Genetics, blood type gene has two alleles, each allele has genotype A, B or O. The A and B are dominant, and O is recessive. So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A, BB is type B, OO is type O, and AB is typeAB.
If both parents have type A blood, then the alleles could be AA or AO, thus the allele A frequency is 75%, allele O frequency is 25% for both parents.
So the chance of alleles OO is 25% × 25% = 6.25%,
alleles AA is 75% × 75% = 56.25%,
alleles AO is 75% × 25% = 18.75%,
alleles OA is 25% × 75% = 18.75%.
Since AA, AO and OA are blood type A, and OO is blood type O, thus their child has 6.25% chance to be blood type O and 93.75% chance to be blood type A.
The +/- is called the rhesus factor, with + being dominant, and - being recessive.
So if both parents are -, the kids are always -, otherwise the kids might be + or -.

Say B is the genotype for example. If her whole family is attached, then she would be Homozygous Dominant. For example, BB.
Answer:
It would be C
Explanation:
If you look at the tree you can see that one of the male's parents had the recessive allele, and one of the siblings has the ressive allele, the means the male could have the trait but isnt showing it.
Answer:
See the answer below
Explanation:
<em>Increasing the concentration of the acid means that the number of ions/particles in the reaction vessel has increased. The higher the number of ions/particles, the higher the frequency of collision of these ions provided that the volume of the reactants remains unchanged. </em>
It is just like comparing a densely populated area with a sparsely populated area. You are more likely to encounter people at a higher frequency in a densely populated area when compared to a sparsely populated area.
Lots of differences, but here's one: Carbohydrates are more rapidly transformed by the body into energy than lipids are. As a result, carbohydrates have a more pronounced impact on insulin levels than lipids do.<span />
