Answer & Solution
Correct Answer:
Option
B
An example of blending of alleles is paramutation in Maize.
A paramutation is an interaction between two alleles at a single locus, whereby one allele induces a heritable change in the other allele.
The first formal description of paramutation was given by R. A. Brink at the University of Wisconsin-Madison in the 1950s, who did his work in maize (Zea mays).
He noticed that specific weakly expressed alleles of the red1 (r1) locus in maize, which encodes a transcription factor that confers red pigment to corn kernels, can heritably change specific strongly expressed alleles to a weaker expression state.
