Is there a picture with this question? It seems like there's background information which isn't being shown here.
Pedigrees are basically a map of alleles for family trees
______Person1 -- Person2_____
I I I I
__Person3_ Person 4 Person5 _Person6___
I I I I I
Person7 Person8 Person9 Person10 Person11
And under everyone's name you write their alleles.
Punnett squares give the probability of someone having genes based on their parents' genes.

AA Aa aa aa
Answer:
a) During metaphase, each of the 46 chromosomes line up along the center of the cell at the metaphase plate.
<span>DNA replication is the production of identical DNA helices from a single double-stranded DNA molecule. Each molecule consists of a strand from the original molecule and a newly formed strand. Prior to replication, the DNA uncoils and strands separate. A replication fork is formed which serves as a template for replication. Primers bind to the DNA and DNA polymerases add new nucleotide sequences in the 5′ to 3′ direction. This addition is continuous in the leading strand and fragmented in the lagging strand. Once elongation of the DNA strands is complete, the strands are checked for errors, repairs are made and telomere sequences are added to the ends of the DNA.</span>
