In the pearl-millet plant, color is determined by three alleles at a single locus: Rp1 (red), Rp2 (purple), and rp (green). Red is dominant over purple and green, and purple is dominant over green (Rp1 > Rp2 > rp). What will be expected phenotypes and ratios of offspring produced by the Rp1/rp × Rp2/rp crosses?

Hormonal interactions contribute to plant–insect herbivore interactions such as— ethylene, salicylic acid, and jasmonic acid. In particular, ethylene appears to play an important role in this context, what will be the effect of ethylene when is applied alone and when is applied with other amino acids?

a) ethylene applied together with JA it seems to reduces defense responses

b) Ethylene appears to applied alone to plants, ethylene has little effect on defense-related gene activation

c) when ethylene applied together with JA it seems to enhance JA responses or defense responses are significantly increased

d) Ethylene appears to applied alone to plants, ethylene has more effect on defense-related gene activation

Which of the following combination is correct about ethylene effects?
