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.
A pathway that tends to slow down a process is called a negative feedback loop.
<h3>What we know about these loops. </h3>
- These loops function to reduce the rate a which a process occurs.
- Being a feedback loop means that they take in stimuli from the environment of the cell in order to affect the rate of production of a compound.
- A negative feedback loop will activate when the concentration of the compound being produced is too high.
- In response, the negative loop will reduce the rate of production temporarily.
Therefore, we can confirm that a pathway that tends to slow down a process is called a negative feedback loop.

The fever of unknown origin, or the FUO can be defined as the condition when the body temperature of a person is at 101 degree Fahrenheit for at least a period of the three weeks without any observable underlying cause. The most common causes of the FUO includes, infections (such as Lyme disease, tuberculosis), malignancy (such as leukemia), inflammation (such as inflammatory bowel disease), and alcohol or drug abuse.
