What are the five conditions for change/stability?
Mutations, Natural Selections, Immigration/Emigration, Mating and Population Size

What is alternation of generation?
It is a sequential change during the life cycle of a plant in which a haploid stage (gametophyte) alternates with a diploid stage (sporophyte).

In a large population that strictly obeys the Hardy-Weinberg law, the frequency of "MM" genotype is 0.81.There are only two allels of interest: 'M' and 'm'). What is the frequency of 'M' allele?
.90
100
Define gene pool
all the genes possessed by an interbreeding population
200
Mutation lead to evolution. True or False
True and no mutations lead to equilibrium
200
Does meiosis occur in the sporophyte or the gametophyte?
Meiosis occurs in the diploid sporophyte
200
In a large population that strictly obeys the Hardy-Weinberg law, the frequency of "MM" genotype is 0.81.There are only two allels of interest: 'M' and 'm'). What is the frequency of the 'm' allele?
.1
200
Define genotype
the genetic make up of one individual. For example "AA", "Aa" or "aa". "A" and "a" are allels
300
Immigration leads to equilibrium and Emigration leads to evolution. True or False
False, both immigration and emigration lead to evolution. Limiting migration leads to equilibrium
300
Which is haploid, the sporophyte or the gametophyte?
The gametophyte is haploid
300
In a large population that strictly obeys the Hardy-Weinberg law, the frequency of "MM" genotype is 0.81.There are only two allels of interest: 'M' and 'm'). What is the frequency of the 'Mm' genotype?
.18
400
Which type of mating leads to equilibrium?
random mating

Compare the relative sizes of the sporophytes and gametophytes in nonvascular plants
The gametophyte is somewhat more prominent than the sporophyte. The green "leafy" moss we had in lab is the gametophyte. The sporophytes are small stalks that bear spore-containing capsules

In a large population that strictly obeys the Hardy-Weinberg law, the frequency of "MM" genotype is 0.81.There are only two allels of interest: 'M' and 'm'). What is the frequency of the 'mm' genotype?
.01
400
Suppose in a large population that strictly obeys the Hardy-Weinberg law the frequency of the "G" allele is 0.2 and the frequency of the "g" allele is 0.8. What is the frequency of the "GG" genotype?
.04
500
Why are large populations important in relation to allele frequency?
Small populations with accidents change the allele frequency
500
Compare the relative sizes of the sporophytes and gametophytes in vascular plants
The sporophytes are very large (like and oak tree) compared to the microscopic gametophytes (like pollen).

In a population that strictly meets all Hardy-Weinberg criteria for genetic equilibrium at all times there are only two variants or alleles of a gene that controls height. These alleles are “H” and “h.” The frequency of the “H” allele is 0.7. What is the frequency of the "h" allele?
Since there are only two possibilities: the frequency of the “h” allele is 1 - 0.7 = 0.3.
500
Suppose in a large population that strictly obeys the Hardy-Weinberg law the frequency of the "G" allele is 0.2 and the frequency of the "g" allele is 0.8. What is the frequency of the "Gg" genotype and the "gg" genotype?
