Why would it be important to know the possible genotypic and phenotypic ratios of different genetic crosses?
OleMash [197]
It’s important to know the possible genotypic and phenotypic ratios of different genetic crosses because the the phenotype shows what the offspring will physically look like what the genotype is what genes the offspring carries. phenotype doesn’t always show what alleles the offspring carries because if the offspring is heterozygous for the gene only the dominant allele shows and the recessive allele won’t be visible. the genotype can see what alleles the offspring carries, both dominant and recessive. knowing the genotype helps to know what alleles are passed on. if one of the parents have a genetic mutation that is passed on, the phenotype helps see what ration of offsprings will have the mutation visible and the genotype will help see what ratio of offsprings will pass on the allele for the mutation
