P(purple) and p (white) are the dominant and recessive alleles for flower color in peas. similarly, a (axial) and a (terminal) are the dominant and recessive alleles for flower position in peas. two plants with the genotype ppaa are crossed. which genotype is indicative of white axial flowers?

ppAa or ppAA is the genotype that’s indicative of white axial flowers. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

The genotypes that are indicative of white axial flowers are-

Explanation-    

As per the information in the question, purple color ( depicted by 'P' allele) is dominant over white color ( depicted by 'p' allele) and axial ( 'A' allele ) is dominant over terminal position ( 'a' allele) for flower in peas.

Dominant trait is the one that masks the expression of the recessive trait. As white is a recessive trait ( only produced with genotype 'pp') and axial ( genotype 'Aa' and 'AA') is a dominant trait , so there can be two possible genotypes for white axial flowers that are ppAa and ppAA.

Therefore, when plants with genotype PpAa are crossed, the genotypes  ppAa and ppAA in the offspring will give white axial trait.

Refer punnett square.

i am going to guess that it is co2.

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.
