Answer:
Cow 1 Genotype: RR
Phenotype: red and white
Genotypic: 4 RR
Phenotypic:4RP
Cow 2 Genotype: RW
Phenotype: red and white
Genotypic: RW
Phenotypic: 4 RW
Cow 3 Genotype: RW RR
Phenotype: red,red white
Genotypic: 2 RR ,2 RW
Phenotypic: 2, RW,2 RR
Q5. Yes, we can trace the father of the calves. Cow
1 will have red calves; Cow 2 will have roan calves;
Cow 3 will have red and roan calves.
Q6. Yes. I'm going to explain that the result are
different because of how genetic works. In the Cow
2 and 3's results, we can see that it is an example of
Codominance because the two alleles (RR, RW) of
the parents are both fully expressed (R for red, W for
white).
Q7. We can use the lesson we learned about
genetics (Codominance).
Q8. Animal breeders can cross breed animals in
able to get the desired traits that can improve their
livestock in terms of the quality of meat and milk
production.
