Which of the following is true about a plant with the genotype AABbcc?A. It is heterozygous at two loci.

b. It is homozygous at two loci. It is triploid.

c. It will not express the recessive c allele.

d. It has recessive alleles at three loci.


The given question is incorrect. The correct question is:

Which of the following is true about a plant with the genotype AABbcc?

a. It is heterozygous at two loci.

b. It is homozygous at two loci.

c. It is triploid.

d. It will not express the recessive c allele.

e. It has recessive alleles at three loci.

Answer:

b. It is homozygous at two loci.

Explanation:

When an organism has two identical alleles of a particular gene, it is said to be homozygous for that gene. The given genotype "AABbcc" has a dominant allele for "A" and the recessive allele for "c". It is homozygous for these two genes but is heterozygous with respect to "B". The presence of three complete sets of chromosomes makes the organisms triploid. The given genotype carries two alleles for each gene and therefore, it is diploid.
