Analysis of sterility observed in Agrifound White A indicated that it is probably of GMS ( Genetic male
sterility) type and the male fertility is dominant over male sterility and is a new source of male sterility in onion.
Robert Leonard stated, "Fifty percent of men in America will be affected by genetic male
Disruption of sexual differentiation in genetic male
common carp (Cyprinus carpio) exposed to an alkylphenol during different life stages.
Whatever the final answer, genetic male
pattern baldness appears in 95 % of all cases (American Medical Association Medical Library, 1999) and there doesn't seem to be a choice in the matter.
The appearance of a genetic male
showing female or intersex gonads, or vice versa, would demonstrate an effect of the treatments.
rugosa, exogenous estrogen induces ovarian formation in genetic males
, and the estrogen-sensitive period is clearly defined during days 20-22 after fertilization; b) eggs from each spawn are numerous (about 700-2,000 eggs); c) the method of exposure is simple because tadpoles are aquatic; and d) genetically all-male tadpoles are easily produced.
This means that the bacteria convert genetic males
into females or kill male embryos that are then eaten by their sisters or make females lay unfertilised eggs that all become females.
produce a pigment that makes them orange, while genetic females are white.
Evidence that estrogens are involved during sexual differentiation include the induction of ovarian development in genetic males
by the exogenous application of natural estrogens such as estradiol.
Estrogens can induce a sex reversal in genetic males
, where either an ovotestis is produced or complete and permanent feminization occurs (Lofts 1974).
The bacteria spread via eggs of an infected mother and play havoc with reproduction, causing such oddities as virgin births in wasps, mating incompatibilities in mosquitoes, and genetic males
with female bodies in wood lice (SN: 11/16/96, p.
In ovo exposure of fish to the synthetic estrogen ethinyl estradiol can cause genetic males
to sexually differentiate as phenotypic females (Papoulias et al.
