The correct answer is cork because that is when a scientist first discovered it in greece if i remember right<span />
Answer:
A is correct.
Explanation: At the end of meiosis II there are 3 polar bodies and one octet that are all haploid.
If the mother is a carrier and the father is normal, the outcomes for potential children would be:
XH Xh
XH XHXH XHXh
Y XHY XhY
So let’s break these down
XHXH = will be a daughter (XX) with normal blood (HH)
XHXh = will be a daughter (XX) who is a carrier for hemophilia (Hh)
XHY = will be a son (XY) with normal blood (H)
XhY = will be a son (XY) with hemophilia (h)
Because this disease is inherited on the X chromosome, male offspring tend to either have it or not. They can’t be carriers because they only have one X chromosome. So the chances of having a son with hemophilia will be 50% cause the boys have a 50% chance of inheriting hemophilia.
On the other hand, daughters will either have normal blood or be carriers in this situation. So to answer the question, the chance a daughter of this couple would have of inheriting hemophilia is 0%. This only changes if their father has hemophilia. Then they will either be a carrier or will have hemophilia.
Answer:
Option (B).
Explanation:
Mixture may be defined as the solution obtained by mixing of two or more substances together. Two different types of mixture are homogeneous mixture and heterogeneous mixture.
Homogeneous mixture may be defined as the mixture that has uniform composition throughout the mixture and cannot be separated easily by physical shaking process. Heterogeneous mixture are the mixtures that has different composition throughout the mixture and can be separated by simple shaking.
Thus, the correct answer is option (B).
A). The increase in genetic variation of a population
