Answer:

50%

Explanation:

This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.

Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.

If a woman takes HIV medicines during pregnancy and childbirth and her baby receives HIV medicines for 4 to 6 weeks after birth, the risk of transmitting HIV can be lowered to 2% or less. Most HIV medicines are safe to use during pregnancy, and don't increase the risk of birth defects.

In general, the infected mother should simply stay healthy and intake HIV medicines while she is pregnant.

Explanation:

Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km.
