B: A mutation in one of G5W's parents, during gamete formation, created an X-linked dominant disease allele.
You need to analyze the sex gametes.
Boys are XY
Girls are XX
If you have an X-linked dominant disease you need only one affected X gamete to have the disease.
The mother has XX' where X' is de affected and reproduce with a healthy man XY and breed unhealthy boys, but because of the heterozygous gametes you could also have healthy ones XX and XY
I'm pretty sure it's deposition because the sediments in the water(soil) are building up on the rock.
An enormous cloud of gas and dust that contracts due to gravity and forms stars is called a nebula.
These would be any cells that reproduce asexually, like bacteria
