Based on the ABC Hypothesis, correctly match each of the following genes, with the flower part they are switched on in. Switched on in the sepal and petal whorls Switched on in the petal and stamen whorls Switched on in the stamen and carpel whorls A. Gene C B. Gene A C. Gene B

Switched on in the sepal and petal whorls - Gene A

Switched on in the petal and stamen whorls- Gene B

Switched on in the stamen and carpel whorls - Gene C

Explanation:

The mechanism of flower morphogenesis in Arabidopsis has been deduced through a genetic model called ABC model. The floral homeotic gene  have been classified into 3 categories-A,B and C.

Genes from category A  -APETALA 1 and  APETALA2are expressed in petal and stamen primordia.

Genes from category B -  APETALA 3 and PISTILLATA  are expressed in petal and stamen primordia.

Genes of category C-  AGAMOUS affect stamen and carpels.

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.
