APAKAH MAKSUD METAFEMALE dalam CORSICA?
Metafemale
Seorang metafemale adalah daya tahan rendah Drosophila fly buah dengan fenotip perempuan di mana nisbah kromosom X untuk set autosomes melebihi 1.0. Sebagai contoh: lalat dengan satu kromosom X dan dua set autosom adalah lelaki normal, lalat dengan dua kromosom X dan dua set autosomes adalah wanita biasa, dan lalat dengan tiga kromosom X dan dua set autosomes adalah metafemale . Ahli genetik Amerika Calvin Bridges, yang menemui keseimbangan genetik sistem penentuan seks di Drosophila pada tahun 1921, menggunakan istilah "superfemale" dan "supermale". Ahli genetik Jerman-Amerika Curt Stern mencadangkan istilah ganti "metafemale" dan "metamale" pada tahun 1959.

Metafemale syndrome (XXX) occurs when an XX gamete combines at fertilization
with an X gameto. Metafemales are female but are often sterile and may have a
reduced mental capacity. • Turner's syndrome (XO) persons lack Barr body.
