How to improve the inheritance of pigeons, selection or crossbreeding?
whats most important traits we study? Can we use molecular markers in enhancement? What is the suitably markers we use?
Dear Dr Esteftah ElKomy,
greetings, many thanks for your question. It is interesting to answer for your question from breeders "plant breeding" point of view.
I think if you have a wide population you can select first individuals "selection"
Then try make wide crosses between them and neglect the self crossing as make inbreeding depression "you will face low yield and growth"
and try select for economic traits that important for consumers
DNA markers is the best tools and you need to select the MAS marker assisted selection i.e,. SSRs, SNPs, ESTs
for enhancement the DNA markers I think you could find that in previous work.
with best regards

Dear Esteftah
The method of breeding depends on the estimation of the heritability of the desired trait, hence the high heritability traits ( important additive gene effect ) can be improved by phenotypic selection.
In the case, there are large difference between broad and narrow heritability that refers to the importance of the dominance action gene, can be improved by mating system
Good Luck
What kind of trait would you like to breed. I have seen aggressive chicken in tel-Aviv. usually aggression goes with other good qualities. Here is from the rodent perspective:
