Organisms can be classified in to taxonomic levels:Domain,kingdom,phylum,class,order,phylum,genus,species.
Adaptation:acclimitizing to particular environment or food etc.,adaptatons helps animal to survive,Adaptation can be how an animal looks or behaves.
Wallace :He is an naturalist have ideas similar to darwin ,that species changed overtime because of theri struggle for existence.
Biosphere:Sum of all ecosystems.
Allele:Alternate expression of gene .
Anaphase:Chromosomes separated and moves towards the poles
Bottle neck effect:Decrease in the population due to humans or environmental interferance.
Charles darwin:He is an naturalist,biologist ,his theory of evolution explains how species of organisms change overtime
Codominance:Both alleles og gene are expreessed in heterozygous offspring
Community:Two or more species interacting with each other .
Cytokinesis:cytoplasm of single eukaryotic cell divides in to two daughter cells.
Diploid:cell with 2 sets of chromosomes
Dominant allele:Dominant allele is allele that is expressed when two different alleles are presant .
Ecosystem:it includes both biotic and abiotic components
Eukaryotic:organisims with definite nucleus and nuclear membrane
Evolution:Gradual chnge in species over time .
Founder effect :It occurs if small number of individuals colonize a new area
Gene:segment of DNA that codes foe protein
Gene flow :Movement of alleles from from one population to another .
Gene pool:Total number of genes in aparticular population
Genetic drift:Change in gene pool population by chance
Genome:Organisms entire hereditary information
Genotype:genetic make up of organism
Gregor Mendel: He is "father of modern genetics,
Haploid:Organism with single set of chromosomes
Heterozygous:made up of two different alleles
homologous pair:Chromosomes with similsr genes one from mother and another from dad.
Homozygous:made up of two similar alleles
Hybrid:Offspring of crosses between two different species
Malaria:Malaria is a mosquito-borne infectious disease caused by plasmodium
Meiosis: reduces the chromosome number by half,results in 4 daughter cells
Metaphase:Siater chromatids line up in center od spindle fibers
Mitosis:Having same number of chromosomes ,results in 3 daugther cells
Mutation:Change in organisms DNA
Natural selection :Process by which traits become more or less common in population
Non randon mating:Certain traits increase mating success
Organism:Made up of 2 or more cells
Phenotype:Observable characteristics of organism.
Population:Made up of number of organisms of same species
Prezygotic barriers:Block fertilization from happening
Postzygotic barriers:Occurs after zygote is formed
Prokaryotic:Primitive organisms with no distinct nucleus
Recessive allele:It is expressed when paired with other recessive allele
sex linked genes:Genes that are located on sex chromosomes
Sickle cell anemia:Genetic disorder in which RBC cells becomes sickle shaped
sister chromatids:Two identical copies of chromosomes connected by centeromere
Telophase:Chromosomes are at poles and forms 2 cells .
Temporal lobe:Paired lob of brains that helps in understanding speech
vestigial:These are structures that are no longer in use but are functional in ancestors.
