(f) Overview of outcomes
A2 becomes established displaying reasonable segregation when you look at the heterogametic sex—characteristics that comprise a proto-y chromosome. The haplotype containing the recessive female-determining allele A3 becomes founded and additionally exhibits reasonable segregation when you look at the heterogametic sex—characteristics that comprise a proto-x chromosome. The populace ultimately ends up with a combination of heterogametic (A3A2 ? XY) males and homogametic (A3A3 ? XX) females with equal segregation of male and female proto-sex chromosomes within the sex that is heterogametic. Keep in mind that an XY sex-determination system evolves for almost any strength that is initial of.e. Prov —and any amount of linkage between a plus B —i.e. Supplied r1 and allele A2 determines development as a lady. The people would wind up at balance with a combination of heterogametic (A3A2 ? ZW) females and homogametic (A3A3 ? ZZ) men with equal segregation of male and chromosomes that are feminine-determining female meiosis. Also, it will be possible for the model that is above create heterogamety within the other intercourse from where drive initially does occur. To do this you need and then replace the dominance connection of alleles during the the locus. If A3 is dominant to A2, then your driving sex goes on to be homozygous (homogametic) for A2 ( maybe not shown).
