Answer:
I agree and disagree with his statement.
Explanation:
We all know that the blood type AB is the universal recipient, so we know that this bloodtype can recieve any kind of blood. AB-type blood doesn't fight off anything because it has all of the antibodies needed. We also know that type O is the universal donor, meaning that this blood can be donated to anyone. This bloodtype doesn't have antibodies, so nothing will go wrong. However, for the other bloodtypes, yes, things have to be matched carefully. Type B blood can't be given type A blood, and so on. Another thing you have to think about is the Rh factor, which is the +/- after blood types. Rh+ bloodtypes can recieve both Rh+ and Rh- bloodtypes, but Rh- bloodtypes can only recieve Rh- bloodtypes. There are also graphic tables that will help answer this question if you're a visual learner!
I hope this helps, sorry it was a bit late!
Answer:
A. Dominant alleles often encode functional products, whereas recessive alleles often do not encode functional products
Explanation:
One gene can have it's variant forms called allele but in one individual only two allele form of a gene can be present. These two allele form can be the same(homozygous) or different(heterozygous). A dominant allele often encode a function protein of product while recessive allele often code for non- functional product.
Therefore when the dominant allele is present in the chromosome then function products are formed which can be seen in the phenotype and even a single dominant allele produce the functional product like in heterozygous condition so phenotype in heterozygous and homozygous dominant condition appears same. So the correct answer is A.
