Hybrid tea flowers are well-formed with large, high-centred buds, supported by long, straight and upright stems. Each flower can grow to 8-12.5 cm wide. Hybrid teas are the world's most popular type of rose by choice due to their color and flower form.Their flowers are usually borne singly at the end of long stems which makes them popular as cut flowers.ach flower can grow to 8-12.5 cm wide.

Gene Pool, Alleles and Variation in the Population. Genes have many different forms (alleles). This forms the basis of the study of population genetics. Populations are made up of members of the same species which interbreed.ecombination (Crossing Over). This is the exchange of genetic material between adjacent chromatids on the homologous chromosomes. This random exchange of DNA results in many new combinations of alleles on chromosomes, creating great potential for variation.
DNA is a lengthy double helix bearing many genes that are the genetic training used for the functioning and progression of an organism. Different forms of a gene, which may give rise to different phenotypes, are known as alleles. homozygous. gene variations. Mutations! no...
