Answer:
- Genotypes: 50% (Ww) and 50% (ww)
- Phenotypes: 50% will have white wings, and the other 50% will have yellow wings.
- Percent chance: 50% (heterozygous - Ww - yellow) and 50% (homozygous recessive - ww - white)
Explanation:
To answer this question, we make a Punnett square which looks like this:
You cross a heterozygous butterfly (Ww) and a homozygous recessive butterfly (ww), and it gives you:
Ww ww
Ww ww
As you can see from this Punnett square, 2 out of 4 have Ww, which makes it heterozygous and since they have the dominant W trait on them, they result to have white wings. The other 2 have yellow wings, since they have only w on them (recessive trait). Calculate percentages, you get 50% Ww and 50% ww.
People who have darker skin have more melanin which is a black or dark brown pigment in the skin. When we are out in the sun our skin produces more melanin, which helps our skin be more resistant in the sun. This is why we tan.

The correct answer is letter B, the age range of the skull is less than 10 years old. Teeth are also a form of bone that develop within the skull. Its structure helps archaeologists determine the age of fossils that they dug up from the soil. Children lack some prominent features compared to adults because their bodies are still growing and developing into maturity.
