Tt. It's called homozygous recessive. In other words both variables would be lowercase
Cytokinesis is the meiotic event that would mostly cause Williams syndrome.
What is Williams syndrome?
Williams syndrome (Williams-beuren syndrome) is a rare genetic disorder. It is characterized by delays in growth before and after birth, varying degree of mental deficiency, short stature, and distinctive facial features that become pronounced with age.
The syndrome can be usually identified when the child is a baby or during early childhood.
Williams syndrome occurs due to loss/ deletion of genetic material of specific part of chromosome 7. There are 25 to 27 genes in the deleted region, and many believe that the loss of many of these genes is what contributes to the characteristic features of the syndrome.
A person with Williams syndrome is usually overfriendly, highly sociable, empathetic, with some anxiety relating to social events.
Therefore, Cytokinesis is the meiotic event that would mostly cause Williams syndrome.

Water is essential, you can only survive an average of 3 days without it. (some people have survived for longer though.)
Water is important for shipping and trade, because, ships. They go across water. Trade happens. It's hard to fit a lot in airplanes and you have to monitor it's weight slowly. Across land, it's also hard to fit a lot in random trucks driving across what was an ocean. (it would also be much more tedious) It's also one of the cheapest ways.
It is, I guess. There is a high demand for water, and a limited amount as well. It would also be profitable because you can get water easily, or something. (I don't really know for this one but the other two are true so I guess you can't select two so yeah.)
D should be the answer as they are no longer able to perform sexual reproduction without the other fish. Therefore, they would die off because they have lost the partner needed to reproduce.
Hope this helps!
I believe it's B. BRCA1 and BRCA2.
