Hope this helps
Ok... This is a bit complicated but bear with me. In a female's body Estrogen and Progesterone are two of the major used to maintain the menstruation cycle. Gonadotrophic substances are an entirely different topic with it being the hormones FSH and LH (These hormones are released while an egg is in development in the ovaries).
Without going into even deeper specifics. Estrogen is used by the body signal to ovulate, as well as thicken the uterine walls... Progesterone is used to maintain the uterine walls "after" the egg is fertilized. What the pill is suppose to do is actually force a premature ovulation, which is why there is estrogen. The Progesterone's job as is maintain the uterine wall's endometrium to a low level and helps keep blood loss from a period at a minimum.
If you need clarification please feel free to question.
Answer:
If a whole specie of organisms has to survive, they should must possess the ability to reproduce and adopt to environmental conditions in better way.
For example: If a disaster occurs or a condition of unfavorable weather occurs, the specie will survive even if only few members remain alive. Because those members will reproduce and regrow the community.
The reason is this that reproduction is not important for the survival of one organism, like organism will still survive even if he do not reproduce, but if a whole specie has to survive and continue, reproduction is most important trait.

Explanation:
<em>Hemophilia typically affects more males than females because the disorder is </em><em>X-linked </em><em>and </em><em>recessive</em><em>. </em>
<u>Females have two X chromosomes (XX) while males only have one X and one Y chromosome (XY). The two X chromosomes in females are capable of carrying alleles while the Y chromosome in males is hypothesized not able to carry alleles. </u>
Consequently, the two X chromosomes in females will both need to carry the recessive allele of hemophilia in order for any female to be affected for hemophilia while the males only need their single X chromosome to carry the recessive allele in order to be affected.
In order words, the presence of a single recessive allele is not enough for a female to be affected while it is more than enough for a male to be affected. Hence, more males are affected b hemophilia disorder than females.
