If a white homozygous recessive flower is crossed with a red homozygous dominant flower, what will be the ratio of the phenotypes of the offspring? You may find it helpful to draw out the Punnett square. g

All red. The phenotypic ratio is 4/4 = 1, meaning 100% red flower.

Explanation:

Let the white flower be ww

Let the Red flower be RR

When recessive white flower, ww  is crossed with dominant red flower, RR , the offsprings that will be produced will be all Red. This is because the dominant character will overshadow the recessive character. This means that the red character will be seen outside while the white character will not be seen but present.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
