The various chromosomal mutations and their effects. Introduction: Each chromosome contains a single DNA molecule. All these chromosomes must be compacted in order to fit the nucleus of the cell. All eukaryotic organisms contain chromosomes, and the number of chromosomes varies in different organisms. In humans and several other species, diploid (2n) number of chromosomes is present. Therefore, for humans, the diploid and haploid numbers are 46 and 23, respectively. The diploid number of chromosomes indicates that each parent contributes equally to the offspring. The variant forms of a particular gene located at the same genetic locus or position on a chromosome are regarded as alleles.

In a population of Jackalopes (pictured below), horn length will vary between 0.5 and 2 feet, with the mean length somewhere around 1.05 feet. You pick Jackalopes that have horn lengths around 1.75 feet to breed as this appears to be the optimal length for battling other Jackalopes for food. After a round of breeding, you measure the offsprings' mean horn length is 1.67. What is the heritability of horns length (h2)? Is Jackalope horn length a heritable trait?

There are many differences between DNA replication happening during mitosis in a Douglas fir tree growing in the Oregon Cascade Mountains and DNA replication happening during a PCR reaction in a forestry research lab at Oregon State University where the laboratory is amplifying a Simple Sequence Repeat. Complete the following table that compares the two DNA replication events in terms of the primers, the nucleotides, the polymerase, and the target sequence. Additionally, give a general value for the number of copies of the template DNA after one S phase in one cell and after the lab has completed the PCR reaction.
