Q241
According to Dosage compensation in Drosophila
A.
The maternal chromosom are hyperactivated
B.
The Y chromosome is hyperactivated
C.
Both X chromosomes are hypoactivated
D.
Paternal chromosomes are hyperactivated
AnswerAnswer: Option D
Solution
Answer: Option D
Solution:
According to Dosage compensation in Drosophila, Paternal chromosomes are hyperactivated.Dosage compensation in Drosophila increases the transcription of genes on the single X chromosome in males to equal that of both X chromosomes in females.
In Drosophila, the Y chromosome has lost most of its genetic content and is retained in the karyotype only because of its specific genetic function in spermatogenesis.
