Vedclass · Answer

(C) In bacteria,sex determination is not based on sex chromosomes (allosomes) but is controlled by specific genetic elements known as the $F$-plasmid (fertility factor) or sex factor.Bacteria do not exhibit sex determination based on environmental factors; rather,it is a genetically regulated process involving the transfer of genetic material through conjugation.Therefore,the Assertion is correct as it refers to non-allosomic genic determination,but the Reason is incorrect because sex in prokaryotes is not determined by environmental factors.

$A$: Non-allosomic genic determination of sex is found in bacteria.
$R$: Sex is dependent on some environmental factors in prokaryotes.
