Post 7

We are experimenting with the kohlrabi plant or the scientific name Brassica oleracea.  I can't tell what parents our plant came from unless we do extent research.  We can predict what the offspring that our plant will be by looking at the genes of our plant and the plant that we would breed with it then find the dominant and recessive genes then create a punnet square.  These traits would be transferred to the offspring through the process of meiosis where the plant creates sex cells which has a mix of its genes in it and then transfer that to the female part of the plant. Meiosis is where one diploid creates a complete duplicate of itself then splits.  Then those two cells line up their chromosomes which cross-over then they are pulled apart creating unique daughter cells which are only haploid cells.  These cells are then transferred during sex or mating season between the two genders of plants.  The plants offspring will look like the parent but may not behave the same.  This happens due to the chromosomes and genes mixing providing different genes.  All the plants look different because they grew up in different places and had to adapt to survive along with the mixing of genes creating new species.  The variety has become so create because the genes have been mixing for so long there is tons of variation.
