Intended Audience This lesson is intended for an introductory biology course for majors, but could be modified for a non-majors biology course through the removal of more sophisticated questions , or revised for an upper level genetics course through the expansion of one or more of the Investigations. The 23rd chromosome pair is unique. Female pigeons ZW have just one Z chromosome, and therefore just one allele for each of the genes located there. Egg and sperm join to make a zygote, which develops into a new offspring. Sex Chromosomes Sex chromosomes determine whether an individual is male or female. All females have two X chromosomes with similar genes aligned in a similar fashion. Consequently, multiple strategies have evolved to ensure that heteromorphic sex chromosomes are segregated faithfully.
