Modeliranje evolucije barve cvetov pri navadnem odolinu

 

Vrste se često delijo na jasno razmejene populacije, ki jih ločijo ozke cone, v katerih pride do hibridizacije. Te cone lahko modeliramo z reakcijsko-difuzijskimi enačbami, s katerimi se dokopljemo do ocen količin, kot sta jakost izbora in hitrost difuzije genov. Populacijsko genetiko hibridnih con bomo ilustrirali z nedavno študijo, v kateri smo obravnavali populacije navadnega odolina (Antirrhinum) v Pirenejih, ki se med seboj razlikujejo po barvi cvetov. 

Predavanje bo v angleščini.

Lepo vabljeni!

Modeling the evolution of flower colour in snapdragons

 

Species are often subdivided into distinct populations, which are separated by narrow zones of hybridisation. These can be modelled using reaction-diffusion equations, yielding estimates of quantities such as the strength of selection and the rate of diffusion of genes.  I will illustrate the population genetics of hybrid zones using our current study system, which involves populations of Antirrhinum (snapdragons) in the Pyrenees which differ in flower colour.

 

Cordially invited!
