Answer:
50% or 1/2. The result remains unchanged if the husband were to have G6PD.
Explanation:
For X-linked recessive inheritance, a female (XX) needs two recessive alleles to be affected while a male needs only one (XY). It is hypothetically assumed that the Y chromosome does not carry any trait.
Assuming the allele for the disease is represented by g, a woman whose father suffered from G6PD is a carrier for the disease with genotype . A normal man will have the genotype . When the 2 marries:
x = It thus means that 50% or 1/2 of their sons will be expected to have G6PD.
Now, assuming the husband has G6PD, the mating becomes:
x = 50% or 1/2 of their sons is still expected to have G6PD. The ratio remains unchanged.
The answer is that the criteria of classification change whith the improved understanding of organisms around us
Answer: -plants
-animal waste
Explanation:
Fossil fuels are the fuels which are generated after a long time taking geological process over the buried organic matter obtain from dead animals, animal dung and plants. The organic matter remain under the heap of earth crust under intense heat and pressure. The heat and pressure generate fuels which are valuable for the entire society as when they are burned they produce huge amount of thermal energy. These includes the crude oil like petroleum, natural gas and coal.
When a mutation has an effect that helps a species adapt to an environment, and specimens of both genders have it, it will end up taking over, causing evolution to gradually happen.
