The SRY gene is normally located on the human Y chromosome. This gene initiates the development of male characteristics.
Using this information, which of the following statements about the SRY gene is/are correct?
Insertion of the SRY gene into an X chromosome of a female zygote could give it male characteristics.
A sperm cell arising from incorrect division, which has a functional SRY gene, could give rise to a female with a sex chromosome trisomy following fertilisation with a normal ova.
During meiosis, crossing over could result in the formation of ‘X’ sperm with the SRY gene, which could cause male characteristics after fertilisation.
