Sequence analysis

... the gene and compare this with the amino acid sequences of known proteins (in a database). I has about 200 results of related proteins. The more identities and positives a protein of comparison has, the fewer gaps and the higher the score. Scores are reduced by mismatches and gaps in the best ...

Determining (P) plants from F2 data

... plants were crossed in the same manner, to form F2 generation offspring. The task is to use the ears from these F2 individuals to figure out the identities of the origonal parental (P) plants. 1. What do you observe about the F2 corn ears. 2. Try to pick two types of characteristics which are ...

BLAST

... sequence searches via BLASTn: I have a subject sequence containing two HSPs with the following statistics Score = 276 bits (149), Expect = 4e-70 Identities = 149/149 (100%), Gaps = 0/149 (0%) Strand=Plus/Plus and... Score = 156 bits (84), Expect = 6e-34 Identities = 84/84 (100%), Gaps = 0/84 ...

Re: Brain size=IQ level theory (Blacks vs Whites & Asians)

... it was well documented that Lewontin had been wrong. Practically every analysis of genetic markers demonstrated the biological reality of racial identities. In one of them, conducted by Tang, Quertermous, and Rodriguez, et. al., in 2005, all except five of 3636 test subjects (including Asians, ...

BLAST

zami: the e-value does not depend only on the identities, but also on length of the chain. If you had 100% identical 10-bases long chain or 99% identical 350-long chain, when do you think, you will have lower e-val? Second, what about to let him ...
