To know what happens here, you need to analyze the alleles.
If the father is color blind and the daughter is not, you can suppose that is a recessive allele.
You can tell she is a carrier only, and because we received one sexual allele from each parent. If they ask you about the gender, we can suppose a cross between Xx and XY being lower x the recessive allele (color-blind vision).
When you draw the Punnett square, you'll found the probabilities are XX, XY, Xx, and xY.
So, you have a 50% chance of having a boy and 25% chance of having a color-blind boy.
The answer should be D because if thats one of your answers on your tests and you missed it, then i would recemend studing. D is the answer because if organisms die, then new ones grow.
According to the Outside-in Model, most of Earth's water arrived after the Earth Formed, from meteorites or comets. This water would have mixed with the material in Earth's upper layers and also come to the surface through volcanic action. More supporting evidence comes from NASA's DAWN space craft launched in 2007, which found evidence of water on ceres and vesta, the two largest objects in the main asteroid belt located between Mars and Jupiter.
Answer: Darwin believed that the desires of animals have nothing to do with how they evolve, and that changes in an organism during its life do not affect the evolution of the species. He said that organisms, even of the same species, are all different and that those which happen to have variations that help them to survive in their environments survive and have more offspring.
