IRREGULAR GENETIC TRANSMISSION IN TETRAHYMENA CROSSES [PDF]

open access: yesGenetics, 1963
LLEN (1960) reported briefly an aberration in the breeding behavior of a Astrain (C*) of variety 1 of Tetrahymena pyriformis. Her later studies (ALLEN 1963) established the genetic parameters of the aberration and lead to the conclusion that the total genome of the C* strain is systematically excluded at conjugation.

Humanized Mice and the Rebirth of Malaria Genetic Crosses [PDF]

open access: yesTrends in Parasitology, 2020
The first experimental crosses carried out with the human malaria parasite Plasmodium falciparum played a key role in determining the genetic loci responsible for drug resistance, virulence, invasion, growth rate, and transmission. These crosses relied on splenectomized chimpanzees to complete the liver stage of the parasite's life cycle and the ...

Genetic architecture of atherosclerosis dissected by QTL analyses in three F2 intercrosses of apolipoprotein E-null mice on C57BL6/J, DBA/2J and 129S6/SvEvTac backgrounds.

open access: yesPLoS ONE, 2017
Quantitative trait locus (QTL) analyses of intercross populations between widely used mouse inbred strains provide a powerful approach for uncovering genetic factors that influence susceptibility to atherosclerosis.

THE APPLICATION OF DISCRETE HIDDEN MARKOV MODEL ON CROSSES OF DIPLOID PLANT

open access: yesBarekeng, 2023
The hidden Markov model consists of a pair of an unobserved Markov chain {Xk} and an observation process {Yk}. In this research, the crosses of diploid plant apply the model.

Construction and extension of complicated genetic models for multiple-cross mating designs

open access: yes浙江大学学报. 农业与生命科学版, 2004
According to the principles of general genetic model, and based on multiple-cross mating designs, additive-dominance-epistatic models with GE interaction and seed models including four genetic systems of diploid embryo, triploid endosperm, cytoplasm and ...

Combining ability and heritability estimates of main agronomic characters in rapeseed breeding lines using line × tester analysis [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2012
To estimate the general and specific combining ability (GCA and SCA) effects of plant height, yield components, seed yield and oil content, three testers and six lines of spring type of rapeseed varieties were crossed using line × tester fashion ...

The quantitative genetic basis of sex ratio variation in Nasonia vitripennis : a QTL study [PDF]

open access: yes, 2010
Our understanding of how natural selection should shape sex allocation is perhaps more developed than for any other trait. However, this understanding is not matched by our knowledge of the genetic basis of sex allocation.

A Statistical Variance Components Framework for Mapping Imprinted Quantitative Trait Locus in Experimental Crosses

open access: yesJournal of Probability and Statistics, 2009
Current methods for mapping imprinted quantitative trait locus (iQTL) with inbred line crosses assume fixed QTL effects. When an iQTL segregates in experimental line crosses, combining different line crosses with similar genetic background can improve ...
