The life history of Yucca glauca in the Great Plains was the subject of a four year field study. Data were incorporated in a stage transition model (based on rosette size) to explain how populations ...

The mechanism by which liverwort (Marchantia polymorpha) asexually reproduces via the development of clonal progenies (gemmae) has been revealed by a cross-institutional research group. They ...

Plant reproduction is highly complex and variable across the kingdom. The emergence of sexual reproduction has contributed to increase plant genetic diversity and enabled the colonisation of new ...

Asexual, or vegetative, reproduction in plants is controlled by environmental conditions, but the molecular signaling pathways that control this process are poorly understood. Recent research suggests ...

The study reveals how Balanophora plants function despite abandoning photosynthesis and, in some species, sexual reproduction. Their plastid genomes shrank dramatically in a shared ancestor, yet the ...

Seeds are the end product of plant reproduction. Whether directly as food, or indirectly as animal feed, they provide around 80 percent of human calorie consumption. In the millennia since humans ...

Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, ...

Not all creatures need to breed to produce offspring. Animals like zebra sharks and killifish are redefining what scientists thought they knew about asexual reproduction. Among vertebrates, or animals ...

Examples of organisms that use asexual reproduction include: In humans, each gamete has half the total of 46 chromosomes that the body requires. We refer to 23 chromosomes within a gamete as haploid.

Sexual reproduction involves the fusion of the nuclei of a male and female sex cell during fertilisation. The offspring inherit a mixture of alleles from both parents. Unlike sexual reproduction, ...
