Information about the Western Society of Weed Science annual conference held in Hawaii in 2010 is presented. Topics centered on the future herbicide resistant traits in crops and the resistance management. The conference featured several product and technology development managers including David Saunders,...
A trait may be very pronounced, barely noticeable, or in between. Various factors, including genetic makeup, exposure to harmful substances, other environmental influences, and age, can affect expressivity. Both penetrance and expressivity can vary. People with the gene may or may not have the ...
How many pairs of autosomes do humans have? How many chromosomes in gibbon sex cells are autosomes? How many chromosomes are in trisomy 21? How many chromosomes do penguins have? How many alleles are there for a Mendelian trait? How many genes contribute to autoimmunity?
Interestingly, many genes and genetic pathways are shared between both developing novel traits derived from median fins: the sword and the gonopodium. Our analyses show that a larger set of gene networks was co-opted during the development and evolution of the "older" gonopodium than in the ...
How many alleles do polyploids have? How many alleles for hemophilia do males have? How many genes do you share with your parents? How many autosomal chromosomes come from each parent? How many alleles for a given trait are present in a typical body cell?
Some organisms have a long haploid phase, resulting in strong haploid purifying selection acting to maintain gene activity on the Y chromosome70,83,84. In species where haploid selection is more limited, many genes on the Y or W chromosome are sheltered in the diploid phase by the copy on ...

The "short" version, in many cases, has a less active form of one of the enzymes involved in the synthesis of the hormone, so the plants are shorter. We refer to two genes as alleles of each other when they are inherited as alternatives to each other. In molecular terms, alleles are...
A haplotype isa group of genes within an organism that was inherited together from a single parent. The word "haplotype" is derived from the word "haploid," which describes cells with only one set of chromosomes, and from the word "genotype," which refers to the genetic makeup of an orga...
从个体发生角度而言, 鳍两性异形是由多基因造成的, 受控于不同的数量性状位点(quantitative trait loci, QTL)[108,109]. 目前发现, 性别偏向基因(sex-biased genes)以及受其影响的与生长、性别分化相关基因在两性之间不同的表达水平, 或许最终造成了两性特异的性征[83,110~118]. 对青鳉鱼雄性臀鳍鳍条上乳突状结...
