Answer
Q1
a) chromosomes from same gene but from 2 parents.
They are chromosomes of similar length, loci and staining pattern but one from father and one from mother.
Q2
Variations of DNA sequence in allele of a gene.
Allele is gene. Eg - 2 different allele of same gene in heterozygous.

Assortment of genes on same chromosome In the fruit fly Drosophila, there is a dominant gene for normal wings and its recessive allele for vestigial wings. At another gene locus. there is a dominant gene for red eyes and its recessive allele for purple eyes. A female that was heterozygous at both gene loci was mated with a male that is homozygous for both recessive alleles. Knowing this, complete the sentences with the correct terms. 94% crossing over independent assortment...

9. Different genes are located on different kinds of genetic elements - autosomes, W chromosomes, the mitochondrial genome, etc. Different elements are inherited in different ways, so different offspring inherit different elements from different parents. For each case, answer "both parents', 'mother', 'father, or 'neither parents. For instance, sons inherit autosomal genes from both parents, but sons inherit W chromosome genes from neither parent (because males are ZZ, and don't have a W chromosome...) (1 point per answer) Sons inherit...

What genes (or kind of genes) will you focus on in your investigative research? Provide 2-3 reasons for your choice of these gene/s. Starting with the bone sample itself, what methods will you use to get DNA that you can sequence? Which “ingredients” in your lab reactions will determine which gene or genes are copied? How is it that these ingredients are able to target a specific gene? What method will you use to see if your efforts to copy...
