      The historical increase in within-era differentiation is associated with clear shifts in direct ancestry, which we define on the basis of haplotype sharing with lines from the same era and before ().Direct ancestry from earlier (public) lines, although still common in eras 1 and 2, is rare in era 3, in which most ancestry is traced to other (proprietary) era 3 lines (Fig. 2B).Cited by: Abstract– Allozyme and mitochondrial DNA (mtDNA) data were obtained from pink salmon throughout Prince William Sound, Alaska, from two hatchery, five upstream, and 20 tidal locations distributed among five management regions collected during Screening for allozymes included 66 loci for 92 to fish per sample. Thirty‐four loci had variant allele frequencies Cited by:

    Our results showed that small but significant variation exists among and within sources. Stuber and Goodman () analyzed allozyme data for popular and historically important maize inbreds and reported that they could differentiate three of the 10 lines . Maize, Zea mays L. spp. mays, is a diploid (2n= 20) levels of development do not exist, the farmer has member of the tribe Maydeae, Tripaceae, or Andropo- played an important role in the evolution of the kinds neae (depending upon one's taxonomy), subfamily of maize being grown.

      Since the advent of modern plant breeding in the s, North American maize has undergone a dramatic adaptation to high-input agriculture. Despite the importance of genetic contributions to historical yield increases, little is known about the underlying genomic changes. Here we use high-density SNP genotyping to characterize a set of North American maize lines spanning the history Cited by:   The domestication of maize (Zea mays ssp. mays), ~10 years ago in Mexico involved radical phenotypic differences from its progenitor, teosinte (Z. mays ssp. parviglumis). Because of drastic changes in growth habit and the shape, dimensions, and accommodation of seeds in the ear, maize has to be seen as an extreme case of by: 3.

Sweet corn (Zea mays L.) is one of the most popular vegetables in the USA and its popularity is increasing in Asia and Europe. In the USA the farm value of sweet corn for processing ranks second only to tomatoes.

Maize (Zea mays L.) is one of the most-important food crops in southwestern China. Corn was domesticated through hundreds of generations; wild maize cobs became larger over time, with more rows of kernels, eventually modified to the corn we farm today ().In fact, the degree of genetic alteration has converted corn from a wild plant—its progenitor commonly believed to be teocintle (Zea mexicana (Schrad.)Kuntze)—into a plant that is totally dependent upon humans for Author: José Luis Cabrera-Ponce, Eliana Valencia-Lozano, Diana Lilia Trejo-Saavedra.

They are in popular usage because the variation for these markers is ubiquitous and this variation can be understood in genetic terms. Most advances in varietal descriptions will involve the use of DNA as a by: Effects of maternal genotypes for eight enzyme loci on seven quantitative traits in 41 half-sib families were determined.

Heritability estimates for the quantitative traits were highly significant and ranged from to Only six of comparisons Cited by: In corn R is a gene for red aleurone; its recessive allele r determines colorless aleurone. A cross is made between a diploid r/r female and a trisomic R/r/r male.

If pollen grains with extra chromosomes are inviable, the ratio of red to colorless kernels expected in the progeny would be. Allozymes have been applied in many population genetics studies, including measurements of outcrossing rates, (sub)population structure and population divergence.

Allozymes are particularly useful at the level of conspecific populations and closely related species, and are therefore useful to study diversity in crops and their relatives.Normal wild-type mice have coats with a dark overall pigmentation.

A mutation called yellow shows a curious inheritance pattern. If a yellow mouse is mated to a homozygous wild-type mouse, a ratio of yellow to wild-type is always observed.Genotype. An organism's genetic makeup, or allele combinations.

Phenotype. An organism's physical appearance, or visible traits. dominant allele. An allele whose trait always shows up in the organism when the allele is present. Recessive. An allele that is masked when a dominant allele is present.
