Male Heterogametic Condition in Organisms
Male heterogametic condition refers to the condition where the male organism produces two different sex chromosomes, X and Y, whereas the female organism produces identical X chromosomes. This condition is observed in many organisms, including humans, grasshoppers, and Drosophila. However, there are some exceptions where male heterogametic condition is not observed.
Organisms without Male Heterogametic Condition
Birds are the organisms where the male heterogametic condition is not observed. Instead of having separate sex chromosomes, birds have a system called ZW sex determination, where females have two different sex chromosomes, Z and W, and males have two identical Z chromosomes. This is opposite to the XY sex determination system observed in humans and many other organisms.
In birds, the female is heterogametic (ZW), and the male is homogametic (ZZ). Therefore, it is the female bird that determines the sex of the offspring, unlike in humans, where it is the male that determines the sex of the offspring.
Conclusion
In conclusion, male heterogametic condition is not observed in birds. Instead, birds have a ZW sex determination system, where the female is heterogametic and the male is homogametic. This system is opposite to the XY sex determination system observed in humans and many other organisms.
