Answer: C
It can’t be A or D straight away due to the fact RR cannot be produced with only 1 R in two parents. And B cannot be correct for the same reason.

anygoal [31]

Answer:

A basic and a non-invasive test done in pregnancies during the course of 28 weeks of gestation is termed as a fetal non-stress test. It is termed non-stress as no stress is imparted on the fetus while performing the examination. The main objective of the test is to determine the fetus's heart rate at the time of its movement.  

In the test, it can be seen that the heart rate of the fetus gets increased each time it moves, which shows that the baby is healthy as the heart rate goes up when it moves and goes down during its resting stage. The principle behind the test is that for proper well-being of the fetus, sufficient oxygen is needed and heart rate should come in normal ranges.

Explain how the independent alignment of homologs, and also crossing-over during the first meiotic division, each contribute to
BartSMP [9]

Answer: Homologous chromosomes are randomly distributed to daughter cells, this means different chromosomes segregate independently of each other. And they exchange segments of DNA during crossing over. This recombination creates genetic diversity because genes from each parent are exchanged.

Explanation:

Meiosis is a type of cell division that produces gamete cells, which are sex cells (egg and sperm)

Chromosomes that form a pair and are found together are called homologous chromosomes, and they are inherited from each parent. During prophase of meiosis I, the homologous chromosomes exchange segments of DNA in a process called crossing over. This recombination creates genetic diversity because genes from each parent are exchanged. <u>It results in new combinations of genes on each chromosome.</u>

After that, during the anaphase of meiosis I, the two chromosomes line up on the equatorial plane of the cell. Then, they are separated and each will go to a new daughter cell. So homologous chromosomes are randomly distributed to daughter cells, <u>this means different chromosomes segregate independently of each other.</u>

Why should deepwater shrimp on different sides of the isthmus have diverged from each other earlier than shallow-water shrimp?
Nataly_w [17]

Answer:

Reproductive isolation occurs faster in deep-water shrimp than shallow-water shrimp.

Explanation:

Though in the same territory, the blockage caused by the isthmus would quickly and permanently isolate shrimps living in the deeper parts of the water, thus making them unable to breed. This situation would then caused lack of gene flow within the deep-water shrimps , and the emergence of new species that are genetically different (diverge) from one another

The shallow-water shrimp, on the other hand, experience minimal isolation due to the shallowness of water, and could still breed with one another. Thus, they experience a relatively lower reproductive isolation
