Abnormal testes and intersex appearance, frequent X chromosome aneuploidies and deviation from a 1:1 sex ratio were observed.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Experimental cages started with a mixture of flies at three different ratios (1:9, 5:5, 9:1) from populations having heterosomal and autosomal sex–determining mechanisms were cytogenetically examined over six generations at two different temperatures (25 °C and 35 °C).
📊
Key Findings & Data:In general, there was an increase in the frequency of XX males in all competitive population cages.
💡
Conclusion & Impact:Abnormal testes and intersex appearance, frequent X chromosome aneuploidies and deviation from a 1:1 sex ratio were observed.
🔬Design:Lab & Field Experiment
📍Scope:Comprehensive Sample

Abstract

Experimental cages started with a mixture of flies at three different ratios (1:9, 5:5, 9:1) from populations having heterosomal and autosomal sex–determining mechanisms were cytogenetically examined over six generations at two different temperatures (25 °C and 35 °C). In general, there was an increase in the frequency of XX males in all competitive population cages. Abnormal testes and intersex appearance, frequent X chromosome aneuploidies and deviation from a 1:1 sex ratio were observed.

Özet

Otozomal ve heterozomal eşey belirleme mekanizmalarına sahip populasyonlardan, üç farklı oranda (1:9, 5:5, 9:1) sineklerin karışımı ile başlatılan iki farklı ısıdaki (25 °C ve 35 °C) deneysel kafesler, altı generasyon boyunca sitogenetik olarak araştırıldı. Genel olarak bütün populasyon kafeslerinde XX erkek frekansında bir artış vardı. Anormal testisler, interseksüel görünüş, sık X kromosomu aneuploidisi ve 1:1 eşey oranından sapmalar gözlendi.
