In the study of Gigord and colleagues using Elderflower orchids, the allele frequencies of yellow and purple flowers varied such that when the yellow allele started to become rare, the reproductive success of purple flowers decreased and the reproductive success of yellow-flowered individuals increased in a process known as <u>frequency-dependent selection.</u>

<u></u>

Frequency-dependent selection is an evolutionary process in which the fitness of a phenotype or genotype is dependent on the frequency of that phenotype or genotype in a particular population.

  • Positive frequency-dependent selection raises the fitness of a phenotype or genotype as it becomes more prevalent.
  • In the case of negative frequency-dependent selection, the fitness of an increasingly prevalent phenotype or genotype diminishes.

In a broader sense, frequency-dependent selection involves biological interactions that make the fitness of an individual dependent on the frequencies of other genotypes or phenotypes within the population.

In terms of ecosystem stability and predator-prey interactions, what is the concern over declining krill populations
yKpoI14uk [10]

Declining krill populations will have catastrophic consequences for ecosystem homeostasis and it will increase the levels of phytoplankton.

<h3>What is ecosystem homeostasis?</h3>

The term ecosystem homeostasis makes reference to the state of equilibrium between different species in an ecosystem.

Krill are fundamental primary consumers in aquatic environments and they eat autotrophic phytoplankton.

In conclusion, declining krill populations will have catastrophic consequences for ecosystem homeostasis and it will increase the levels of phytoplankton.

12. A plant has a dominant phenotype but an unknown genotype. The proper experiment to determine its correct genotype would be a
jekas [21]

Answer:

the correct answers are as follows

12:

b. Testcross- an organism with dominant phenotype but unknown genotype is crossed with homozygous recessive organism for the same trait. Based on the results obtained, if all offsprings have the same phenotype, then the parent is homozygous, but when a 1:1 ratio is observed in the offsprings, then the parent is heterozygous.

13.

e. Watson and Crick- they both used the crystallographic images from Franklin, analyzed them to first elucidate the 3D structure of the DNA and propose it to the world.

14.

c. Intracellular and commonly found in the cytoplasm- the receptors of steroid hormones are generally present within the target cell either in the cytoplasm or nucleus, since they alter gene expression.

15

e. Certain prokaryotes/bacteria- this is a process that will enable disease-causing pathogens to communicate and cooperate with their group, by the release of autoinducers that increase their cell density.
