PHENOTYPE

Post by cvic1 » Tue Dec 04, 2007 3:48 am

You discover a new species of animal which bears, superficially, no known relationship to any living animal. All individuals of the species are phenotypically the same, but the species reproduces sexually. How will you be able to determine which sex is which?

Can any help with this question. I don't really understand it myself.

Maleness or femaleness is determined by sex chromosomes.

Thanks, So I would have to check it's chromosomes to determine it's sex. What if it is neither a male or female?

Then it did not come from sexual reproduction which is stipulated in your original post.
