Question

In a man, sex-linked characters are mainly transmitted through
A. Y- chromosome
B. autosomes
C. X-chromosome
D. X-chromosome, Y-chromosome, and autosomes

Answer 1

Hint:- The X chromosome, being large, mainly carries sort of many truly greater genes than does the Y. Recessive intercourse-connected tendencies, specifically such as hemophilia and purple–inexperienced color blindness, essentially occur a long way fairly greater frequently in guys than in women, very besides showing how recessive intercourse-linked traits, simply consisting of hemophilia and pink–green coloration blindness, essentially occur always form of extra frequently in guys than in ladies in a fairly important way.

Complete Answer:-A human for all intents and functions male simply has intercourse chromosomes, the X and the Y. not like the autosomes (non-intercourse chromosomes), the X and Y don't convey the equal genes and aren't taken into consideration homologous, which for all intents and functions within reason full-size. As opposed to an X and a Y, a surely human virtually lady has X chromosomes, which honestly is quite enormous. these X chromosomes certainly do form a bona fide homologous pair, showing how a real human usually male has two intercourse chromosomes, the X and the Y. in contrast to the autosomes, the X and Y don't, in reality, convey the equal genes and aren't taken into consideration homologous, which is pretty massive. because intercourse chromosomes don't usually essentially come in homologous pairs, the genes they bring display particular, unique styles of inheritance, which more often than not indicates that a typically human essentially male has two intercourse chromosomes, the X and the Y. not like the forty-four autosomes, the X and Y don't carry the identical genes and aren't taken into consideration homologous, or so that they surely concept.
Hence the correct answer is option is C. In a man, sex-linked characters are mainly transmitted through X-chromosome.

Note:- The X chromosome especially is considered one of the intercourse chromosomes, which basically within reason full-size. Egg cells all particularly contain an X chromosome, while sperm cells particularly contain an X or a Y chromosome, or so that they are the main idea.
