Answer:
1. Meiosis 1.
2. Meiosis 2.
3. End.
4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.
B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.
C. Meiosis.

Skeletal and Muscular Systems
Answer:
The answer is Endothermic!
Answer:
Will never go to fixation.
Explanation:
Mutation is the sudden, heritable change in the genetic sequence of the organisms. The mutation might cause the particular disease in the organisms.
The gene fitness leads to the increase in the gene frequency in the upcoming generations. The gene will fix in the population when their i no selection and no mutation. Since, the information given in the question states that mutation is acting, so the A allele will never fix in the population.
Thus, the answer is option (c).
