Answer:
36
Explanation:
A two-point test-cross is a cross between an individual with a double heterozygote genotype and a homo-zygous recessive individual in order to determine the recombination frequency between two linked genes. In genetics, one map unit (m.u.) can be defined as the measure of the distance (i.e., genetic distance instead of physical distance) between genes for which one (1) product of meiosis in one hundred (100) is recombinant. In this case, 36 of the offspring have the recombinant phenotype, while the remaining 64 offspring are not recombinant, and therefore both genes are separated by 36 mu (64 + 36 = 100 >> 36 mu).
Answer:
c. the cost to growth of allocating resources to defense
d. consistent fitness benefits of high allocations to defense
Explanation:
In order to ensure survival by escape of grazing and browsing by herbivores (and insects) plant usually adopt different defence mechanisms.This forms the basis for the optimum defence hypothesis .
The basic idea of the hypothesis is that the type of defence that an organism e.g plant will adopt against an herbivore depends on its fitness, and since this involve expenditure of energy it will be expensive for the organism to afford and maintain.
