Answer:
I.
Explanation:
The woman's father has haemophilia so his genotype must be XhY, so his daughter can only have the following genotype: XHXh. Her husband is not a haemophiliac so his genotype must be XHY. There is a 50% chance that the mother's gamete has the recessive allele for haemophilia. If she has a son that son will have a 50% chance of getting the Xh. This also applies to daughters, but they will get the normal allele XH from their father so the daughter will have a 0% chance of developing haemophilia.

Answer: Fossil records help provide clues to the history of Earth's organisms. They've have given scientists clues needed to determine a present day organism's ancestry by comparing them with fossils. Fossil records also show that life has evolved from simple to complex; for example, fossils deeper into the ground (older ones) are much more simple than the ones at the top (newer ones), again supporting the idea of evolution. Fossils additionally show us how behaviors have evolved, how long individuals lived, and how features evolved over time.
