Genus
for example
scientific name for tiger : Panthera Tigris
Panthera is the Genus name
Tigris is the Species name
hope this helps
Evolution is the change in an animal over time. Evolution causes this one animal to branch out into many different species of animals.
How evolution starts- There is a mutation in the genes of one animal. If the mutation helps the animal, than the animal breeds and passes on this mutation. This is natural selection. Natural selection is the starting point of evolution because all of the helpful mutations get passed down to change the species over time for the animals' benefit.

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!

If p = frequency of A and q = frequency of a, then assuming H-W equilibrium we have
p + q = 1 ⇒ q = 1 - p = 1 - 0.55 = 0.45
Then the expected frequency of the heterozygous genotype Aa is 2pq = 2 • 0.55 • 0.45 = 0.495.
Answer:
The most appropriate answer would be option 2.
In humans, the color of the eyes was thought as a simple Mendelian trait however, it has been found that the color of the eye follows polygenic inheritance, that is, it is determined by multiple genes.
A set of 15 genes is responsible for the color of the eyes. Two genes out of these 15 are OCA2 and HERC2 which are present on chromosome 15.
Thus we can conclude that eye colour is polygenic trait which does not follow Mendelian genetics.
