In two of these regions, the differences were attributable to
alternative alleles of just one gene: teosinte glume architecture (tga1) and teosinte branched (tb1), which affect kernel structure and plant architecture.
Not exact matches
Using Atlantic killifish (Fundulus heteroclitus), the researchers examined whether mitochondrial - nuclear interactions alter the frequency
of alternative forms
of a gene that arise by mutation, called
alleles, for over 11,000 nuclear DNA sequence variations within a population
of the fish with mixed ancestry.
I do like that the authors performed RNA - Seq
of the transcriptome, which provides insights into mechanisms like
alternative splicing (AS),
allele - specific expression (ASE), and RNA editing.
Additionally, we found that CGG10023 carried the
alternative allele at ACN9 homologue (S. cerevisiae; ACN9), CKM, and COX4 / 1, all
of which are associated with increased winning performance in modern race horses (37, 38).
Exceptions included the ZFAT gene, which is associated with variation in wither height (36), for which both ancient individuals carried a mixture
of reference and
alternative alleles.
Allele one
of several forms
of a gene that determines
alternative forms
of one or more genetic traits.
As part
of their study
of genetics, students in Shannon Dziwanowskis seventh - grade science class at Csar Chvez Academy Middle School in Detroit, Michigan, spend the first minutes
of class reviewing a worksheet on dominant and recessive
alleles, which are
alternative forms
of genes.
Doing a genetic test and subsequently eliminating an individual from the breeding population may not be the best strategy, as by targeting a particular
allele at one genetic locus for removal from the gene pool
of a particular breed, breeders may in fact increase
allele frequency
of genetic variants on
alternative haplotypes at the same, or a different locus, that are recessively deleterious.
