How do most autosomal recessive alleles that lead to lethal diseases persist in human populations?

Biology

enyata [817]4 years ago

<span>Autosomal recessive alleles that lead to lethal diseases persist in human populations because these diseases happen after people have their children. They get inherited from both parents, one from each. The two mutated genes carry a 25 percent chance in having two normal genes in the child, a 25 percent of two recessive genes in an affected child and a 50 percent chance of an unaffected child who also is a carrier.</span>

Answer:

Answer No 1:

The three ways evolution is determined to have occurred are:

A. Molecular similarities

C. Homologous structures

E. Fossil evidence

Explanation:

Since the theory of evolution became popular, scientists have been looking for similarities and differences among organisms so that they can compare which organisms have a more closer ancestor together as compared to other organisms. Scientists look for molecular similarities, such as the similarities in the proteins and other molecules to depict relations among organisms. Homologous structures is a common term in evolutionary studies in which organisms which are more closely related are known to be more similar. Fossil evidences also help a lot in evolutionary studies.'

Answer No 2:

The correct option is C. the most reproductively successful

Explanation:

Natural selection tends to favour the fittest organism.  In evolution, 'the fittest; means the organism which have the ability to survive in an environment and to pass on its characteristics to its offspring. The organism which is more reproductively successful is considered to be more successful.

Viruses evolve rapidly in part because of the error-prone nature of their replication enzymes, but not all viruses evolve at the
Ierofanga [76]

Answer:

retroviruses

segmented viruses

Explanation:

A retrovirus is a type of RNA virus that inserts a copy of its genome into the DNA of a host cell that it invades resulting in changing the original genome of that cell. There are about three examples of retroviruses, they are

* HIV

* Human T-lymphotropic virus type 1 (HTLV-1)

* Human T-lymphotropic virus type 2 (HTLV-II)

It should be understood that there is a difference between virus and retrovirus. This is that a retrovirus inserts its genome into the host's genome unlike the virus.

Segmented viruses are viruses that package all of their genome segments into a single particle.

In this case, these viruses have high rate rate of genetic mutation and adaptation.

The ______ is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the _______ joint.
Setler [38]

The acetabulum is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the coxal joint.

The acetabulum is made up of the three bones that make up the coxal bone (hip bone).

The ischium, which offers the lower and side limits to the acetabulum, makes up somewhat more than two-fifths of the structure.

Less than two-fifths of the acetabulum's structure is provided by the ilium, which also serves as the top limit of the joint.

The pubis, which is close to the midline, forms the remainder.

The acetabulofemoral joint (art. coxae), also known as the coxal joint, is the joint between the head of the femur and the acetabulum of the pelvis.

Its main job is to support the weight of the body in both static (such as while standing) and dynamic (such as when walking or running) postures.
