Part b - gene linkage and phenotypic ratios
WebExpected Results if Linkage Occurs. Expected Results if Linkage Occurs - Coupling. If two genes are linked, the gametic and phenotypic arrays can no longer be obtained by multiplying the individual arrays for each gene . However, we can still develop mathematical tools to do this. Consider a cross between two homozygous individuals. WebWhen a gene is sex-linked the phenotypes are not spread evenly across the sexes. In the case of a gene that causes a sex-linked disease, one sex will be disproportionately …

WebThe Arina/Cezanne linkage map had 54 linkage groups. The A, B and D genomes had 1429.0, 1298.6 and 925.9 cM map length, respectively (Supplementary Table S1). The D genome was the least saturated of the three genomes. The Arina/Cezanne linkage map covered a genetic distance of 3853.5 cM, with a density of at least 1 marker per 0.52 cM. WebDrought is one of the most detrimental abiotic stresses hampering seed germination, development, and productivity. Maize is more sensitive to drought than other cereals, especially at seedling stage. Our objective was to study genetic regulation of drought tolerance at germination and during seedling growth in maize. We evaluated 420 RIL with …
