Answer:

the father may be BB++ BB +- BO ++ or BO +-

Explanation:

The blood type is a monogenic inherited trait that has three different alleles: A and B alleles are dominant, while the O allele is recessive. Each parent donates one ABO allele to their offspring. On the other hand, the Rh factor single gene inherited trait that has two alleles: the Rh-negative (-) factor is recessive to the Rh positive (+). Each parent donates one Rh factor allele to their offspring. In this case, the mother has the genotype OO -- (recessive for both genes), while Pablo has a phenotype of B+ and a genotype BO+- (i.e., Pablo is heterozygous for both genes). In consequence, the father may have the following genotypes: BB++ BB +- BO ++ or BO +-, from these combinations you could get a son with the genotype BO+- .

telo118 [61]

Answer:

<em>The correct option is d) distal humerus fracture</em>

Explanation:

The humerus is one of the three bones which join to make up the elbow joint. A break in the lower end part of the upper elbow results in distal humerus fracture. Such types of events are caused due to high energy collisions such as during an accident. The distal humerus fracture can be treated through a surgery. During the surgery, the normal motion of the humerus is tried to be restored.

A population that is decreasing in size will have an age-structure histogram shaped like a(n): 1) inverted pyramid, with a narro

lawyer [7]

The correct answer is - 1) inverted pyramid, with a narrow base representing a small number of young individuals.

The populations that are decreasing are usually population in countries that are highly developed. The conditions for living are excellent, the medical care on high level, life expectancy very high, but the birth rates very low.

In this type of conditions, there's smaller and smaller number of young individuals, with the middle aged population being much bigger, and the older population being constantly on the rise. This will give the age-structure histogram a reverse shape than what it is supposed to have, it will be similar in appearance like a inverted pyramid, meaning that the population is aging and that it will be constantly on a decline in the future.
