can you cross two plants with light red flowers and get Offspring with white flowers? explain. (Light Red genotype is AABb, AaBB)
Assuming the small letters stand for recessive genes for white, then no. They will always be paired with dominant genes for color (expressed in capitals).

Yes, it is possible to cross two plants with light red flowers and obtain offspring with white flowers. To understand how, we need to consider the genetics behind flower color inheritance.
In this case, the genotype of the plants with light red flowers is AABb (one dominant allele A and one recessive allele b) for one parent and AaBB (one dominant allele A and one recessive allele b) for the other parent.
To determine the potential flower color of the offspring, we need to consider the principles of dominant and recessive alleles. In this scenario, the dominant allele A produces light red flower color, while the recessive allele b produces white flower color.
Now, when these two plants are crossed, the possible combinations of alleles that the offspring can have are:
- AA: Since both parents have at least one dominant allele A, there is a possibility of producing offspring with light red flower color.
- Aa: As one parent has the genotype AABb and the other parent has AaBB, there is a possibility of producing offspring with light red flower color.
- BB: As both parents have at least one dominant allele B, there is a possibility of producing offspring with light red flower color.
- bb: For the offspring to have white flower color, they must inherit the recessive allele b from both parents.
Therefore, there is a chance of obtaining offspring with white flowers if each parent passes on their recessive allele b to their offspring.
In summary, to obtain offspring with white flowers from two plants with light red flowers, it is necessary for both parents to carry the recessive allele b.
