Spermatogonial crossing over in Drosophila melanogaster and Drosophila ananassae.
FRIESEN (1936) induced crossing over in Drosophila males by X rays and found that most of the exchanges were in a preferred region, the complementary crossover classes were very unequal, and the percent recombination varied greatly from individual to individual. According to him, the data 'were sufficient to demonstrate the occurrence of spermatogonial crossing over. WHITTINGHILL (1937) found t...
متن کاملSegregation distortion and crossing over in males of Drosophila ananassae. I. Preliminary genetic analysis.
ANDLER and NOVITSKI (1957) proposed the term “meiotic drive” (or segregation distortion) to describe a condition which leads to unequal segregation of the two alleles present in a heterozygote in consequence of certain aberrant mechanisms during meiosis. SANDLER, HIRAXZUMI and SANDLER (1959) and SANDLER and HIRAIZUMI (1959, 1960) have made a detailed analysis of this segregation distortion phen...
متن کاملElements causing male crossing over in Drosophila melanogaster.
A second chromosome line of Drosophila melanogaster (Symbol: T-007) has previously been shown to be responsible for the induction of male recombination. In the present investigation, the genetic elements responsible for this phenomenon have been partially identified and mapped. A major element (Symbol: Mr, for Male recombination) locates on the second chromosome between the pr (2L-54.4) and c (...
متن کاملMale recombination in Brazilian populations of Drosophila ananassae.
With few exceptions, spontaneous crossing over does not normally occur in male Drosophila. Drosophila ananassae males show considerable amounts of crossing over. In wild males of D. ananassae from Asian (2008) and Brazilian populations (1986 and 2007) variable frequencies of meiotic crossing over, estimated from chiasmata counts, suggested the existence of factors controlling male crossing over...
