[Comparative cytogenetic study of the tetraploid Matricaria chamomilla L. and Matricaria inodora L]
Abstract:
A comparative cytogenetic study of the autotetraploid breed of Matricaria chamomilla L. (M. recutita L.) and Matricaria inodora L. was carried out by DAPI-banding, fluorescent hybridization in situ (FISH) with 26S and 5S rDNA probes, and analysis of meiosis. All chromosomes were identified in both karyotypeson the basis of DAPI-banding images and 26S and 5S rDNA distribution, and species-specific idiograms were composed for both M. chamomilla and M. indora taking into account the polymorphous variants of DAPI-banding images, showing the location of the 26S and 5S rDNA sites.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...
Chi-square Analysis
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...
