Do ionic bonds give electrons?
Korolek [52]

Answer:

In ionic bonds, there is a transfer of electrons from one atom to another. Because of the transfer of electrons, the atoms that gain electrons become negatively charged, while the atoms that lose electrons will be positively charged. [1] If the atom has an additional electron, then the atom becomes a negative ion, known as anion. Meanwhile, if the atom loses electrons, then the atom becomes a positive ion or cation. [2] Because of the difference in charge between ions (positive ions and negative ions), the positive and negative ions will attract each other by electrostatic forces. This event is the basis of ionic bonding.

If a mother has a blood type AB+- and her father has a blood type B- and she marries a man with O- blood type. What is the perce
Marina CMI [18]
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 -.
