Explain how the alleles were passed from parents to offspring.

lleles are different versions of a gene that determine specific traits in an organism. Each individual inherits two alleles for each gene, one from each parent. The process of passing alleles from parents to offspring is called inheritance.<br /><br />In sexual reproduction, each parent contributes half of their genetic material to their offspring. This genetic material is contained in the form of gametes, which are sperm cells in males and egg cells in females. Each gamete contains only one allele for each gene.<br /><br />When a sperm cell fertilizes an egg cell, the resulting zygote contains two alleles for each gene, one from each parent. These alleles may be the same (homozygous) or different (heterozygous). If the alleles are different, one may be dominant and the other recessive. The dominant allele will determine the trait, while the recessive allele will be masked.<br /><br />For example, let's say a parent has the alleles A and a for a particular gene. The A allele is dominant, and the a allele is recessive. If the other parent has the alleles B and b for the same gene, where B is dominant and b is recessive, their offspring could inherit any combination of these alleles. The possible combinations are AB, Ab, aB, or ab.<br /><br />In summary, alleles are passed from parents to offspring through the process of inheritance, where each parent contributes half of their genetic material to their offspring. The resulting combination of alleles determines the traits of the offspring.
