In addition to carrying genes, which determine s*x and s*xual characteristics, the s*x chromosomes also carry genes, which determine other traits. Such traits or characters are referred to as s*x-linked or X-linked characters because they are usually found on X Chromosomes (with very few being located on the Y Chromosomes). The human X Chromosomes contain morf than 60 of such genes, most of which are recessive, giving rise to traits like haemophilia, colour blindness, abscence of central incisors.
s*x linked traits are located on the X-chromosome...
Examples of s*x-linked trait are homophilia,baldness and colour blindness..
D is correct ✨
NO NEED TO STRESS YOURSELF AT ALL, just go to MODERN BIOLOGY PAGE 563 subtopic s*x-linked characters and confirm why D is correct.
pls correct this
s*x link genes are located on the X and Y chromosomes
but most s*x linked genes are located on the X
that's why males are susceptible to X linked diseases.
the questions say: s*x linked genes located on
not most s*x linked genes located on
The correct answer is B. X- and Y-chromosomes. Let me explain clearly.
Reasoning:
s*x-linked genes are genes that are located on the s*x chromosomes, which determine the s*x of an individual.
In humans (and most mammals):
Females: XX
Males: XY
Genes on the X chromosome are called X-linked genes. For example: color blindness and hemophilia.
Genes on the Y chromosome are called Y-linked genes. These are much fewer and usually determine male-specific traits, like male fertility.
So, s*x-linked genes are found on both X and Y chromosomes, not on autosomes (homologous chromosomes that are not s*x chromosomes).
Answer: B. X- and Y-chromosomes
s*x linked genes are located on the X chromosome and such gene are inherited along with such X chromosome.
