Question

In humans blood type is determined by the A, B, and O alleles, The A and B alleles are codominant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes?
1.) A, B, or O only
2.) A or B only
3.) A, B, AB, or O
4.) O only
PLEASE HELPPP!!!

Answer 1

Alleles are defined as the alternative forms of gene, which are found on the same loci on a chromosome. The individual with AO and BO genotype will produce offspring with genotype:

3.) A, B, AB, or O

Alleles are the two or more genes that are present on the same locus of chromosome. In the given question, it is given that:

• A and B are codominant genes.
• O is a dominant gene, which can be masked by A and B alleles.

The genotype of the offspring can be A, B, AB, or O. It is due to the co-dominance of alleles. Co-dominance is defined as the relationship between two variants of the gene. In co-dominance, both the alleles are expressed and observed in the phenotype. Thus, the offspring can have any of the blood types.

Therefore, the offspring can posses A, B, AB, or O blood group due to co-dominance of alleles.

Answer 2

An Individual with AO genotype and an Individual with BO genotype will produce an offspring with ; ( 3 ) A, B, AB, or O

Given that the alleles A and B are codominant to each other and dominant to allele O, this means that alleles A and B can be seen and expressed in a phenotype while allele O is also dominant but becomes recessive when paired with either A or B.   while  

Phenotype with allele O is seen and expressed when not paired with any dominant allele. therefore Individuals with AO genotype and BO genotype will produce offsprings with  A, B, AB, or O  blood groups due the codominance factor possessed by alleles A and B.

Hence we can conclude that An Individual with AO genotype and an Individual with BO genotype will produce an offspring with ; ( 3 ) A, B, AB, or O
