Two gene loci, A and B, assort independently, and alleles A and B are dominant over alleles a and b. Indicate the probability of producing an AB gamete from an AaBb individual.

Respuesta :

Two Gene loci, A and B

Explanation:

  • Step 1. The two quality loci, A and B, assort autonomously.
  • The alleles A and B are predominant over the alleles an and b. In this way, when a cross happens between AaBb X AaBb, the subsequent gametes would be AB, Ab, aB, and ab.
  • Step 2.The offsprings which have in any event one A and B allele, will show AB phenotype.
  • Along these lines, AABB, AaBb, AABb, AaBB, will all have AB phenotype.

If two gene loci, A and B, assort independently, the probability of producing an AB gamete from AaBb would be 1/4 or 25%

Since both A and B are independently inherited, Aa and Bb can be crossed just we would have it in a monohybrid cross following Mendelian pattern.

Thus:

                  Aa     x     Bb

                AB   Ab   aB   ab

The gametes and their respective probabilities of appearing would be:

  • AB - 1/4
  • Ab - 1/4
  • aB - 1/4
  • ab - 1/4

In other words, all 4 gametes have an equal chance of being produced during gametogenesis.
