Assume that three loci, each with two alleles (A and a, B and b, C and c), determine the differences in height between two homozygous strains of a plant. These genes are additive and equal in their effects on plant height. One strain (aabbcc) is 10 cm in height. The other strain (AABBCC) is 22 cm in height. The two strains are crossed, and the resulting F1 are interbred to produce 1000 F2 progeny. what is number of F2 progeny having intermediate height?

Following are certain strategies used by pathogen to attack over the host plant that describe plant-pathogen interactions:
I II
A. Necrotrophic pathogens i) most of the plant tissue remains alive and only minimal cell damage can be observed, as the pathogens feed on substrates provided by their host
B. Biotrophic pathogens ii) In which the host cells are kept alive as described for biotrophic Pathogens and followed by a necrotrophic stage, in which the pathogens can cause extensive tissue damage
C. Hemibiotrophic pathogens iii) attack their host by secreting cell wall–degrading enzymes or toxins, which eventually kill the affected plant cells, leading to extensive tissue maceration. This dead tissue is then colonized by the pathogens and serves as a food source
Which of the following above combination is correct?
