This can be because of their genetics. The siblings may not have inherited their parents looks, but maybe they inherited their grandparents looks, or even their aunts looks. This is all due to genetics. It's sort of the same thing, when two caucasian parents have an african-american child. That would be because somewhere along the family tree someone was african-american.
Anyways, I hope this helps!

Answer:

C) Each child receives only half of each parent’s genes.

Explanation:

In sexual reproduction, the offspring receives half the genetic information from their mother and half from their father. The offspring so formed will have a different combination of genes from the parents. So, the siblings are not identical to their parents.

2. Which of the genotypes listed above would provide the strongest evidence that the alleles for blood type are co-dominant? Ple

Ket [755]

Answer:

Explanation:

Blood group is discovered by famous scientist Karl Landsteiner in the year 1990. Co-dominance is the expression of the two alleles in the heterozygotes. In AB type, the two different alleles are present and they are expressed.

However in ABO type, it is govern by three allele namely A, B and O type. If only the antigen A is present, it is called A blood type. When only B antigen is present it is called B blood type and when both A and B are present, it is called AB blood type. And if neither of the antigen are present, it is called the O blood type.

The allele O is of recessive to both the blood type A and B. So a person with O blood type have two copies of O allele. But however A and B blood type are dominant of O, a person with A blood type may have one of the two genotypes -- AO or AA. Similarly, with blood type B, the genotypes are BO or BB.
