Answer:
Fraternal twins are “dizygotic,” meaning that they developed from two different eggs fertilized by two different sperm cells, while identical twins are “monozygotic” i.e., they developed from a single fertilized egg that split.
Explanation:
The main reason that most farmers use stem cuttings rather than just planting a seed is that a tree's genetic variation will occur. The seeds of many fruit trees tend to vary differently from the parent, because seeds themselves are produced by sexual reproduction (i.e they receive genes from a male and female to form). As they are a cross from two sets of genes, many fruit trees are not “true to seed”. Their seeds will produce a generally different variety of tree from the parent. When using stem cuttings, it's almost like a cloning process.
C, you have genes/allels that you got from your parents, but the combination of all your genes together is unique.
Competitive inhibition can be overcome by increasing the concentration of substrate while uncompetitive and noncompetitive inhibition cannot. Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity.
