RES Congress No. 14

I replied that no matter what, they get there. But this, I think, from the category of "the fool himself" was the answer. Rasnitsyn is the smartest man, and Lukhtanov is still growing up and growing up.

Just imagine - they get hit occasionally. The image shows mitochondrial gene heterogeneity in a P. tsvetaevi specimen. Arrows show some positions. M. Wiemers also came across similar individuals in the North a couple of times. Africa.

Here the question is different. Is a couple of times enough for speciation of a hybrid?

These are different questions. Mitochondrial heterogamy is a unique phenomenon and does not indicate the frequency of hybridization.
But nuclear heterogamy is extremely common in some tropical "Eliot sections". There are at least 1/4 individuals of hybrid offspring. This even interferes with the work - you need to look for another individual with a "clean" genome.

A couple of quick examples: ITS2 - shift of the reading frame in one of the alleles; Ef-1a-heterozygous alleles.

I want to say that the mitochondrial gene was included in vain as proof of hybrid speciation. This is a clear mistake in the methodology.

Not quite. For example, our Eastern European P. bellargus are products of hybridization with P. coridon. Western bellargus have completely different mitochondrial genes than our own, our own have mitochondria close to Corydon's. And our nuclear and Western populations are the same. That is, our bellargus populations at some historical moment passed the "bottleneck" and used corydon females for self-support. Over time, the Corydon legacy in nuclear genes was washed out, but the mitochondrial legacy remained due to the isolation of the mitochondrial genome, although it has already acquired a few mutations of its own (about 0.5-0.7% of the corydon). By the way, apparently due to ancient hybridization, eastern populations also have high morphological variability: blue male forms, darkish-blue forms, and even more exotic ones. And this is in addition to direct new hybrid individuals (polonus form).

Yes, genetics is full of exceptions )))
