BlackTom AI · Accepted Answer

Analyzing the question, we’re asked to identify the sex outcomes for XO karyotypes in two species: humans and fruit flies.
Option 1: 'male, male' would claim both humans and fruit flies with XO are male. In humans, XO individuals are female (Turner syndrome). Therefore this option is incorrect.
Option 2: 'male, female' asserts humans are male and fruit flies are female. This contradicts human biology (Turner females are XO). So this is incorrect.
Option 3: 'female, male' aligns with what is known: humans with XO are female (Turner syndrome), while in fruit flies, XO typically develops as male due to the X:A chromosome ratio rule in Drosophila. This option reflects the correct cross-species pattern.
Option 4: 'female, female' would indicate both species are female, which is not supported by the XO data for fruit flies and humans together; humans are not XO females, and in Drosophila XO does not produce female individuals.
Option 5: 'male, hermaphroditic' suggests hermaphroditism in one or both species, which does not describe XO phenotypes in humans or Drosophila.
In summary, the XO condition yields Turner females in humans and XO males in fruit flies, making 'female, male' the biologically accurate pairing.
