View attachment 3456254 These are my two auto fem blueberry girls... Their the same age but why is one 17 inch tall and the other 5 inches ... I don't understand I did everything the same for both of them conditions are identical for both and regular light with 18/6 400 watt MH and around 80-85 during the day then 70-75 at night time
just a difference in phenotypic expression... aka "the way they look" caused by a lack of stabilization on your seeds. (breeders fault not yours)
in a population of plants that still show (in this case) high degrees of variation you can get big giant single cola monsters all the way down to little dwarf bushes.
height is polygenic so it takes many many generations of stabilization to get consistently uniform plants in regards to height.
Polygenic Traits and Environmental Influences
Another exception to Mendel’s rules is
polygenic inheritance, which is when a trait is controlled by more than one gene. Often these traits are in fact controlled by many genes on many chromosomes. Each dominant allele has an additive effect, so the resulting offspring can have a variety of genotypes, from no dominant alleles to several dominant alleles. In humans, some examples of polygenic traits are height and skin color. People are neither short nor tall, as was seen with the pea plants studied by Mendel, which has only one gene that encodes for height. Instead, people have a range of heights determined by many genes. Similarly, people have a wide range of skin colors. Polygenic inheritance often results in a bell shaped curve when you analyze the population . That means that most people are intermediate in the phenotype, such as average height, while very few people are at the extremes, such as very tall or very short.
