Answer:
Contract
Explanation:
The main proteins involved in muscle contraction are called actin and myosin.
According to Mendel's Law of segregation, one copy of a gene is passed randomly from each parent to their offspring. This is why gametes have half the usual number of chromosomes. The Law of independent assortment states that different genes are not connected. In other words, the gene for eye color is not influenced by, nor does it influence, the gene for hair color. This allows gametes to form with a random mixture of traits. The cell division that creates gametes according to these principles is known as meiosis.
