Why is the phenotypic ratio 2:1 the typical ratio for a lethal allele?
Lainey R.
In a mating between two individuals that are heterozygous for a recessive lethal allele that is expressed in utero, what genotypic ratio (homozygous dominant:heterozygous:homozygous recessive) would you expect to observe in the offspring? a. 1: 2: 1 b. 3: 1: 1 c. 1: 2: 0 d. 0: 2: 1
