EMBRYOLOGY OF DIPLOID × DIPLOID AND DIPLOID × TETRAPLOID CROSSES IN POINSETTIA

Canadian Journal of Genetics and Cytology, 1969
Hybridization between diploid cultivars of poinsettia results in abundant seed production. However, with the diploid used as the maternal parent in crosses with tetraploids, less than 1% viable seedlings are realized. Cytological observations indicated a 2:3:2 chromosome number ratio of the embryo, endosperm and maternal tissue in diploid crosses with

Diploid parthenogenesis and androgenesis in diploid Solanum

Euphytica, 1972
Diploid parthenogenetic and androgenetic plants were found in certain interspecific hybrid combinations in diploid Solanum. Self progenies of parthenotes of S. verrucosum appeared highly uniform and 100% homozygous for resistance to Race 1.2.3.4 of Phytophthora infestans. They can be of prime importance for breeding if homozygous lines are needed.

Diploid Cell Measles Vaccine

JAMA: The Journal of the American Medical Association, 1986
To the Editor.— Dr Albert Sabin and one of us (J.F.D.)1,2recently reported seroconversion in infants administered measles vaccine of human diploid cells (HDCs) that contained the Ikic (Edmonston-Zagreb) strain and 1% human albumin, or chick embryo fibroblast (CEF) vaccine that contained the Edmonston-Schwartz strain by cutaneous or aerosol routes.

Diploids in Microsporum gypseum

Mycopathologia et Mycologia Applicata, 1974
The paper studies diploids in dermatophyteMicrosporum gypseum. They were isolated as the more rapidly growing sectors from heterokaryons on minimal medium. They are characterized by their wild morphology, conidiation and growth rate, and they are prototrophic. In their genome they contain all the markers present in both mutant components.

Diploidization inEleutherodactylus (Leptodactylidae-amphibia)

Experientia, 1974
El contenido de DNA deE. binotatus (2n=22) es cerca de cuatro veces mayor que el deE. guentheri (2n=22) yE. parvus (2n=22). Ese aumento drastico podria ser resultado de duplicationes intersticiales y/o poliploidia, con translocaciones multiples.

Compensatory evolution in diploid populations

Theoretical Population Biology, 2008
Compensatory mutations are individually deleterious but harmless in appropriate combinations either at more than two sites within a gene or on separate genes. Considering that dominance effects of selection and heterodimer formation of gene products may affect the rate of compensatory evolution, we investigate compensatory neutral mutation models for ...
