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 is indicative of white axial flowers.

ppaa is indicative of white axial flowers.

ppaa is indicative of white axial flowers.

Option C, ppAa is indicative of white axial flowers.

Explanation:

It is given that Purple color (P) is dominant over white color (p). Thus in order to have a flower of white color , the flower must be homozygous recessive with an allele pair having two recessive alleles.

Similarly, Axial (A) is dominant over terminal (a) flower. Thus, a flower can be axial in two cases -

a) when both the alleles are same i.e AA

or

b) when one allele is A and the other one is a i.e Aa

Considering the above cases, all possible allele combination that will produce white axial flower are as follows -

ppAA, ppAa

Thus, option C is correct

your answer should be c) enjoy!

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
