主要方法:
- 在X和Y染色体之间识别了高度保守的性别标记物CsPDS5.
- 开发一种用于确定性别的单对初始PCR试验.
- 在14个大麻品种和6个交叉品种的500多个样本上验证PCR方法,使用各种组织和发育阶段.
主要成果:
- CsPDS5标志物和开发的PCR试验在性别基因定型中显示出100%的准确性.
- 这种方法可以在开花之前进行早期的性别识别,区分雄性和雌性大麻植物.

02:45The Ratio of X Chromosome to Autosomes
8.8K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...

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...
