PART C – Animal life cyclesIn the life cycle of an organism, meiosis is paired with the process of fertilization. Understanding the life cycle of an organism is the key to understanding how sexual reproduction ensures the inheritance of traits from both parents and also introduces genetic variation.Complete the diagram to show the life cycle of a typical animal.Follow these steps:1. First, drag blue labels onto blue targets only to identify each stage of the life cycle.2. Next, drag pink labels onto pink targets only to identify the process by which each stage occurs.3. Then, drag white labels onto white targets only to identify the ploidy level at each stage.Labels can be used once, more than once, or not at all.
[Meiosis creates gametes (eggs and sperm) with only a single chromosome set (haploid or n) from parental cells with two chromosome sets (diploid or 2n). During fertilization, the haploid sperm (n) and egg (n) fuse, producing a diploid zygote (2n). The cells of the zygote then divide by mitosis (which does not change the ploidy level) to produce an adult organism (still 2n) of the next generation.In sexual life cycles, meiosis and fertilization keep the number of chromosomes constant from generation to generation.]
As an AI language model, I don’t have access to the interactive diagram for this task. However, I can provide a detailed explanation of the life cycle of a typical animal.
The life cycle of a typical animal involves both haploid (1n) and diploid (2n) stages. The following are the different stages involved in an animal life cycle:
1. Gametes: Gametes are the haploid cells responsible for sexual reproduction. In animals, the female gamete is called the egg or ovum, while the male gamete is called the sperm. Gametes are produced by a specialized type of cell division called meiosis.
2. Fertilization: Fertilization occurs when a sperm cell fuses with an egg cell, forming a diploid zygote (2n). The process of fertilization results in the combination of genetic information from both parents, ensuring genetic variation in the offspring.
3. Embryo: The zygote divides by mitosis and forms an embryo. The embryo develops into a multicellular organism through a series of developmental stages.
4. Juvenile/adult: The juvenile/adult stage is the mature stage of the animal. The animal can reproduce and pass on its genetic information to its offspring.
Throughout the animal life cycle, meiosis and fertilization alternate to ensure genetic variation and the inheritance of traits from both parents.
