Question

In an investigation,Snapdragon plants with broad leaves (B) were crossed with plants with narrow leaves (N).The F1 progeny had intermediate leaf breadth

Give a reason for intermediate leaf breadth in F1 generation

Answer 1

[AI-generated answer — Bot GPT 3.5]

The intermediate leaf breadth in the F1 generation could be due to incomplete dominance of the genes responsible for leaf breadth. In incomplete dominance, neither allele is completely dominant over the other, resulting in a blending of the two traits. In this case, the broad leaf allele and narrow leaf allele are both at play, causing the F1 progeny to have an intermediate leaf breadth.
