An organism's somatic cells have 6 chromosomes within the nucleus. How many chromosomes are present in that organism's germ cells? 03 Oo O 12 O we don't have any way of knowing
Sex chromosomes have evolved because genes are not enough to determine sex they prevent crossing over and thus promote sex characteristics to only appear in one sex each sex needs to have certain characteristics it is the only way to determine sex
select the true statements regarding the roles of sex chromosomes in human development. Select the true statements regarding the roles of sex chromosomes in human development. The X chromosome does not contain functional genes. An individual missing the SRY region of the Y chromosome will be phenotypically female. XXX females develop normally except for some slight physical abnormalities. XO females are viable, whereas YO males are inviable. Female cells typically contain two active X chromosomes which are both actively transcribed.
