In the aster Leucelene roseata petal color may be lavender p

In the aster, Leucelene roseata, petal color may be lavender, pink or white. Color is due to three alleles: c^r; c^p; c^w. Regardless of what crosses you make between petal color phenotypes, you never obtain male progeny with pink petals. What could be true? (you may choose more than one answer)

-Pink is recessive in males

-Pink is codominant, males ar heterogametic

-Expression of pink is limited ot females

-Pink is a lethal recessive on the X-chromosome

-The described results are impossible

Solution

Answer: Pink is recessive in males and Expression of pink is limited ot females

Pink may be recessive trait, which is dominated by other dominant trait. Dominant trait preventing the formation of the pink colour.

The expression of pink trait in female is known from given information and pink is specific for only female and not observed in males. Pink gene can be X-linked gene, so it is not observed in female.
