Is it C?
To determine the possible outcomes of a genetic cross, we need to understand the concept of alleles and how they are inherited.
In this scenario, we have a green flower (GG) crossed with a white flower (gg). The green flower has two green allele copies, while the white flower has two white allele copies.
When organisms reproduce sexually, they inherit one allele for each trait from each parent. So, in this case, the offspring will inherit one allele for flower color from the green flower parent and one allele from the white flower parent.
According to the laws of genetics, when a dominant allele (G) is present, it always masks the expression of the recessive allele (g). In this case, green (G) is the dominant allele, and white (g) is the recessive allele.
Therefore, the possible combinations of alleles that could result from this cross are:
- GG (green)
- Gg (green)
- gg (white)
So, the correct answer is (c) Gg only, as it represents one possible outcome of the cross.
To determine the possible outcomes of genetic crosses, it is important to understand the principles of Mendelian inheritance and the concept of dominant and recessive alleles. By examining the alleles present in the parent organisms, you can predict which combinations are likely to occur in the offspring.
