A trade of chromosome segments among non-sister homologous chromatids happens and is referred to as crossing over.
Crossover happens while chromosomes, usually homologous times of the equal chromosome, spoil after which reconnect however to the specific quit piece. If they spoil on the equal location or locus withinside the collection of base pairs, the end result is an trade of genes, referred to as genetic recombination.
<h3>What are homologous chromosome?</h3>
Homologous chromosomes are made from chromosome pairs of about the equal length, centromere position, and marking pattern, for genes with the equal corresponding loci.
Thus it s well expalined.

The answer is; a layer of granite
This layer so granite is impervious hence is not porous. Due to its non-porosity, water cannot pass through it. These types of rocks are important in aquifers. When an impervious rocks sandwich a pervious layer or are below a pervious rock, an aquifer is created.
Geology is a branch of natural science that studies rocks, how they form, etc.
This field of study enabled us to know the age of Earth, the different layers that make up earth amongst many other things.

Recombinant DNA technology has also proven important to the production of vaccines and protein therapies such as human insulin, interferon and human growth hormone. It is also used to produce clotting factors for treating haemophilia and in the development of gene therapy. hope that helps
