Genetic Variation in Plant Species Genetic variation in plant species is a crucial aspect of their survival and evolution. Plants, like all living organisms, have genetic material that determines their characteristics and traits. This genetic material can vary within a plant species, leading to ...
In vitro regenerated sunflower (Helianthus annuus L.) plants (R1) were self-fertilized and the R2 generation was evaluated for qualitative traits. A broad range of phenotypic variation was observed and mutation frequencies were calculated. Some in vitro induced variant phenotypes were similar to ...
Industrial pollution caused by humans ___ the genetic variation of plants in nearby areas, which may further affect plant evolution. A. increases B. decreases C. maintains D. eliminates 相关知识点: 试题来源: 解析 A。解析:人类造成的工业污染会给植物带来新的环境压力,这可能会增加(increases)植物...
Conservation of genetic variation in plants—the importance of population size and gene flow. In L. Hansson, ed. Ecological Principles of Nature Conservation: Applications in Temperate and Boreal ... L Hansson - Elsevier Applied Science 被引量: 61发表: 1992年 The population genetic consequences ...
We found that treehopper male signals varied according to the clone line on which they developed, showing that genetic variation in host plants affects male treehoppers' behavioural phenotypes. This is the first demonstration of cross-trophic indirect genetic effects on a sexually selected trait. We...
A. High genetic variation among offspring B. The need for two different plants to start the process C. Offspring are genetically identical to the parent D. Involvement of pollination 相关知识点: 试题来源: 解析 C。解析:植物无性繁殖的一个特征是后代与亲本在基因上相同。选项A,无性繁殖后代基因变...
Why do plants show genetic variation? A. Because they all grow in the same place. B. Because they are all the same species. C. Because they have different genes. D. Because they look the same. 相关知识点: 试题来源: 解析 C。选项 A 都长在同一个地方不会导致遗传变异;选项 B 是同一...
We show that this information is paving the way towards a more complete understanding of the heritable basis underlying population epigenomic variation. We also highlight important conceptual challenges when interpreting results from these genetic studies, particularly in plants, in which epigenomic ...
Context-specific regulatory variants in precision medicine and agriculture Lingzhao Fang recalls how a 2002 paper by Brem et al., which investigated the genetic basis of natural variation in gene expression in budding yeast, and the GTEx atlas of genetic regulatory effects across human tissues inspir...
What can cause genetic variation in animals and plants? A. 白科经列万存收白科经列万存收Living in the same place.白科经列万存收白科经列万存收 B. 细今圆统集感土出决细今圆统集感土出决Having the same parents.细今圆统集感土出决细今圆统集感土出决 C. 保却拉重七必气党内治往该改林...
