In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
Dvinal [7]

Answer:

Phenotype genotype Number of individuals

Red RR 245

Pink Rr 210

White rr 45

Number of alleles in total

R = 245 + 245 + 210 = 700 ---> 700/1000= 0.7 R frequency

r = 210 + 45 + 45 = 300 -----> 300/1000 = 0.3 r frequency

Predict (Hardy Weinberg) genotype frequencies=

p^2 + 2pq + q^2 = 1

p= 0.7

q=0.3

0.49 + 0.42 + 0.9 =1

According Punnett Squares in F1 we have=

Rr* rr = Rr 50% and rr 50%

Which of the following is an abiotic factor that limits the carrying capacity of animal species?
Nata [24]

Answer:

Should be D. Breathable gases

Explanation:

The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, and abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.

Need help with this evolution chart some I've filled in yet I'm not sure if they are correct.Plz help anybody
Svetllana [295]

Answer:

This is correct. The remaining portion:

Sympatric species that form interrelationships undergo coevolution.

Allopatric species in different environments can undergo convergent evolution.

Allopatric species in small populations and under intense environmental conditions can undergo genetic drift.

Explanation:

On the basis of geographical distance, speciation is of two major types:

  1. Sympatric
  2. Allopatric

Sympatric Speciation:

Sympatric speciation is the formation of new species with no gergraphical separation from the ancestor. The new and parent species both exist in the same environment but do not interbreed due to mechanisms of reproductive isolation. These involves both prezygotic and post zygotic barriers to reproduction such as timing of mating, sensitivity to pheromones, choice of mating sites or infertility and mismatched gametes. Species formed through sympatric speciation can form interrelationships and undergo coevolution i.e. the evolution of ones species is dependent on the other.  

Allopatric Speciation:

It involves the geographical separation of the parent and new species. These species could be geographically separated by a river, mountain range or land mass.

Although, allopatric species evolve independently, they may develop similar characteristics that serve different functions. Allopatric species in radically different environments undergo convergent evolution i.e. species evolve similar characteristics without any ancestral homology.

Allopatric species that reside in small populations and are under harsh environmental pressures undergo a rapid genetic revolution i.e. genetic drift. This includes the Founder's and bottleneck effect that involve the continuation of a species from very few individuals after a drastic, sudden environmental change.
