The sequence of the genes will be ABCD, abCD and abCd, abcD.
Full question is attatched below.
<h3><u>Explanation:</u></h3>
The genes in the chromosomes are denoted as the sequence of genes present in a single chromatid of a particular chromosome. Thus, the genes here in this question are to be mentioned as ABCD and not as abab.
Crossing over is the process by which the homologous pair of chromosomes do pair up in the Prophase 1 of meiosis 1 division and they exchange a particular part of their DNA with each other. This leads to exchange of genes between the homologous chromosomes, which will form different gametes in near future. This brings about a variation between the offsprings of same individuals.
Here the d gene of the two chromosomes are getting exchanged.
So the chromosomes will become ABCD, abCD and abCd, abcD respectively.

Answer: </u></h2>
<u>Erosion:</u> is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.Erosion is the opposite of deposition, the geological process in which earthen materials are deposited, or built up, on a landform.
Most erosion is performed by liquid water, wind, or ice . Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.
<u>Public domains:</u>VegetationThe simplest and most natural way toprevent erosion is through planting vegetation. Plants establish root systems, which stabilizes soiland prevents soil erosion. Geotextiles: Using geotextiles is an effective method because it also stabilizes soi

The use of sandbags is a simple, but effective way to prevent or reduce floodwater damage. Properly filled and placed sandbags can act as a barrier to divert moving water around, instead of through, buildings. ... Tied sandbags are generally easier to handle and stockpile.
