Genetics of Ascospore Color in Sordaria lab

Introduction:To achieve genetic experiments with haploid organisms, genetic strains of different genotypes must be crossed f ... s). Inside the asci, karyogamy occurs and combines the two parental genomes, and then meiosis forms genetically diverse ascospores. Eight ascospores can be found lined up in a row in the asci; they fo ... he asci; they form a single zygote, which is diploid.These arrangements provide scientists to study genetic recombination. The genetic differences between mycelia grown form ascospore taken from one a ...
