ANSWER

genes ; alleles

EXPLANATION;

DNA is the genetic material, which is broken into chromosomes. In humans there are 46 chromosomes( 23 pairs) , out of which 22 are homologus , these are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during fertilization. The remaining is 1 pair is sex chromosome(X , Y _not homologous because their size and gene content differs.)

22 pairs of homologous chromosomes (results from mitosis and genetic recombination during meosis)are very similar to one another.As they:

  • Have the same size and shape.
  • Carry the same type of genetic information.
  • Have the same genes in the same locationslocations, chrosome length and centromere location.

But they potentially differ because, they code for different traits in their allelic forms since one was inherited from the maternal side and one from the paternal side.

It is because of these similarity and difference, a species pass down same genetic information, while each individual is distinct with varying phenotypic characteristics.

To simulate Prophase of Meiosis I - Synapsis and Crossing Over: 1. Homologous chromosomes come together and synapse along their entire length. This pairing (synapsis) of homologous chromosomes represents the first big difference between mitosis and meiosis. This pairing will produce two tetrads, each consisting of four chromatids. Entwine the two chromosomes to simulate synapsis. 2. To simulate crossing over, start with your long tetrad and transfer the circles on the red chromatid at the fourth bead or “gene” to...
