Answer:
a. a strong hypersensitive response.
b. a high diversity of R proteins.
Explanation:
Hypersenstive response is an immediate defense system in plants because they don't have direct immune system. During an event of pathogen invasion, plant produces reactive radicals (reactive oxygen species, reactive nitrogen species, hydrogen peroxides) to kill the invading pathogen. Therefore, it should be included in the selection of tomato varities against novel biotrophic pathogen as a main criteria.
Further, R proteins are produced by R-genes (resistant genes) that is a defense line in plants against pathogens. Typically, it is known as a Pathogen-Associated Molecular Pattern or PAMP. The presence of r-genes in tomato varieties would help produce enzymes (r-proteins) that will kill or minimize the invador/infection. Hence, it should also be included as a main criterion for the selection of tomato varieties.
The question is incomplete and the complete question is
Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. A true-breeding female (aabb) with 6-cm ears is mated to a true-breeding male (AABB) with 16-cm ears.
Answer:
AABb or AaBB
Explanation:
We know that,
aabb genotype - 6 cm
AABB genotype- 16-cm
To calculate the length of earlobe contributed by each allele in a genotype is :
1. length of aabb/4 or 6/4= 1.5 cm (a and b contribute for 1.5 cm each)
2. Length of AABB/4 or 16/4= 4 cm (A and B contribute for 4 cm each)
Now to have the earlobe to be 13.5 cm long then the genotype must be
13.5 = 4+4+4+1.5 or A+A+B+b or A+a+B+B
Therefore, the genotype will be-either AABb or AaBB
