Susan, a mother with Type B blood, has a child with Type B blood. She claims that Craig, who has
laiz [17]

Answer:

A child with type B blood can have a mother with type B blood and a father with type O blood so the judge grants her request and decides due to Susan is right and Craig must pay child support (option b).

Explanation:

Susan is right in this case because her <u>son with type B blood may have a mother with type B blood and a father with type O blood</u>.

Blood types, according to the ABO system, depend on the existence of surface antigens A or B —Types A, B and AB— or their absence in the erythrocyte membrane.

In the inheritance of blood groups A and B are co-dominant, while the absence of antigens —type O— is a recessive trait.

Assuming that Susan has a genotype B/B and that Craig has a genotype O/O:

<em>Alleles      O     O </em>

<em>B            B/O  B/O </em>

<em>B            B/O  B/O</em>

So it is very likely that the child is Craig's son and Susan is right.

Mendel studied pea plants for particular traits.
max2010maxim [7]

Answer:

A scientific law is formed when the results of an experiment generate the same results every time a particular experiment is performed. A scientific law is made when something has been thoroughly tested again and again through experimentation. Unlike the theory, a scientific law is not subjected to change with time. A scientific law is accepted universally and other hypothesis can be generated based on the authenticity of the law.

ololo11 [35]

Answer:

C.The two species do not breed in the same area, so they are reproductively isolated by allopatry.

Explanation:

Allopatry means that these two species are geographically separated during the breeding season, so they are reproductively isolated.

Allopatric speciation is a form of speciation (creation of new species) that occurs as a result of geographic isolation. This means that a part of population becomes physically separated from the initial main population. There is no gene flow between these two populations and as a result the two populations  reach a high level  of genetic divergence. They can no longer interbreed which means they become two different species (speciation).
