Answer:

  1. Every sperm cell has a Y chromosome. The sex of the child could either be a boy or a girl since there is always a 50% chance that the offspring could be either of the sexes.
  2. Typically, the sperm type that is able to fertilize an egg is the fertile sperm. Fertile sperm can also be called as eusperm or eupyrene sperm.
  3. I cannot see the punnett square, but there is always a 50% probability that the male and female parents could produce a male or female offspring.
  4. The X sex chromosome is the one present in both sexes.
  5.  The Y chromosome determines a person’s sex since only males have such chromosome. If the offspring lacks this chromosome, then the child will be a female. If the offspring has such chromosome, then the child will be a male.
  6. One factor that can affect the expression of an individual’s sex is the deficiency or addition of a sex chromosome. These can be observed in people with Turner’s syndrome or Jacob’s syndrome.

Explanation:

Determining the sex of an offspring is difficult to know. Basically healthy egg and sperm will promulgate to a 50% chance of either of the sexes, theoretically. Unless if there are some problems either of the parent cell, that could cause a disturbance of the offspring. Y chromosome determines the sex of an offspring. The gene SRY in Y chromosome is the responsible for determining a human sex.

Problems cause confusion of sex, such as:

  • gene XXY (Klinefelter syndrome) a male is born with an extra X chromosome.
  • Turner’s syndrome is a genetic disorder (women) that one of X chromosome is absent.
  • Jacob’s syndrome is a genetic condition in which a male has an extra Y chromosome.

Reminder, sex and sexuality are not the same. In short term, sex is male or female (from gene offspring or chromosomal gene). While sexuality is a person's orientation in the society.
