Single corn may contain 800-1000 kernels which may have different shape, texture, structure et cetera as result of independent assortment, that is, each kernel receives alleles of genes independent of each other.

For example, a gene responsible for the texture of kernel would be inherited independently of the gene responsible for the color of the kernel.
