WebbPlants have a a transport system. Water, food and ions are transported by the xylem and phloem in a plant. The xylem transfers water and mineral ions. The xylem is a vascular bundle that transports water and ions to the leaf. This occurs through the process of transpiration. The phloem transfers food. WebbWhat was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants? (1) There is considerable genetic variation in garden peas. (2) Traits are inherited in discrete units, and are not the results of ʺblending.ʺ (3) Genes are composed of DNA. (4) An organism that is homozygous for many recessive traits is at a …
WebbOne major reason that organisms who reproduce sexually have variation is because each individual has a different combination of genes inherited from their parents. But, there is still some variation in variation as is clearly evident in siblings who have the same parents but inherit different genes making them genetically different from one another. WebbBiological sex is also an inherited variation - whether you are male or female is a result of genes you inherited from your parents. Environmental causes of variation …
Webb19 juli 2024 · The environmental variation is mostly found in plants. The environmental variation is caused by the external environmental factors such as light, temperature, moisture, minerals, and the exposure to various other factors. Biological factors such as parasites may also cause environmental variation. WebbDiscontinuous variation is the variation seen among individuals when each individual shows one of two—or a very few—easily distinguishable traits, such as violet or white flowers. Mendel’s choice of these kinds of traits allowed him to see experimentally that the traits were not blended in the offspring as would have been expected at the time, but …
Webb16 juli 2024 · Mutation, gene flow, sexual reproduction, random mating between organisms, random fertilization, and crossing over are the main cause of genetic variation. Genetic variation along with environmental variation causes phenotypic variation in a population. An example of phenotypic variation is the height of a plant. Main source or cause of …
