What happened in Mendels experiments when a pea plant received two different alleles for the same traits?
When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
What happened in Mendel's experiments when a pea plant received two different allele's for the same trait?
When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
What is the significance of Plant Breeding?
Plant breeding brings improvement in quality and quantity of production in plants by improving their genome.
Why is it important that Mendel began with purebred plant?
The correct term is "true-breeding". What that means is that if he takes his two pea plants with white flowers and breeds them together, he will always get a pea plant with white flowers. Something that is true-breeding for a particular trait is homozygous, i.e. if the allele for red flowers is R and the allele for white flowers is w, then a true-breeding white flowering plant is ww, and true-breeding red flowering plant is RR. If you cross-breed a true-breeding red flowering with a true-breeding white flowering plant, you would get 1/4 of the offspring as true-breeding red flowers, 1/4 of the off-spring as true-breeding white flowers, and 1/2 the offspring as heterozygous (not true-breeding) red flowers - Rw. If you don't start with true-breeding plants - say you start with Rw and ww (a red and a white plant) you get 1/2 the offspring heterozygous red, and 1/2 true-breeding white. Thus if you didn't know anymore, you would assume that half the time when you breed a red and a white plant, you would get a red plant, and half the time a white, which is incorrect. Furthermore, if you conducted the experiment again, say with RR and Rw, you would get a different result (in this case, all red). By starting with plants that are true-breeding, you ensure that you get the same results that properly show how the traits are passed on.
What is used to improve the phenotype of plants?
Plant breeding
Do genetics from the seed come from the plant?
Usually, yes. In evolution and conventional breeding practices, the genetics in the seed do come from the parent plant (vertical breeding). When plants are genetically modified using genetic engineering, the genetics in the seed often contain genes from an organism that is a different species, often a bacteria, that is completely different than the genes in the parent plant (horizontal breeding).
What is mass selection in plant breeding?
because mass selection is crossing plants with desirable traits , controlled breeding is mating organism to produce offspring with certain traits DESIRABLE TRAITS = CERTAIN TRAITS so mass selection is consider a form of controlled breeding
