For a monohybrid cross, you are crossing two alleles with two alleles. in a dihybrid cross, you are crossing four alleles with four alleles.
Yes because the plant's pollination would decrease
The Lock and Key Analogy of Enzymes and Substrates: Enzymes act as a catalyst in a given chemical reaction (for example, lactase allows lactose to break down into Glucose and Galactose); enzymes lower the amount of energy required to make a reaction occur. There is a key concept to this theory: Enzymes are designed work for only one reaction; there is only one key that fits the lock perfectly. Without enzymes, our bodies wouldn't be able to handle the amount of heat the reactions that occur inside if there weren't any enzymes (or the reactions just wouldn't occur! In the Lock and Key Analogy, the substrate (Lactose in the <span>example) is the "key".</span>
