Which of the following is NOT TRUE about Y-linked disorders?
Usimov [2.4K]

Answer:

<em>The statement which is not true is C) They can affect males or females</em>

Explanation:

All the chromosomes in a person are known to be autosomal chromosomes except for the sex chromosomes. The sex chromosomes are of two types: Chromosome X and chromosome Y.

Both the sex chromosomes are X in females. Males have one X chromosome and one Y chromosome. The Y chromosome is shorter than the X chromosome. The Y chromosomes occur only in males. Hence, Y- linked disorders will affect only males. These disorders will never occur in females.

Which is not a cost for organisms that sexually reproduce?
Alekssandra [29.7K]

Answer:

Identical shape and structure.

Explanation:

Those organisms that reproduce sexually have high variations and differences between the parent and its offspring. They are not identical to each other because the offspring gains half characteristics from male parent and half from the female parent making it different from its parent. Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.
