Vedclass · Answer

(D) Environmental determination of sex refers to the process where environmental factors like temperature or chemical signals influence the sex of an organism.In $Bonellia$ (a marine worm),the sex of the larva is determined by its environment. If a larva settles alone,it develops into a large $(2.5 \ cm)$ female. If it lands on or near an existing female,chemical substances secreted by the female cause the larva to develop into a tiny $(1.3 \ cm)$ male.In many reptiles like turtles and alligators,the incubation temperature of the eggs determines the sex of the offspring. Generally,a temperature below $28^{\circ}C$ produces more males,a temperature above $33^{\circ}C$ produces more females,and a temperature between $28^{\circ}C$ and $33^{\circ}C$ produces both males and females in equal proportions.Therefore,all the given examples exhibit environmental sex determination.
