What is genotypic and phenotypic ratio of monohybrid cross |
|
Answer» The EXPECTED genotype RATIO when two heterozygotes are crossed is 1 (homozygous dominant) : 2 (heterozygous) : 1 (homozygous recessive). When a phenotypic ratio of 2 : 1 is observed, there is probably a LETHAL allele. ... The heterozygotes have a phenotype DISTINCT from normal cats. |
