Choose the correct statement with regard to quantitative PCR?

#Unit 13. Methods in Biology
  1. End-point PCR is favourable over real time PCR
  2. In real time PCR, quantification is done as the reaction is going on
  3. If the product measurement is done after the completion then the measurement is done by target sequence and no other factor affects it
  4. If the primers are available in limited amount, then the product obtained is proportional to the target sequence

 Genes that control coat color in mammals represent some of the best early examples of genes with multiple alleles exhibiting different phenotypes. A classic example is the C gene in hamsters. Three of the known alleles of this gene are C, ca and ck. Each supplies a different amount of black pigment to the coat hair. The phenotypes of three different homozygous strains are as follows.

would mate the true-breeding  ca ca  hamsters to the true-breeding ck ck  hamsters to produce heterozygous  ca and ck  F1 progeny,  the F1 progeny cack  hamsters self fertilized, From the fraction of F2 progeny that have the wild type black phenotype, 

Crosses and their interpretation that would have allowed geneticists to come to the conclusion that ca and ck were likely to be alleles of the different gene.
