Spontaneous rotational inversion in Phycomyces.
The filamentary fungus Phycomyces blakesleeanus undergoes a series of remarkable transitions during aerial growth. During what is known as the stage IV growth phase, the fungus extends while rotating in a counterclockwise manner when viewed from above (stage IVa) and then, while continuing to grow, spontaneously reverses to a clockwise rotation (stage IVb). This phase lasts for 24-48 h and is s...
متن کاملHeterozygote Detection
saemia in a British hospital, with emphasis on heterozygote detection. Results are reported of a screening programme for galactosaemia covering a period of 2A years and 6415 births. The gene frequency for galactosaemia estimated from the data of the screening programme was 0-002. This conflicted with the known livebirth incidence of at least 1: 50,000 during this same period. 2 of the 4 galacto...
متن کاملHeterozygote Advantage for Fecundity
Heterozygote advantage, or overdominance, remains a popular and persuasive explanation for the maintenance of genetic variation in natural populations in the face of selection. However, despite being first proposed more than 80 years ago, there remain few examples that fit the criteria for heterozygote advantage, all of which are associated with disease resistance and are maintained only in the...
متن کاملHomocystinuria: Heterozygote Detection
cytes as a readily available source of this enzyme, its activity has been compared in 48 control subjects, seven homozygotes affected with homocystinuria, and 17 obligate heterozygotes. PHA-induced enzyme levels were highest in controls (mean ±SEM, 666.9±170.2 pmol cystathionine formed/mg protein per 4 h), intermediate in heterozygotes (114.4±27.3), and absent to severely deficient in homozygot...
متن کاملHeterozygote Hemoglobin J Iran in Combination with Hemoglobin H Disease
This is a report concerning a concurrent case of hemoglobin J Iran (Hb J Iran) and Hemoglobin H (Hb H) disease in an Iranian woman. The patient was coincidentally found during the course of routine pre-marital genetic counselling for her son. The diagnosis of heterozygote Hb J Iran for her son, ultimately led to the diagnosis of concurrent Hb J Iran and Hb H disease. The hematological examinati...
