A purple flower (PP) is is crossed with a white flower (pp). Which combination of alleles is the only possible outcome?
*** = My answer
A) Pp***
B) PP
C) pp
NVM. That was the correct answer. I took a chance to answer it by myself.
Thank you for trying @ WriteTeacher
Is this correct? Anybody? @Ms. Sue ? @WriteTeacher ?
No idea! I haven't studied biology or botany since before I earned my BA!!
To determine the possible outcomes of a cross between a purple flower (PP) and a white flower (pp), we need to understand the principles of Mendelian genetics and the concept of alleles.
Alleles are different forms of a gene that occupy the same position on a pair of homologous chromosomes. In this case, there are two alleles for the flower color gene - P (representing the purple color) and p (representing the white color).
When two parents with different alleles for a specific trait reproduce, each contributes one allele to their offspring. The possible combinations of alleles depend on the genotypes of the parents.
The genotype of the purple flower (PP) indicates that both alleles are the same (homozygous) and dominant (P). The genotype of the white flower (pp) indicates that both alleles are the same (homozygous) and recessive (p).
During the process of sexual reproduction, the offspring receive one allele from each parent. In this case, the only possible outcome is that the offspring will inherit one purple allele (P) from the purple flower and one white allele (p) from the white flower.
Therefore, the correct answer is:
A) Pp
