Solution

To answer the question, we need to understand the terms mentioned and their relationship to each other.

  1. Gametes: Gametes are reproductive cells, such as sperm and egg cells, that contain half the number of chromosomes compared to other cells in the body. They are involved in sexual reproduction and combine during fertilization to form a zygote.

  2. Zygotes: Zygotes are formed when two gametes, one from each parent, combine during fertilization. They contain a complete set of chromosomes, with one set from each parent. Zygotes develop into embryos and eventually into organisms.

  3. Chromatids: Chromatids are duplicated copies of a chromosome that are joined together by a structure called a centromere. They are formed during the DNA replication phase of the cell cycle and are separated during cell division.

  4. Alleles: Alleles are different forms or variations of a gene. They occupy the same position, or locus, on homologous chromosomes. For example, there can be different alleles for eye color, such as blue or brown.

Based on the given information, the correct answer is (4) alleles. Two genes located in corresponding positions on a pair of homologous chromosomes and associated with the same characteristic are known as alleles.
