Law of dual alleles
WebIn Mendelian inheritance, each parent contributes one of two possible alleles for a trait. If the genotypes of both parents in a genetic cross are known, Mendel's laws can be used to determine the distribution of phenotypes expected for the population of offspring. WebAlleles Can Be Dominant or Recessive Mendel’s law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same …
