![]() ![]() A total of 125 simple sequence repeat (SSR) markers were used to genotype the two F2 interspecific populations. 3-79 as parents to study hybrid breakdown in cotton. In the current study, two reciprocal F2 populations were developed using Gossypium hirsutum cv. But correlations between genomic heterozygosity and vegetative and reproductive traits in cotton interspecific populations have not been studied. Relationships between genomic heterozygosity and traits-fitness have been extensively explored especially in the natural populations. Hybrid breakdown has been well documented in various species. Genomic heterozygosity and hybrid breakdown in cotton (Gossypium): different traits, different effects.ĭai, Baosheng Guo, Huanle Huang, Cong Zhang, Xianlong Lin, Zhongxu The classic form of the Neo-Darwinian argument hypothesizes that heterozygosity confers genetic homeostasis (Lerner, 1954) i.e., multiple, molecular forms of the same enzyme endow the organism with a broader range of tolerance to environmental variation because different forms may. The connection between fitness and heterozygosity has eluded geneticists for decades. The relation of growth to heterozygosity in pitch pineį. ![]()
