9 - Populations Flashcards
F1 generation=
*Dominant and recessive traits.
Mendelian ratio= the _____ ratio
Phenotype=
Genotype=
Homozygous=
Heterozygous=\
F1 generation= first filial.
*Dominant and recessive traits.
Mendelian ratio= the 3 to 1 ratio
Phenotype= the expression of a trait.
Genotype= an individual’s genetic makeup.
Homozygous= two dominant or two recessive alleles.
Heterozygous= one dominant and one recessive. (hybrid)
Law of segregation=
Law of independent assortment=
Karyotype=
Sex-linked=
Law of segregation= states that alleles segregate independently of each other when forming gametes.
Law of independent assortment= states that genes located on different chromosomes assort independently of each other.
Karyotype= map of the chromosome.
Sex-linked= when a gene is found on a sex chromosome.
Gene Pool=
Evolution=
Niche=
r-selection=
k-selection=
Gene Pool= the total of all alleles in a population.
Evolution= is a change in the gene pool.
Niche= the way in which a species exploits its environment.
r-selection= large numbers of offspring that mature rapidly with little or no parental care.
k-selection= small brood size with slow maturing offspring and strong parental care.
Divergent Evolution=
Convergent Evolution=
Divergent Evolution= exists when two or more species evolving from the same group maintain a similar structure from the common ancestor.
Convergent Evolution= when two species may independently evolve similar structures.
Symbiosis=
Mutualism=
Commensalism=
Parasitism=
Symbiosis= relationship between two species.
Mutualism= relationship can be beneficial for both. :-):-)
Commensalism= beneficial for one and not affect the other :-):-|
Parasitism= beneficial for one and detrimental to the other. :-):-(
