Explanation:
Hemophilia is a disorder in which blood doesn't clot normally.
Lets consider Xn as hemophilia gene.
So woman affected with hemophilia will have XnXn gene and man not affected with hemophilia will have XY gene.
When they both undergo crossover, genes in child will be XXn (girl -carrier), XXn (girl -carrier), XnY (boy-affected) and XnY (boy-affected).
Parent Gene:
XnXn (affected woman)
XY (Man not affected)
After crossing over - children gene for first generation:
- XXn (girl-carrier)
- XXn (girl-carrier)
- XnY (boy- affected)
- XnY (boy- affected)
Hemophilia is a X - linked recessive disease which means women are only carrier for this disease untill or unless both the X genes are hemophilia gene and man have more chances to get affected as they have only one X - linked gene.
It means 2 out 4 children are affected.
So, there are 50 percet chances that their first child will have hemophilia.
Answer: Ocean currents can affect the climate of nearby land. Cold ocean currents make nearby land colder and warm ocean currents make nearby land warmer. Places near the ocean experience moderate temperatures year round due to the fact that water has a high specific heat, meaning that it cools and warms slowly. Places further inland have a higher temperature difference between seasons because land has a low specific heat which means that it cools and warms quickly. Ocean currents influence rainfall patterns. Warm, moist air associated with warm ocean currents increase precipitation.

Answer:
Explanation:
The two main types of bone tissue are compact (hard and dense) and cancellous (spongy and flexible) tissue.
An amniotic egg has a clump of nutrients that is used to sustain the embryo during development. This clump of nutrients is called the yolk, and the yolk sac encloses it.
