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

Trends 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 Crosses and Linkage Mapping in Schistosome Parasites [PDF]

Trends in Parasitology, 2018
Linkage mapping - utilizing experimental genetic crosses to examine cosegregation of phenotypic traits with genetic markers - is now 100 years old. Schistosome parasites are exquisitely well suited to linkage mapping approaches because genetic crosses can be conducted in the laboratory, thousands of progeny are produced, and elegant experimental work ...

Cryptococcus neoformans Mating and Genetic Crosses [PDF]

Current Protocols in Microbiology, 2019
AbstractThe Cryptococcus pathogenic species complex is a group of opportunistic human fungal pathogens that cause cryptococcal meningoencephalitis, an infection associated with unacceptably high mortality rates. The public health relevance of these pathogens has galvanized extensive research over the past several decades and led to characterization of ...

Genetic evaluation of Ethiopian Boran cattle and their crosses with Holstein Friesian in central Ethiopia: milk production traits

Animal, 2009
Breed additive and non-additive effects, and genetic parameters of lactation milk yield (LYD), 305-day milk yield (305YD), lactation length (LL), milk yield per day of lactation (DM) and lifetime milk yield (LTYD) were estimated in Ethiopian Boran cattle

Genetic crosses within and between species of Cryptosporidium

Proceedings of the National Academy of Sciences of the United States of America, 2023
Significance The parasite Cryptosporidium is a leading cause of diarrheal disease. While infection is common worldwide, young children experiencing malnutrition are impacted most profoundly, and the disease is an important contributor to early childhood ...

Multi-trait Improvement by Predicting Genetic Correlations in Breeding Crosses

G3: Genes, Genomes, Genetics, 2019
The many quantitative traits of interest to plant breeders are often genetically correlated, which can complicate progress from selection. Improving multiple traits may be enhanced by identifying parent combinations – an important breeding step – that ...

GENETIC RECOMBINATION IN SEXUAL CROSSES OF PHYCOMYCES

Genetics, 1975
ABSTRACT Sexual crosses between strains of Phycomyces blakesleeanus, involving three auxotrophic and one color marker and yielding a high proportion of zygospore germination, are described. Samples of 20-40 germ spores from 311 individual fertile germ sporangia originating from five two-factor and three three-factor crosses were ...

Multi-parent populations in crops: a toolbox integrating genomics and genetic mapping with breeding

Heredity, 2020
Crop populations derived from experimental crosses enable the genetic dissection of complex traits and support modern plant breeding. Among these, multi-parent populations now play a central role.
