In hamsters, there is a dominant allele (S) for smooth fur and a recessive allele (s) for spiky fur. A unique characteristic of

these alleles is that the heterozygote (Ss) has its own phenotype - rough fur. In this way, we can determind the number of heterozygotes in the population. In a population of 1000 hamsters, 390 have smooth fur (SS), 470 have rough fur (Ss) and 140 have spiky fur (ss).
What are the allele frequencies in this population?

Answer:

<em>What are the allele frequencies in this population?</em>

  • Frequency of S = 0.625  
  • Frequency of s = 0.375

<em>In the next generation of 1000 hamsters, what are the expected genotype frequencies?</em>

  • Frequency (SS) = 0.39          
  • Frequency (Ss) = 0.47          
  • Frequency (ss) = 0.14  

<em>What are the expected number of each genotype in the next 1000 hamsters?</em>

  • Individuals SS =  390
  • Individuals Ss =  469
  • Individuals ss =  140

<em>Have the allele frequencies changed?</em> No, they are the same

<em>Is the population in Hardy-Weinberg equilibrium?</em> Yes, it is.  

<em>The expected genotype frequency of Ss (2pq) in the next generation is expected to be: </em>0.469 (option a)

<em>The expected number of smooth fur hamsters (SS) in the next generation of 1000 hamsters is</em>: 390

What’s the important function of salt marshes
labwork [276]
Salt marshes have a whole range of functions. It plays an important role as a sediment trap. In this way, it regulates the water quality and helps stabilizing the coastlines. Salt marshes function as filtering systems and retain sediments, excess nutrients, toxic chemicals and disease-causing organisms

Write a paragraph explaining how genetic variation, reproductive strategies and environmental pressures have impacted the surviv
Andreas93 [3]

Answer: Genetics and Pressures

Explanation:

For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.

Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.

Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.
