Scientist a set of genetic information for each form as "an allele".
<u>Explanation:</u>
The variant type of a given gene is known as "an allele" which depicts it is one of two or more versions of a recognized mutation on a chromosome at the same location. For a multi-hundred base-pair an allele is multiple sequence variations also for more locations of genome coding for a protein.
Huge amount of genes have a variety of different types, clustered on a chromosome at the same location, or genetic locus. Human beings are taken as diploid species reason behind is, as they have two alleles at each genetic locus, with each parent inheriting one allele.
It may be A but im am not so sure but anyways.
Good Luck
V-shaped valley
As the river erodes downwards the sides of the valley are exposed to freeze-thaw weathering which loosens the rocks (some of which will fall into the river) and steepens the valley sides. The rocks which have fallen into the river help the process of corrasion and this leads to further erosion.
It would be most likely that their children has blood type AB.
