Sagot :
Answer:
- 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.
- 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.
- 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.
- The X sex chromosome is the one present in both sexes.
- 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.
- 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.
