  • Sex chromosome morphology of eight Lepidoptera species was studied, exploiting predominantly the pachytene stage when chromosomes display a remarkable chromomere pattern. Six species had a WZ/ZZ sex chromosome system, one species a W1W2Z/ZZ system and one species was of the Z/ZZ type. Much like XY chromosomes in groups with male heterogamety, the lepidopteran sex chromosomes showed various degrees of structural differentiation. Differences between Z and W chromomere patterns ranged from… CONTINUE READING
