Vedclass · Answer

(D) Statement $(i)$ is False. Sickle-cell anaemia is an autosome-linked recessive trait that is controlled by a single pair of alleles,$Hb^A$ and $Hb^S$.Statement $(ii)$ is True. Trisomy is a type of chromosomal disorder where an extra chromosome is present (e.g.,Down's syndrome,$2n+1$).Statement $(iii)$ is False. Turner's syndrome is caused by the absence of one of the $X$ chromosomes,resulting in a $45$ chromosome count $(44 + XO)$.Therefore,the correct sequence is $FTF$.

Choose the correct answer regarding the following statements:
$(i)$ Sickle-cell anaemia is controlled by three pairs of alleles.
$(ii)$ Trisomy is a chromosomal disorder.
$(iii)$ $47$ chromosomes are present in a person having Turner's syndrome.
