Asexual vs Sexual reproduction - getting a better understanding of homologous chromosomes

Some more review on Haploid Vs Diploid Cells during the Daily Questions - As well as a little better look at what zygotes are and the concept of how homologous chromosomes get separated during Meiosis.
Not here today???  Here is a clip of our discussion about Homologous Chromosomes:



We finished up Advantages / Disadvantages to Asexual Reproduction:

An advantage of asexual reproduction to GREMLINS is shown in this clip...... ;)


It may be an advantage to THEM.... but a disadvantage to US!!!!
Then on to Sexual Reproduction


Then worked with the chromosome models again - Seeing the relationship between Homologous Chromosomes:
Using the models we noted what a diploid cell was.  Diploid means there are TWO of every chromosome (one from mom and one from dad).  Pairs of chromosomes are known as homologous chromosomes.
