Question

How was it possible to prove hybridization between two plant species?

Answer 1

Hybridization is the process of crossing two genetically different individuals to result in a third individual with a different, often preferred, set of traits. Plants of the same species cross easily and produce fertile progeny. ... Inheritance studies require crossing plants with contrasting or complementary traits.

Plant hybridization is the process of crossbreeding between genetically dissimilar parents to produce a hybrid. It frequently results in polyploid offspring.

The Helianthus hybrid species provide the most detailed analysis of ecological differentiation contributing to homoploid hybrid speciation. The most recent advance in the study of hybridization is the use of genetic and genomic data to detect signatures of hybridization in wild populations.

Gregor Mendel (1822–84) is considered the "father of genetics". His experiments with plant hybridization led to his establishing laws of inheritance. Genetics stimulated research to improve crop production through plant breeding.

hybridization can be summarised as follows-

If a species A is to be transformed into a species B, both must be united by fertilization and the resulting hybrids then be fertilized with the pollen of B; then, out of the various offspring resulting, that form would be selected which stood in nearest relation to B and once more be fertilized with B pollen, and so continuously until finally a form is arrived at which is like B and constant in its progeny. By this process the species A would change into the species B
