If pink flowers are crossed with white flowers and all offspring are pink, which of these is most likely to be true? * Captionless Image
The white allele is dominant.
The pink allele is dominant.
White and pink alleles are codominant.
White genes were not passed on.

The answer is 25% red : 50% pink : 25% white

A - allele for red flowers

a - allele for white flowers

AA - flowers with red flowers

Aa - flowers with pink flowers

aa - flowers with white flowers

The cross looks like:

Parents:          Aa     x     Aa

Offspring:    AA    Aa   Aa    aa

Red flowers (AA): 1/4 = 0.25 = 25%

Pink flowers (Aa): 2/4 = 0.50 = 50%

White flowers (a): 1/4 = 0.25 = 25%

"the periodic table is arranged in order of atomic number."

the answer is 0.8m.
