Polygenic inheritance. The characteristics of a person aren't controlled completely by a single gene, but rather several genes that generally only make a small contribution to how the child turns out in the outcome. At one point there was a study that showed over 400 genes were linked to height, so imagine any other characteristics of a person. Environmental effects also serve a large purpose in how a child is to turn out. These children may all be growing up in the same environment, however that's not to say they all grow up the same. They could all be treated the same way and react differently to it, this counts both for physical and mental traits. All human's features such as eye colors, hair color and height are determined by several different genes. As an example, there are around 2 major eye color genes, however there are also around 14 different genes that actually contribute in determining a person's exact eye color. Some are bound to look the same, as they have the same parents, however, just because they have the same parents doesn't mean they all will look exactly alike.
The answer is the third one
The hydrolysis of atp and preparation for reattachment to the thin filament by the myosin head called the recovery stroke.
<h3>What is myosin ? </h3>
Myosins are a class of motor proteins well recognized for their functions in the contraction of muscles and a variety of other eukaryotic motility processes. They are ATP-dependent and in charge of motility based on actin. By Wilhelm Kühne, the first myosin was identified in 1864.
<h3>When the myosin pulls the actin what is happening?</h3>
The actin is drawn along by the myosin head as it advances in the direction of the M line. The filaments migrate nearer the M line by around 10 nm as the actin is tugged. The power stroke is the name given to this motion because it is where force is generated.
