Can I have help please with this 3 questions. I need help with the 3 questions please I want just the answer. 1)You engineer a chromosomally XY mouse in which the SRY gene is inactivated. What do you expect to observe in this mouse? A)The mouse will develop male anatomic features. B)The mouse will develop female anatomic features. C)The mouse’s Y chromosome will convert into an X chromosome. D)The mouse’s X chromosome will convert into a Y chromosome. E)The mouse will exhibit an additional X chromosome (making it XXY).   
2)In which of the following cases will a Barr body be seen? A)only XX B)XY C)XO only D)XXY E)both XX and XXY

Explanation / Answer

The mouse will develop female anatomic features.

Explanation: SRY stands for the sex determining region on the Y chromosome. As name suggests this region help in determining the male sex. The SRY encode the TDF (Testis determining factor) which acts as a transcription factor that can upregulate the SOX9. The SOX9 expression causes the development of primary sex cords which later turn it into a testis. The SRY gene effects normally take place 6–8 weeks after foetus formation and inhibits the female anatomical structural growth in males. It also works towards developing the dominant male characteristics.
