6 dni temu · Crossing over is an extremely important mechanism for increasing genetic diversity in animals. The frequency with which crossing over occurs between any two linked genes is proportional to the distance between them.
3 dni temu · These matrices capture the pairwise dissimilarities or distances between objects, making PCoA particularly valuable in fields like ecology, genetics, and social sciences where relationships are often expressed as distances rather than direct measurements.

4 dni temu · Abstract: Let $T = ([n], E)$ be a tree and let $D = ( d(i,j) )_{i, j \le n}$ be the distance matrix of $T$. Let $S\subseteq [n]$. We give the first combinatorial proof for a formula to compute the principal minor of $D$ indexed by $S$, namely $\det D[S]$.
