MEOISIS PT.2
SEXUAL REPRODUCTION
ADAPTIONS
100
A permanent change in the DNA sequence
What is Mutation
100
Behavior of chromosome during meiosis is responsible for most variation in each generation
What are species that reproduce sexually
100
(n=23)
What are possible combinations for humans
100
Unique combinations of parental genes formed during what
What is meiotic recombination and fertilization?
100
Inherited characteristics of organisms that enhance their survival and reproduction in specific environments
What are adaptions?
200
Mutation can change the what of an organism
What is phenotype
200
3 aspects contribute to this genetic variation
What is Independent assortment of chromosomes, crossing over, and random fertilization
200
Our two parents
What is the collection of gametes differing in combinations of chromosomes inherited from?
200
Producing offspring of varied genotypes
What is sexual reproduction?
200
Perceived adaption to environment and the origin of new species as closely related processes
Who is Darwin?
300
Mutations can be passed on from generation to generation if they occur in what
What are germ cells
300
Random orientation of pairs of homologous chromosomes at metaphase (meiosis 1)
What is Independent assortment of chromosomes
300
Produces recombinant chromosomes, individual chromosomes that carry genes (DNA) derived from] two different parents
What is crossing over
300
Enhanced productive success of parents
What is caused when environmental factors (pathogens) change rapidly?
300
New species
What is caused from ancestral form by gradual accumulation of adaptions to a different environment?
400
Balance between complete fidelity of DNA replication and a low mutation rate equals what
What is evolution of rich diversity of species
400
Represents one outcome of all possible combinations of maternal and paternal chromosomes
What is each daughter cell
400
Crossing over produces chromosomes with new combinations of what
What is maternal/paternal alleles?
400
An affect of gene combinations
What is the speed up of adaption?
400
Enhanced by caterpillar's flair for decorating (Gluing pieces of flower petals to body)
What is the reason for the difficulty of birds to spot this caterpillar that blends into flowers?
500
Faithful replication of the genome and repair of DNA damage are important for what
What is the functioning of an organism and ability to pass a complete genome to the next generation
500
(n=4)
What is the number of possible combinations for daughter cells formed by meiosis?
500
Important source of genetic variation in
