Meiosis (1 of 3): Genes, Chromosomes, and Sexual Reproduction (BioFlix tutorial)


Meiosis ensures the transmission of traits from one generation to the next. At the same time, it is a key process that introduces genetic variation into the traits that offspring inherit from their parents. In this tutorial, you will explore the genetic context of meiosis.
Before beginning the tutorial, watch the Meiosis animation. You can review relevant parts of the animation at any point in the tutorial.


Part A - Meiosis terminology
Drag the labels from the left to their correct locations in the concept map on the right.

Part B - Interactions among chromosomes
This diagram shows a diploid nucleus (2n=8) in which chromosome replication has occurred in preparation for mitosis (top) and meiosis (bottom). The nucleus at top right is now in prophase of mitosis; the nucleus at bottom right is now in prophase I of meiosis.
Drag the labels to their appropriate targets to correctly identify the various chromosome structures. Labels can be used more than once.

Part C - Animal life cycles
In 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.

Correct
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. Provide FeedbackContinueCor rect. Followup. 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. End of followup.
