In the concept of biological sex determination, the presence of which alleles indicates a male?
Understand the Problem
The question is asking about the genetic alleles associated with male biological sex determination. It requires knowledge of the AMELX and AMELY genes to determine which option correctly identifies male alleles.
Answer
XY alleles indicate a male.
The presence of XY alleles indicates a male in biological sex determination.
Answer for screen readers
The presence of XY alleles indicates a male in biological sex determination.
More Information
In most mammals, including humans, males are represented by the XY chromosomal configuration, whereas females are represented by the XX configuration. The Y chromosome, although smaller, contains genes crucial for male development, such as the SRY gene, which triggers male sex determination.
Tips
A common mistake is confusing chromosomal alleles where 'XY' indicates male and 'XX' indicates female in humans and other mammals with environmental or genetic variations in other species.
