HGT in Eukaryotes

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

Horizontal gene transfer occurs in eukaryotes too, though less often than in prokaryotes, since eukaryotic sex cells are more protected from direct environmental exchange.

Show

Certain aphids acquired fungal genes for pigment production through horizontal gene transfer, most likely while consuming fungi as food.

Watch for

Horizontal gene transfer in eukaryotes is documented but comparatively rare — most inheritance still follows ordinary parent-to-offspring transmission.
