The correct location on a place on the Earth is shown by using the meridians and the parallels.
The meridians are the vertical lines that are stretching from one pole to another, while the parallels are the horizontal lines that start from the Equator and make imaginary circles around the Earth in northern and southern direction. With the use of this two, we have the longitude and latitude at hand, so with a basic knowledge of cartography, every place can be located precisely on the surface of the Earth.
Answer:
Homozygous.
Explanation:
As the exercise describes, when the first 22 chromosomes contain hundreds of genes in the same positions and sequence. If the code of the gene from one parent is exactly like the code on the same gene from the other parent, the gene pair is called homozygous. This is a genetic condition in which an individual has inherited the same DNA sequence, for a particular gene, from both their biological parents, therefore, having two identical copies of a particular gene.
The correct answer is random selection.
Random selection refers to a process in which a sample or group of participants for a research study are randomly drawn from the entire population the researcher has access to. The main strength of using a random sample for a research study is that biases are avoided and the findings obtained are more representative of the population as a whole.
