Use the information below to answer the following questions.
Normally the Y chromosome contains the SRY gene,and the X chromosomes lacks the SRY gene.The SRY gene directs the development of adult male characteristics such as a penis and testes,deeper voice,facial hair,and larger muscles.However,during meiosis,chromosomes exchange genetic material with one another through a process called homologous recombination.One outcome of homologous recombination is for an X chromosome to gain the SRY gene (referred to as X(SRY+) ) .Conversely,through the same process,it is possible for the Y chromosome to lose the SRY gene (referred to as Y(SRY-) ) .
-What biological (chromosomal) gender and adult human characteristics would a zygote having an XX genotype have,assuming the recombination event described did not take place?
