Question
Chapter 54, Problem 11IQ
Summary Introduction
To determine: The population distributions after 20 years.
Introduction: The human population curve predicts the different demographic trends in birth and death. An example is if the age-specific birth and death rates changes, then the population of Sweden remains the same. In contrast, the population pyramid of Kenya shows the higher birth rates, with decreased life span and lead to explosive future growth.

- What is the relationship between the population's surviving members and the environment? and what role do genetics play in population change?arrow_forwardOnce upon a time there was a population of hippies living in an isolated commune called Gone. They had been there for generations, and all members were homozygous for a gene that gave them a preference for crafting necklaces out of green beads, so that every individual had the genotype GG at this locus. In another isolated commune, called Yonder, was a population of hippies that had a genetic propensity for making necklaces out of yellow beads, and everyone was homozygous for a different allele at the same genetic locus; their genotype was YY. Last year (prior to our current social isolating) everyone repaired their W buses, and a giant gathering in celebration of the 50th anniversary was held at the Oregon Country Fair. The next few questions will ask you about these two populations that came together at the fair. Genotype Observed Expected (0-E) (0-E)2 (O-E)?/E GG 81 79.2 81-79.2-1.8 1.82=3.24 3.24/79.2=0.04 12.96/105.6=0.

If you have a population with r =0.046 , what is the doubling time?arrow_forward
- Why is the minimum viable population size smaller for a geneticallydiverse population than for a less genetically diverse population?arrow_forwardA population has a current size of 100 and time steps are measured in years.

- In a population that is in HWE, the frequency of the homozygous recessive genotype is 0.09. What is the frequency of individuals that are homozygous for the dominant allele? Provide summationarrow_forwardDoes the genetic difference between populations increase with increasing geographic distance?arrow_forwardWhen the frequency of sitters is 0.75 (see Figure 6.22), the fitness of rovers is much higher than that of the sitters. So why don’t rovers quickly and completely eliminate the sitters in this population? Don't write from any online source..arrow_forward
