5 True/False Questions
Polygenic traits → The scientific study of heredity
Does the environment have a role on how genes determine traits? → Environmental conditions can change the gene expression and influence genetically controlled traits.
Prophase I → Each chromosome pairs with its corresponding homologous chromosome to form a tetrad.
Crossing-over → process in which homologous chromosomes exchange portions of their chromatids during meiosis
Independent assortment → Pure bred means that the plants self-pollinate and produce offspring identical to themselves.
