Answer:

The sperm and egg have 1/2 the amount because when the sperm fertilizes the egg, it equals out to the regular amount of chromosomes. That is why we have half chromosomes from our dad and half chromosomes from our mom, equaling out to normal amount of chromosomes.

Your first cousin died of tay-sachs disease (autosomal recessive, incidence 0.09%). you are not affected, nor is anyone else in
AlexFokin [52]
<span>25%

   Starting from my First cousin family, I know for sure that the Uncle is is a carrier (Aa) and he must have married a wife who is also a carrier (Aa) and that is how they got an affected son. Thus, this leads to the fact that either both of my grandparents are carriers (Aa x Aa) or only one of them is a carrier (Aa x AA). As a result, the chances that my mom (who is related to the uncle who has a defected child) is a carrier is either (2/3 or 1/2) depending if my grandparents genotype, respectively. Thus, if my mom chances of being a carrier is 1/2 then my chance of being a carrier is 1/4. (given that my dad is not a carrier b/c CF is a rare disease) However, if my mom chance of being a carrier is 2/3 then my chance of being a carrier is (2/3)x(1/2)=(1/3) As a result, I could either be 1/4 or 1/3. But since the answer only provide the choice of 1/4 and not 1/3. This leave 25% is the correct answer.</span>

Elenna [48]
The correct answers are no movement; extensive movement.
You cannot move the joints near your skull - at least now willingly - only a doctor can remove parts of your skull if you are undergoing a brain surgery. Otherwise, there is no movement at all there. However, when it comes to your shoulders, for example, you can move them at will in whichever way you want to.

Scrat [10]
Because everything scientists do or see is put out where the whole world can see. But if they don’t do it accurately then they get proved wrong or even lose their job. And the more accurate an answer is the more opportunity they have to venture and see more Han what they already know.
