Answer: The correct answer is D. Autosomal chromosome.

An autosomal chromosome is a characteristic which arises from genes which are located in the chromosomes that are not gender-determining. The autosomal trait does not depend on sex.
Its function is to pass genetic traits from mother and father to the child. Traits can be recessive or dominant. When someone has green eyes we say he/she is recessive trait and not dependent on the sex of the child.
In each cell, people have 22 pairs of autosomes plus two sex chromosomes which Y and X in male and XX in the female.

Which process helps make meiotic vlcells genetically different and occurs during prophase 1 ,but not during prophase 2

Answers

So basically in Prophase 1 you will get a synapsis (pairing) between homologous chromosomes. Followed by this you have what is called the crossing over stage, this is where different sections of the chromosomes are exchanged.

When it comes to cytokinesis in meiosis II, you will have four genetically unique haploid cells, that will have a random combination/mixture of the parental and maternal genes

The germ theory of disease was established by Lois Pasteur. He conducted experiments to prove that fermentation is the result of micro-organisms growing on sugar. It proved that spontaneous generation was wrong. Spontaneous generation was the belief that the action of God could cause living organisms to grow from non-living things. Pasteur also proved that micro-organisms from the air were the cause of infectious diseases. Three of his daughters died from infectious diseases. Pasteur proved that these diseases were caused by germs floating in the air. He also helped develop vaccines to help prevent some of these diseases.
