Does anyone know what the phenotype ratio is for all three of these are? 2) which genotype and phenotype for fur lengths are recessive? 3) if you have a hamster with short fur, what possible genotypes could the hamster have? 4) which hamster's are the parent's of the mystery hamster? include evidence to prove that they are the correct parents.

2) The recessive genotype is ff; and the phenotype is short fur.

3) If you have a short fur hamster, the possible genotype is ff.

Phenotype Ratio of Punnett Square 1

short fur- 0; long fur- 4 so your ratio is 0:4

Phenotype Ratio of Punnett Square 2

short fur- 1; long fur- 3 so your ratio is 1:3

Phenotype Ratio of Punnett Square 3

short fur- 4; long fur- 0 so your ratio is 4:0

hopefully this helps and if you need any more help just ask me :)

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
