Answer 1

Answer:

11. answer (a).

explanation:- gene gives the product by synthesizing the polypeptides which are a chain of amino acids

12. answer (b).

Genes are always organised in linear fashion

13. answer (a)

explanation:- mono: one. one trait crossing is referred as monohybrid

14. answer (c)

explanation:- as per mendalian dihybrid genotypic ratio, it is 9:3:3:1.

15. answer (c)

explanation:- homo means same, zygous means specific state

16. answer (b)

explanation:- hetero means different; zygous means specific state.
