Understanding Gametes
* Gametes are reproductive cells (sperm or egg) that carry one copy of each chromosome.
* Genotype refers to the genetic makeup of an individual.
The Rule of Two
For each heterozygous gene (where the alleles are different), there are two possible gametes.
* Aa can produce gametes with either "A" or "a"
* Bb can produce gametes with either "B" or "b"
* cc is homozygous, so it only produces gametes with "c"
Calculating the Number of Gametes
1. Identify the heterozygous genes: In this case, Aa and Bb.
2. Apply the rule of two: Since there are two heterozygous genes, there are 2 x 2 = 4 possible combinations.
Therefore, an individual with genotype AaBbcc can form 4 different gametes.
