What is the default sex in some species that lack sex chromosomes?
Male
Female
Hermaphrodite
Asexual
The default sex in certain organisms without sex chromosomes is female. This is due to the fact that in many animals, sex is determined by other factors other than the presence or absence of sex chromosomes, such as the number of chromosome sets, the environment, or other genetic factors. Individuals from these animals will naturally develop as females if they lack the genetic or environmental cues to do so. For instance, in honeybees, fertilized eggs become queens or workers, but unfertilized eggs become drones. The temperature at which the eggs are incubated can affect the sex of the young in several fish and reptile species, with cooler temperatures resulting in females and warmer temperatures resulting in males. Hence, option 2 is the correct answer.
