Random Fusion of Gametes Someone out there Two mating individuals have the same kinds and same number of chromosomes, but those chromosomes are not exactly identical. Because individuals possess different variations of genes, the random fusion of gametes (fertilization) from any two individuals will result in more genetic variety in the offspring. Through fertilization the diploid set number is recreated with the offspring receiving one chromosome of a homologous pair from one parent, and the other chromosome of the pair from the other parent. is more genetically like you than either of your parents. ? QUESTION To keep the example relatively simple, let's consider only one of the homologous pairs of the human-the A chromosome. (Actually, human chromosomes are referred to by numbers from 1 to 23.) Al came from 1. Where did chromosome A2 come from? A' A2 your father 2. Where did chromosome A4 come from? 3. What are your possible gametes? You What are your mate's possible gametes? 4. Determine the four possible combinations of your gametes with your mate's gametes. In other words, what genetic variety can we expect in your offspring? 5. A3 came from A3 your mate's father A4 Your Mate
