Table 2.
Mean Number of MLH1 Foci per Cell and Standard Deviation (SD) Calculated over the Individual Means and the Estimated Number of Crossovers (COs) per Chromosome Pair.
| Species | N | n | Mean Number of MLH1 Foci/Cell | SD | Chromosome Pairs | COs/Chromosome Pair | Chromosome Type | COs/Chromosome Arm |
|---|---|---|---|---|---|---|---|---|
| Dog | 6 | 184 | 38.89 | 0.87 | 39 | 1.00 | Acrocentrica | 1.00 |
| Wolf | 2 | 45 | 40.94 | 1.61 | 39 | 1.05 | Acrocentrica | 1.05 |
| Goat | 6 | 109 | 61.24 | 4.03 | 30 | 2.04 | Metacentric | 1.02 |
| Ibex | 6 | 119 | 64.74 | 1.08 | 30 | 2.16 | Metacentric | 1.08 |
| Sheep | 6 | 125 | 63.47 | 3.42 | 27 | 2.35 | Metacentric | 1.18 |
| Mouflon | 5 | 113 | 69.03 | 2.49 | 27 | 2.56 | Metacentric | 1.28 |
Note.—N, number of individuals; n, total number of spermatocytes for which MLH1 was counted. Means calculated over all measurements were almost identical (not shown).
aAll autosomes are acrocentric.
