概括

生殖隔离中的不对称性不能预测植物物种之间侵入的方向. 进一步的研究应该集中在混合健身和生态因素上,以了解内进模式.

科学领域:

进化生物学是进化的生物学.
植物物种化植物物种化
遗传学是一个遗传学.

背景情况:

生殖隔离 (RI) 通过减少跨物种杂交来维持物种界限.
RI和内向的不对称性在混合植物种群中很常见.
了解内进方向对于进化研究至关重要.

研究的目的:

调查完全生殖隔离中的不对称性是否预测自然杂交植物内进的方向.
使用元分析分析分析不对称RI和不对称内向的关系.

主要方法:

进行了对19种植物物种对进行的元分析,并提供了关于不对称总RI和内进的数据.
进行了全面的文献审查,以确定相关研究.
使用双尾二项式测试来评估RI不对称性和内向方向之间的关联.

主要成果:

在总生殖隔离和内进方向的不对称性之间没有发现显著的关系 (p = 0.3593).
不对称的生殖隔离不能可靠地预测通过内进的遗传物质转移的方向.

结论:

不对称的RI不是植物内进方向的强有力的预测指标.
内进模式最好通过诸如混合健身,交配行为以及混合区内的生态/人口影响等因素来解释.

关键词:

不对称的内向侵略不对称的生殖隔离.基因流是指基因的流动.混合区混合区混合区混合区自然的杂交,自然的杂交.植物物种化植物物种化.

What is a Species?

What is a Species?

Genetics of Speciation

Genetics of Speciation

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

Formation of Species

Formation of Species

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

Asexual Reproduction

Asexual Reproduction

Asexual reproduction allows plants to reproduce without growing flowers, attracting pollinators, or dispersing seeds. Offspring are genetically identical to the parent and produced without the fusion of male and female gametes.

Gene Flow

Gene Flow

Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.

Law of Segregation

Law of Segregation

When crossing pea plants, Mendel noticed that one of the parental traits would sometimes disappear in the first generation of offspring, called the F1 generation, and could reappear in the next generation (F2). He concluded that one of the traits must be dominant over the other, thereby causing masking of one trait in the F1 generation. When he crossed the F1 plants, he found that 75% of the offspring in the F2 generation had the dominant phenotype, while 25% had the recessive phenotype.
