Fig. 2: Analysis of female and male COs in Col, Ler, and F1 hybrid populations.
From: The megabase-scale crossover landscape is largely independent of sequence divergence
A, B The numbers of COs per gamete in each replicate population of Col and Ler, respectively. Each letter corresponds to one F1* plant (Fig. 1). The two-sided Mann–Whitney test was used to evaluate the differences in CO numbers between female and male meiosis. The p values for Col replicate A, B, E, F are 4.9e−12, 2.5e−12, 4.7e−06 and 1.9e−04, respectively. The p values for Ler replicate D–G are 5.6e−06, 6.7e−05, 6.8e−05 and 2.6e−05, respectively. In the boxplot, the centre line indicates median, the bounds of box indicate 25th and 75th percentiles, the whiskers indicate 1.5 * IQR (IQR: the distance between the first and third quartiles). C Distribution of CO number per gamete in female and male meiosis of Col, Ler and F1 hybrids. The mean number of COs are colour-coded and indicated by dashed lines. The sample sizes are indicated in parentheses. D–F The chromosomal distribution (sliding window-based, window size 2 Mb, step size 50 kb) of COs in female and male meiosis of Col, Ler, and F1 hybrids, with 90% confidence interval. The genome-wide mean level of recombination is shown with dashed lines. The pericentromeric and centromeric regions are indicated by grey and blue shading, separately. The ~1.2 Mb inversion between Col and Ler on chromosome 4 is indicated by a red bar. Source Data are provided as a Source Data file.
