Question

(3 of 15) Assume that 'X' and'Z' are alleles, different versions of genes that encode proteins the corn borers make in their gut. The picture shows a representative sample of the members of the current corn borer population. Corn borers that are XX and XZ have the best digestive system for eating corn plant tissues and reach adulthood more rapidly and in better health than corn borers that are ZZ. Given the description in the paragraph above when the population of corn bores is eating corn. Assume the picture above shows a population of ECB are x -- are XZ and * * * * * * * * * * are ZZ allele X should be more common in the gene pool next year than this year. Oallele Xshould be less common in the gene pool next year. Oallele Xhas no impact on corn borer fitness.

Explanation / Answer

4Q). b. the following kinds of gametes: AB, Ab, aB, and ab.

Cross between Aa and Bb will have the offspring with the following genotypes,

Aa*Bb ---------> AB (1/4), Ab (1/4), aB (1/4), ab (1/4).
