Inbreeding i believe..... you can have same set of alleles if related
Answer:
The food resources of the finches vary in regard to the island, it is for that reason that we observe differences in the finch beak size
Explanation:
Evolution explains how the survival of the most adaptive organisms to the environment (in this case birds with suitable beaks) makes that they perpetuate their genes in future generations
the color of the water would be CCCCCCCCCCCC (c) BLUE
Answer:
For a woman with type O blood and a man with type B blood, whose mother was of type O blood, the possible offspring will consist of B and O children.
Explanation:
Blood type is an inherited trait and is determined by the presence or absence of antigens A and B on the surface of the erythrocyte:
- <u><em>Blood type A</em></u><em> contains the antigen A and its genotype can be A|A or A|O.
</em>
- <u><em>Blood type B</em></u><em> contains the antigen B, whose genotype may be B|B or B|O.
</em>
- <u><em>Blood type AB</em></u><em> contains both antigens and a single genotype expression A|B.
</em>
- <u><em>Blood type O</em></u><em> lacks surface antigens, with a unique O|O genotype.
</em>
In the above case, the woman has an O blood type, whose genotype is O|O. The male must be heterozygous, since his mother was of blood type O, so his genotype is B|O.
To know the possible descendants of this couple, the crossing of the wolf alleles must be done:
Alleles B O
O B|O O|O
O B|O O|O
From where the probabilities of the offspring are obtained:
- Individuals with blood type B and genotype B|O 50%
- Individuals with blood type O and genotype O|O 50%
Therefore, from this crossing only descendants of individuals with blood type B and O can be obtained.
