Chromosomes

[em123]

Why do chromosomes carry multiple genes in a precise order?

[JackBean]

why not? I don't get your question.It's one piece of DNA carrying several genes, so why should they be randomized?

50% similarity between father and child is sufficient, remember child obtained the genetic material from both father and mother.

[JackBean]

shouldn't you compare Xs only?

[magicsiew]

Is the XX and XY just indication on male and female only, or it really indicate the gene on X and Y?

XY and XX both contains genetic information for the organism and as well indicate whether it is M or F. Just so you know, the X chromosome is mainly the boss, the genes from the Y aren't used that much, so in reality its very BIG X and very very very very small Y.
