Mitosis
This process ends with 2 genetically identical daughter cells
Mitosis
This occurs during the Prophase I of Meiosis, swapping pieces of DNA on the same # chromosome
Genetic Recombination/ Crossing Over
When the presence of 1 or 2 dominant allele results in the same dominant phenotype.
Simple dominance
A gene that is X-linked recessive will show symptoms if present in a male. From which parent did he inherit this allele?
Mother
This is a group of organisms that can interbreed and live in the same location at the same time.
Population
This process ends with 4 genetically unique daughter cells.
Meiosis
This is a benefit of sexual reproduction, leading to redundancy of chromosomes
2 copies of each gene
When the presence of 2 different dominant alleles results in each dominant phenotype at the same time, unchanged by the other's presence
Codominance
This is a way in which genetic diversity can be decreased in a population (several correct)
Genetic drift, founder effect, genetic bottleneck, inbreeding
This type of selection selects against the average (middle) trait and selects for both of the most extreme versions of the trait
Disruptive
Through mitosis, a diploid parent produces ___ (ploid) daughter cells.
Diploid
This results from sexual reproduction, the combination of genetics from separate individuals
Fertilization
When 2 dominant alleles produce an intermediate phenotype, different from homozygous conditions.
Incomplete dominance
Likelihood of being a carrier for a recessive autosomal disease is 1 in 1000. Probability of 2 randomly selected parents being carriers is __.
1 in 1,000,000
This type of evolution occurs when closely related species develop two different variants of the same trait
Divergent
Through meiosis, a diploid parent produces ___ (ploid) daughter cells.
Haploid
During meiosis metaphase I, either maternal or paternal chromosomes of each pair will separate into each new cell.
Independent Assortment
When there are more than 2 alleles for one gene (ex. blood type)
Polymorphism or multiple alleles
Likelihood of being a carrier for a recessive autosomal disease is 1 in 1000. 2 known carriers reproduce. Their 1st offspring is a carrier. The probability of their 2nd offspring having symptoms of this disease is __.
1 in 4
This is a species role in its habitat.
Niche
T/F: Cancer cells cause problems for individuals because they limit cell division and result in early cell death.
False
This is the name of the cell formed after combination of sperm and egg.
Zygote
One phenotype trait is coded for by multiple genes (ex. skin color, height, metabolism)
Polygenetic inheritance
T/F: All past and present alleles of a population make up its gene pool.
False
Name an organism introduced to North America by humans
Ring-necked pheasants, cane toads, Russian olive, cats, kudzu, buckthorn, starlings, house sparrows
