Answer #1

Solution

The correct option is (C).

because according to ABC model of development of parts of flower is controlled by series of genes namely A,B and C.

A is responsible for sepal and petal development.

B is responsible for petal and stamen development.

C is responsible for stamen and carpel development.

  • A=sepal
  • A+B=petal
  • B+C=stamen
  • C= carpel

so option A is wrong beacuse it is simple process that can be describe.

option B ia wrong because it is not controlled by 3 genes (A,B,C) rather than one gene.

option D is wrong because it requires series of genes.

    can someome please help answer this? wo genes are required for cyanide production in clover. What are the functions of the gene products? Choose all that apply. One gene product catalyzed the production of a sugar-cyanide complex. One gene product catalyzes the release of cyanide from the sugar complex. Both gene products synthesize cyanide but are located in different parts of the cell. One gene product makes a sugar. One gene product makes cyanide from carbon and nitrogen
