Week 5 - Allele Frequency - Hardy-Weinberg Formula

Question 1

The differences among individuals in a population.

Answer 1

Variation

Question 2

Number of individuals sharing a gene pool

Answer 2

Population Size

Question 3

the combination of all the genes (including alleles) present in a reproducing population or species.

Answer 3

Gene Pool

Question 4

The number of individuals in a population that can actively contribute to the gene pool of the next generation also as Ne.

Answer 4

Effective Population Size

Question 5

The number of occurrences of an allele in a gene pool.

Answer 5

Gene Frequency

Question 6

More than two sets of chromosomes in a cell or organism. (adj. polyploid)

Answer 6

Polyploidy

Question 7

The number of sets of chromosomes in a cell or organism.

Answer 7

Ploidy

Question 8

a particular section, group, or type of people or animals living in an area or country. a group of interbreeding individuals and their offspring.

Answer 8

Population

Question 9

Factors Affecting Population Size

Answer 9

Breeding Sex Ratio
Population Size
Breeding Groups
Fertility

Question 10

If one sex is rarer than the other in the population, it is likely that all members of that rarer sex will mate and reproduce. Therefore, the rarer sex will dominate the gene pool and it is more likely that genes of the rarer sex will be passed on to the next generation.

Answer 10

Breeding Sex Ratio

Question 11

If the population size (N) fluctuates, effective population size (Ne) will be dominated by the smallest gene pool.

Answer 11

Population Size

Question 12

If the population forms small groups for breeding (for example, a pride of lions), Ne will equal Ng (the population size of a group).

Answer 12

Breeding Groups

Question 13

Individuals within a population often vary in fertility; more fertile individuals will have a greater influence on the gene pool.

Answer 13

Fertility

Question 14

Under these ideal conditions (when Ne = N), after one generation (and assuming that there is no selection or mutation), the population’s gene frequencies will attain _____________.

Answer 14

equilibrium

Question 15

It is used to determine changes in allele frequency within a population over time. It states that when Ne = N, in the absence of selection or mutation, gene frequencies will achieve equilibrium after one generation.

Answer 15
