NeX [460]

The father of this offspring should be male 3. It is the only individual that exhibits certain molecular genetic markers present in the offspring but absents in the mother.

<h3>Genetic markers</h3>

A molecular genetic marker is a fragment of DNA that can be used to trace the inheritance pattern from parents to offspring.

In this case, parents and offspring exhibit three molecular markers which are shared among them.

There are certain genetic markers that are present in the offspring but they are absent in one of the parents, and therefore they can be used to trace the inheritance pattern.

The area of the muscle fiber where the actin and myosin myofilaments overlap is
Varvara68 [4.7K]

Answer:

Sarcomere

Explanation:

The muscle fiber / myofibrils consist of 2 types of filaments - actin and myosin. The myosin filaments are thick filament whereas the actin filaments are the thin filament.

In addition to this, the muscles have A-band and I-bands. These bands give the muscles alternate light and dark colour band structure. In the A-band, myosin filaments are present, whereas in the I - band the actin filaments are found.

In I-band 2 Z-lines are located.  The area between the Z-lines is called sarcomere. In this sarcomere region both actin and myosin filaments present.

When muscles get contracted the length of the sarcomere shorten. The actin and myosin filaments overlap in this area. A cross-bridge form between them, with the help of filamentous protein titin.
