A variety of Pelargonium has yellow leaves. When plants of this variety are crossed, the resulting seeds produce green, yellow and white seedlings in the ratio 1 : 2 : 1. If plants with yellow leaves are crossed with plants with green leaves, what would the expected ratio of phenotypes in the offspring be?

Ratio of green is to white will b 1:1

Explanation:

Let 'G' be dominant green allele.

Let 'W' be recessive whiite allele.

Let a yellow plant will have 'GW' genotype

Crossing two yellow leaves plants will give one green, 2 yellow and 1 white leaves plants as shown in Punnet Square attached.

So we can conclude that

'G' is dominant green allele.

'W' is recessive whiite allele.

yellow plants have 'GW' genotype.

A cross between yellow leaf plant (GW allele) and green leaf plant (GG allele) will give two green leaf plant and 2 yellow leaf plant as shown in Punnet Square
