Answer:

This definition suits that of "HOMOLOGOUS CHROMOSOMES"

Explanation:

Homologous chromosomes are similar pairs of chromosomes i.e. in length, gene positioning and centromere location (one from each parent) but not identical. Homologous chromosomes are not identical in the sense that, alleles on each pair may be different, resulting in genetic variation of the offspring.

Using humans as a case study, a karyotype (pictorial display of chromosomal arrangement) shows the complete set of chromosomes, which has two complete set (diploid). Each human cell contain 23 pairs of chromosomes, with each pair contributed by each parent i.e. 46 chromosomes in total. Every chromosome pair represents a set of homologous chromosome.

Answer:

HOMOLOGOUS CHROMOSOMES are chromosome pairs (one from each parent) that are similar in length, gene position, and centromere location.

Explanation:

A Homologous chromosome is a two sister chromatids attached with cohesions to form a tetrad. It has the same genes but may have different alleles for each trait. They are similar in nature and not identical in nature.

E.g, A Human cell has 23 pairs of chromosomes, with a total of 46 chromosome per cell. Each chromosome pair stands for a set of homologous chromosomes.

Southern Texas

Explanation:

The Wind pattern often is represented by the westerlies, which are the winds that flow in the northern latitude of the world. The humidity level in this zone varies from 10-20%, since we are in the desert we do not have much humidity, the solar intensity is high, often found in the 9-10 uv range, it is not advised to spend more than 10 minutes on direct sun without solar protection. We have the Rio Grande to the south and some spare mountains.
