Can anyone answer these multi-choice biology questions?

a cross between two plants that have pink flowers produced plants that have red, pink, or white flowers. What is the most likely explanation for these results?





a. intermediate inheritance involved alleles that were not clearly dominant or recessive


b. mutations occurred during gametogenesis


c. crossing-over of whtie and red alleles occured during meiosis


d. nondisjunction of homologous pairs of chromosomes resulted in the production of abnormal offspring








2) the genes for red hair and freckles are usually inherited together because these genes are:





a. homologous


b. sorted independently


c. linked


d. hybrid traits








also.. what is the rule of independent assortment?

Can anyone answer these multi-choice biology questions?
A. In incomplete dominance red and white makes pink.





C. Linked genes are usually inherited together because they are on the same chromosome.





Independent assortment says that the way one pair of genes separates into the gametes does not affect the way another pair of genes separates. This really only works when genes are not linked: when they are not on the same chromosome.
Reply:1. A


2. C





Independent assortment means they are assorted independently.
