Fig 1.
The average length of flagella of sperm from males of two different lineages in Astyanax mexicanus and their hybrids.
Each circle represents the average length of measured sperm from a single male. Sample sizes are given in S1 Table. The New lineage is represented by “a” (cave fish) and “b” (surface fish). Purebred Old lineage is represented by “e” (cave fish). Hybrids between old and new lineage fish (“c”) are intermediate in flagellar length. Hybrids between two old lineage cave populations (“f”) cluster with pure bred Old lineage cave fishes. Hybrids that contain three doses of Old lineage and one dose of New lineage (“d”) are intermediate between Old:New 1:1 hybrids (“c”) and Old lineage fish (“e” and “f”). Individual values in column d were dithered to make them more easily distinguished. Details are in S1 Table.
Table 3.
Variability of some sperm phenotypes is positively correlated with genetic variability among sperm haploid genotypes.
Fig 2.
Significant relationships between sperm behavior as quantified by CASA and heterozygosity.
Plotted are coefficients of variation (CV) in WOB at 20 and 30 seconds, LIN at 20 seconds and PROG at 30 seconds, against expected heterozygosities of the male sources of the sperm.
