## CORE INFORMATION\n✓ **Answer**: B\n## CONCEPT FRAMEWORK\n\t**Primary Concept**: Ploidy of a zygote\n\t**Related Topics**: Haploid, Diploid, Fertilization, Meiosis, Gametes\n\t**Prerequisites**: Basic understanding of cell division, gametes, and fertilization\n## SOLUTION PATHWAY\n**Given Information**:\n\t\tThe question asks about the ploidy of a zygote\n\t\tA zygote is formed from the fusion of two gametes.\n**Method & Steps**:\n\t1. **Understanding Gametes**: Gametes (sperm and egg) are haploid cells, meaning they have one set of chromosomes.\n\t\tReasoning: Haploid cells are produced by meiosis.\n\t\tFormula/Rule: N = Haploid, 2N = Diploid\n\t2. **Fertilization**: During fertilization, a haploid sperm cell fuses with a haploid egg cell.\n\t\tWorking: This fusion combines the genetic material of both gametes.\n\t\tKey Point: The combination of two haploid sets results in a diploid set.\n\t3. **Zygote Ploidy**: The resulting zygote has two sets of chromosomes, making it diploid.\n\t\tResult: Diploid (2N)\n\t\tVerification: This is a fundamental concept in sexual reproduction.\n ## OPTION ANALYSIS\n[A] :x: Haploid is the chromosome number in gametes, not a zygote.\n[B] ✓: Diploid is the correct ploidy for a zygote formed by the fusion of two haploid gametes.\n[C] :x: Triploid refers to three sets of chromosomes, which is an abnormal condition.\n[D] :x: Tetraploid refers to four sets of chromosomes, which is also an abnormal condition.\n ## LEARNING AIDS\n\t**Common Mistakes**:\n\t\t1. Confusing haploid and diploid: Remember that gametes are haploid and zygotes are diploid.\n\t\t2. Misunderstanding the process of fertilization: The fusion of two haploid cells always results in a diploid cell.\n\t**Quick Tips**:\n\t\t1. Think about the '2' in diploid. Two sets of chromosomes.\n\t\t2. Remember that 'zygote' is the result of fertilization, which is always diploid.

The correct Option is "Diploid"

## CORE INFORMATION\n✓ **Answer**: [Option D]\n## CONCEPT FRAMEWORK\n\t**Primary Concept**: Apomixis is a form of asexual reproduction in plants.\n\t**Related Topics**: Asexual reproduction, Sexual reproduction, Parthenogenesis.\n\t**Prerequisites**: Understanding of reproductive methods in plants and animals.\n## SOLUTION PATHWAY\n**Given Information**:\n\t\t- Apomixis is a type of reproduction.\n\t\t- It occurs without fertilization.\n**Method & Steps**:\n\t1. Identify the characteristics of apomixis.\n\t\tReasoning: Apomixis allows for the production of seeds without fertilization, leading to offspring that are genetically identical to the parent.\n\t\tFormula/Rule: Not applicable here as this is a biological concept.\n\t2. Compare apomixis with other reproductive methods.\n\t\tWorking: Apomixis is akin to asexual reproduction as it does not involve the fusion of gametes.\n\t\tKey Point: It produces clones, similar to how asexual reproduction works.\n\t3. Confirm the similarities with asexual reproduction.\n\t\tResult: Apomixis is fundamentally similar to asexual reproduction.\n\t\tVerification: Since apomixis does not involve sexual processes, it aligns closely with asexual reproduction.\n ## OPTION ANALYSIS\n[A] :x: Sexual reproduction involves gametes and fertilization, which is not the case in apomixis.\n[B] :x: Fertilization is the process of combining gametes, which does not occur in apomixis.\n[C] :x: Parthenogenesis is a form of asexual reproduction in animals but is different from apomixis in plants.\n[D] ✓: Asexual reproduction is the correct choice as both apomixis and asexual reproduction result in offspring that are genetically identical to the parent.\n ## LEARNING AIDS\n\t**Common Mistakes**:\n\t\t1. Confusing apomixis with sexual reproduction: Remember that apomixis does not involve fertilization.\n\t\t2. Misunderstanding the role of gametes: Apomixis produces seeds without gametes.\n\t**Quick Tips**:\n\t\t1. Associate apomixis with cloning: Both processes create genetically identical offspring.\n\t\t2. Recall that apomixis is specific to plants and relates to seed formation.
