Answer:
Option C. A person inherits chromosomes from just one parent.
Explanation:
Genetic disorders or diseases that are caused by errors that occur during meiosis is called down syndrome. It is also known as trisomy 21. In this disease the person inherits one extra pair of chromosomes from one of the parent i. e. Father or mother.
Answer:
B
Explanation:
<em>The correct answer would be that in metaphase 1 twice as many chromosomes line up along the middle of the cell as in metaphase 2.</em>
Metaphase generally involves the formation of the metaphase plate and the alignment of chromosomes at the equator of the cell.
<u>At metaphase I, chromosomes align as homologous pairs as opposed to metaphase II where chromosomes align at the equatorial plate singly. It thus means that twice as many chromosomes line up at the equatorial plate in metaphase I when compared to metaphase II.</u>
The correct option is B.
Answer:

Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
