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 -.

Condensation of nuclei. They make up clouds
Answer: Hi!
Your answer would be a), eukaryotic cells. We should automatically know that prokaryotic cells are less complex than eukaryotic cells. However, the last two options, Ebola and Virus, are both viruses. Viruses are not considered living and they don't really do anything besides replicate, which they need living cells to do. On the other hand, Eukaryotic cells have organelles, a nucleus, etc. They are definitely classified as living, and complex!
Hope this helps!
