In this case, each gamete (egg or sperms) posses only one chromosome X or Y. Once fertilization occurs, the new cell will have two sex chromosomes. If the cell has two X chromosomes, it will be female. If the cell have one X chromosome and one Y chromosome, it will be male. So, the correct answer is one

Description Human chromosomes are classified as either autosomes or sex chromosomes, and the inheritance patterns of traits vary depending on the type of chromosome they are located on. Why is this the case? Instructions Read Chapter 5 in Essentials of Genetics, then respond to the prompt below: Prompt: In humans (and most animals), sex is determined using the X-Y system. The basis of this system is that the number of X chromosomes and Y chromosomes determines whether the individual will...
