Hi!
So there is a need for scientific names, and I'll tell you why.
Scientists and researchers need to have a "universal language", so they can communicate with others around the world. They use scientific names that normally have Latin origins.
The reason we use common names is so people <em>don't </em>get confused. Normal people won't go around saying they need to walk their canis lupus familiaris. They'd say they need to walk their dog.
Hope this helps ya out fam!

Gneiss typically has a banded, foliated or platy texture.
Carbohydrates; long term use is lipids.

Answer:
Mrs. Ritter, whose blood type is B (Bi) is right in claiming that Ian - blood type A (Ai)- is the father of her baby, with blood type O (ii). Ex-boyfriend AB (AB) cannot be the father.
Explanation:
The blood type, according to the ABO system, is determined by the presence or absence of surface antigens A and B. In addition, genotypes can be co-dominant, in the case of A, B and AB, heterozygous (Ai or Bi) and recessive, in the case of group O (ii)
- <em>
</em><u><em>Type A</em></u><em> contains the antigen A and its genotype can be AA or Ai.
</em>
- <u><em>Type B</em></u><em> contains the antigen B, whose genotype can be BB or Bi.
</em>
- <u><em>Type AB</em></u><em> contains both antigens and a single genotype expression AB.
</em>
- <u><em>Type O</em></u><em> blood lacks surface antigens, its genotypic expression being ii.</em>
According to this, to check if Mrs Ritter's baby is Ian's child, a crossing can be done:
♂ Ai
♀ Bi
Alleles A i
B AB Bi
i Ai ii
<u>Ian and Mrs Ritter have a 25% chance of having a child with blood type O (ii), so the baby may be Ian's child</u>.
To find out why the ex-boyfriend can't be the father
♂ AB
♀ Bi
Alleles A B
B AB BB
i Ai Bi
It is not possible that Mrs. Ritter's ex-boyfriend is the father of the baby, as the possible offspring in the crossover are A, B or AB.
