Brassica Rapa Fast Plant Traits
Experiment

Abstract:
How are traits passed down from one generation to the next? Does the genes from both parent combine into 1 or are the inherited by a whole where 1 is express while the other stays dormant. Using Mendel’s Laws as a base for our experiment, we will determine the expected outcome of these traits to help determine how genes are passed down. We will learn see if genes are randomly passed down and which genes of the parents are more likely to be expressed in the off springs. If the genes are passed down as a whole, then how can we tell which gene is the dominant and the recessive trait. How can reproducing an experiment similar to the pea pod plant can help us answer the question and support our hypothesis? In this experiment we will learn terms and definitions related to Mendel’s Law and comparing the actually experiment’s outcome compared to the data expected by Mendel’s Laws.

Introduction:
Genes are traits that give living things their own certain characteristic. Genes are inherited from the P generation to the F1 generation. As genes are passed down, they are given traits that are either contain all dominant genes known as homozygous dominant, or both dominant and recessive also known as heterozygous and last is homozygous recessive, meaning that the genes are both recessive. Dominant alleles are always present even if they also contain one recessive and the only way to express the recessive trait, both alleles must be recessive for the trait to be expressed. During sexual reproduction, 2 parents with different traits are crossbreed, which encourage cultural diversity out of the population. The offspring of the P1 generation is also call the hybrid since they have a mixed of traits from both parents. There are 2 type of crossbreeding first is...
