Population genetic structure of <i>Pseudo-nitzschia multistriata</i> parental strains and samples of their F1 offspring [21] as identified by Structure.

Abstract

<p>For each cross, parental and F1-strains are grouped in boxes, ordered along the x-axis. Each vertical bar in a box represents one strain; the first two bars represent the parental strains, the remainder, the F1 strains. The y-axis indicates the proportion of a strain’s genome assigned by Structure to POP_A (green) and POP_B (red). Strains not assignable to one of these populations at or above the 0.9-probability-level are considered putative hybrids based on the Structure results. Parental strain assignment according to Structure: Cross 1: SY017 (POP_A; green)×SY278 (hybrid); Cross 2: SY017 (POP_A; green)×SY138 (POP_B; red); Cross 3: SY138 (POP_B; red)×SY378 (POP_B; red); and Cross 4: SY138 (POP_B; red)×SY379 (POP_B; red).</p
