Factors that control what sex an individual becomes
structure consisting of DNA and associated proteins that carries and transmits genetic information
the condition of possessing both male and female reproductive structures
having both male and female reproductive parts

XX-XO sex determination
system in grasshoppers where females have two X chromosomes and males posses a single X chromosome
chromosome that is the same in males and females, nonsex chromosomes
the sex that produces gametes that are all alike with regard to sex chromosomes
XX-XY sex determination
system where females have two X chromosomes and males have a single X chromosome and a smaller Y chromosome
small region of the X and Y chromosomes that contains homologous chromosomes
ZZ-ZW sex determination
system in birds, amphibians and fish where females are heterogametic and males are homogametic
genic sex determination
sex determination in which the sexual phenotype is specified by genes at one or more loci, but there are no obvious differences in the chromosomes of males and females
A reproductive pattern in which an individual reverses its sex during its lifetime.
human condition in which cells contain a single X chromosome and no Y chromosome
human condition in which cells contain one or more Y chromosomes along with multiple X chromosomes
human condition in which cells contain three X chromosomes
characteristics determined by a gene or genes on sex chromosomes
possession of a single allele at a locus
failure of homologous chromosomes or sister chromatids to separate in meiosis or mitosis
the sex that produces two types of gametes with respect to sex chromosomes
SRY gene (sex-determining region Y)
equalization in males and females of the amount of protein produced by X-linked genes
