Genetic Analysis of Two Chromosome Interchanges I N Barley from F 2 Data '
HE use of backcross data for the genetic analysis involving an interchange T between two non-homologous chromosomes has been clearly defined and reviewed. JOACHIM (1947) has presented tables to facilitate the use of the product method for the analysis of Fz data involving semisterility. In a selfpollinated plant such as barley, this method presents a convenient tool for the determination of lin...
متن کاملChromosomal Interchanges in Maize.
Chromosomal interchanges, or reciprocal translocations, in maize are of primary interest because of the opportunities they offer for the study of chromosome behavior and crossing over. The great volume of work which has been done on crossing over and on translocations in Drosophila has yielded an abundance of statistical data on crossing over and chromosome distribution. For this type of work D...
متن کاملInterchanges and statistical designs
Let D be a statistical design consisting of v varieties on b blocks. We say it is binary if a variety occurs at most once on every block. For varieties p and q on blocks x and y respectively, we can obtain design D' from D by interchanging p and q (so p is on y and q is on x). We say that the exchange is binary if either x y, or p q, or: q not on x and p not on y. If D is binary then D' is also...
متن کاملFloristic Interchanges Between Formosa and the Philippines
THE FLORAS of Formosa and the Philippines are, in spite of the ir geographic proximity , distinctive in their general nature. The tw<? regions wereseparated by the Formosan rift (the Bashi Channel), probably in the early Tertiary, long' before their connections with other respective neighboring areas were severed. Thus the bulk of the Formosan flora was derived from China or from other floras t...
متن کاملEvaluation of Alternative Intersections and Interchanges
Diverging diamond interchanges (DDIs) have been growing in usage over the past few years and have gained considerable attention and interest. The advantage of the DDI over a conventional diamond interchange is that DDIs eliminate the need for left turn phases at the two intersections of the diamond, while occupying roughly the same geometric footprint as the conventional diamond. At the beginni...
