If the principle of segregation was incorrect, what would Mendel's cross of two heterozygous individuals (for seed shape) yield?
DiKsa [7]

Answer:

The options are missing, the options are:

(a) the ratio of round to wrinkled would have been unpredictable and change each generation

(b) all of the seeds would have displayed the dominant trait, round

(c) it would have yielded the same results as he originally saw

(d) an inversed 3:1 ratio, wrinkled:round

(e) no offspring would have been produced, so there would be no ratio

The correct answer is A

Explanation:

Mendel proposed that alleles of a gene separates into gametes during gamete formation. He called this Law of Segregation. He also stated that in an heterozygous organism, each different allele separates into gamete will equal frequency. He was able to predict the phenotypic ratio of 3:1 for the F2 generation using this principle and it proved right.

If his principle of segregation were false, it would have been impossible to predict the phenotypic outcome of the offsprings i.e. in what proportion each trait will occur. This unpredictability would have changed the ratio of the offsprings in each generation. For example, in the case of seed shape gene, if the round and wrinked alleles didn't separate in equal frequencies, it would be impossible to come up with a prediction of 3:1 ratio of round to wrinked seeds.
