The frequency of recessive yellow beans resulting from a cross between two heterozygous plants is 25%.

<h3>What are recessive alleles?</h3>

Recessive alleles differ from dominant alleles in not being able to express themselves in heterozygotes. These alleles are only expressed in the phenotype if they are present in pairs, that is, they must be in homozygosity.

With this information, we can conclude that the frequency of recessive yellow beans resulting from a cross between two heterozygous plants is 25%.

mixer [17]

Answer:

20 percent

Explanation:

Dystrophia myotonica protein kinase gene, DMPK is a kind of autosomal dominant mutation. Since this disease is autosomal, it is not affected by the sex chromosome. Out of total 23 chromosome pairs in human being, 22 are autosomal chromosome while one pair is sex chromosome. Also autosomal dominant means that the mutated gene is a dominant gene that is found in the non sex chromosomes.

Thus, only one mutated allele is required to pass on the mutation through the families hierarchy.

Thus, the mutation rate of the DMPK gene is

\frac{3}{15} * 100\\= \frac{1}{5} * 100\\= 20%
