Natural selection leads to increases in the mean fitness of populations and so will reduce the frequency of disease-associated alleles, but other evolutionary processes, such as mutation and gene flow, may introduce or increase the frequency of these deleterious alleles.
Intramembranous Ossification is the formation of bone from within fibrous membranes.
The other method of bone formation, Endochondral Ossification, is the formation of bone from preexisting hyaline cartilage models.
Answer:
16 genetically different offspring
Explanation:
This is the case as each parent has the ability to produce 4 uniquely different gametes through independent assortment. With such a scenario where each parent can product 4 uniquely different gametes multiplied by 4 parents, you have 16 offspring. So there's the possibility of producing 16 offspring that are unique.

DNA is a long fiber construct that looks like a strand of hair, and a chromosome is a product of DNA.
''So, what do you understand by DNA anyway? DNA can be described as a long fiber that resembles a hair under a powerful microscope. The only difference is that they are much thinner and longer. The whole structure is made of two strands that are intertwined together. When cells get ready to divide, proteins attach themselves to the DNA and leads to the creation of a chromosome.
A chromosome is simply the product of the DNA and the proteins that are attached to it. There are 23 pairs of the chromosomes in every human being. One set is inherited from the father, and one set is inherited from the mother. A DNA is a sort of a bio molecule. The entire DNA in cells can be found in individual pieces that are called chromosomes.
