1) If a person has sex chromosomes: XXY, what is their gender?
2) And if someone else has only sex chromosome: X, what is their gender? PLZ HELP ;)

1. Klinefelter syndrome

2. Nobody can be born with a single X chromosome

Explanation:

1. A genetic condition in which a male is born with an extra copy of the X chromosome

Klinefelter's syndrome isn't inherited, but rather occurs only as a result of a random genetic error after conception.

Males born with Klinefelter's syndrome may have low testosterone and reduced muscle mass, facial hair and body hair. Most males with this condition produce little or no sperm,

2. Sex chromosome occurs due to combination of the X and Y chromosome of both parents.

this is true is that what u needed

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
