An allele pertains to one of the 2 types of a particular gene. While a gene can have numerous alleles, a lot of plants do come with just two alleles, from the male and female parents. Therefore, two alleles that originated from one gene pool may produce tall and short plants or one plant with flowers in different colors.
“I notice strange things in my cannabis garden lately. I have a particular plant inside with beautiful flowers that are in different shades of colors. My friends said it’s because of an allele.”
“I found allele something magically in plants. My plants differ in their size, which I don’t find a big deal.”
