Question

Give examples of animals where sex determination is not genetically determined

Answer 1

the microscopic animals are not determined of by sex(female or male)

Answer 2

Answer:

Examples of organisms in which sex is not genetically determined are crocodiles, alligators, turtle, tuatara et cetera.

In these organisms, sex is determined by environmental factors.  

For example, in crocodiles, if the egg is incubated at around 30 °C, it leads to the development of female whereas if the egg is incubated at around 34 °C, it results in the development of the male.

Another example may include Bonellia Viridis in which sex is determined by the location of larvae. If larvae make physical contact with a female, it becomes male. If it is located on the bare sea floor, it becomes female.

Hermaphrodites are the organisms in which sex determination system is not present. For example, earthworm and few species of snails.
