A locus determines the type of pigment produced in the squash, with yellow (Y_) dominant over green (yy). This locus is expressed only in ww plants, which lack the dominant inhibitory allele W. We can assign the genotype ww Y_ to plants that produce yellow squash and the genotype ww yy to plants that produce green squash. The genotypes and their associated phenotypes are:

The stages in the formation of the symbiotic relationship between the nitrogen-fixing bacteria and their host, Arrange the given statements of symbiotic association in a stepwise manner;
a) Migration of the bacteria toward the roots of the host plant by a chemotactic response mediated by chemical attractants
b) NodD with the flavonoids bind with the Promoter region of highly conserved the nod box
c) These attractants activate the rhizobial NodD protein,
d) The chemical attractants especially (iso)flavonoids and betaines, secreted by the roots
e)
Binding of the activated NodD to the nod box induces transcription of the other
nod genes
