WebApr 19, 2016 · The most obvious interpretation of a genetic correlation is that it arises as a result of pleiotropy [1]–alleles that affect one trait on average also have an affect on a second trait. This intepretation can … WebAn insight of genetic diversity and correlation among the various traits related to yield is helpful in this regard.

WebThe squared correlation based on genotypic allele counts is therefore not identical to the r-sq as estimated from haplotype frequencies (see above), although it will typically be very similar. Because it is faster to calculate, it provides a good way to screen for strong LD. The estimated value for the example in the section above (rs2840528 ...
