Pea-comb phenotype in chickens
Pea-comb is a dominant mutation in chickens that drastically reduces the size of the comb and wattles. It is an adaptive trait in cold climates as it reduces heat loss and makes the chicken less susceptible to frost lesions. Here we report that Pea-comb is caused by a massive amplification of a duplicated sequence located near evolutionary conserved non-coding sequences in intron 1 of the gene ...
متن کاملMorphometric Traits and Correlation between Body Weight and Body Size Traits in Isa Brown and IlorinEcotype Chickens
Data collected in 2012 on 400 chickens were subjected to two-way analyses of variance to estimatebody weight, morphometric traits as well as the correlationbetween body weight and morphometric traitsin Isa Brown and Ilorin ecotypechickens. The studied morphometric traits were comb length, beak length,head length, neck length, body length, wing length, shank length, thigh length, toe length, bre...
متن کاملResponse to selection for body weight and egg weight in chickens.
W E L L conducted selection experiments are useful in testing the validity of modern selection theory. Observed genetic changes from selection frequently show poor agreement with expectation. The relationship of selection to the genetic variance composition of a population, to correlated responses, to plateaued populations and to selection limits are problems not yet well understood. This study...

متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
