Reproduction
Is the process of producing a new organism
change in a species over time
Evolution
number of daughter cells produces
2
is the study of how traits are passed from parent to offspring by looking at genes
genetics
Meiosis
small sections of DNA on a chromosome
Genes
Became the ship's naturalist/Voyage of the Beagle
Charles Darwin
type of chromosome number in daughter cell
diploid (full set)
the passing of traits from parent to offspring
heredity
crossing over creates variations in the offspring's trait
prophase
Diploid
evolution
chromosomes line-up in the middle
metaphase 2
alleles describe a genetic factor that is always expressed
dominant
daughter cells undergo a second division; much like mitosis
meiosis II
DNA is like blueprint or
Instructions
Occurs when populations of the same species evolve to become different genetically
Speciation
2 identical DNA strands, called chromatids, are held together at a region is called
centromere
the physical trait that an offspring expresses as a result of the genotypes
phenotype
spindle fibers attach to each chromosome
metaphase I
4 Nitrogen Bases that make the Rungs of the ladder
Adenine, Thymine, Guanine, Cytosine
occurs when population become divided by physical barriers that keep populations from mating
Geographical Isolation
is the process in which the nucleus divides to form two new nuclei that have the same genetic information
mitosis
two categories of genotypes
homozygous & heterozygous/hybrid
Mitosis & Meiosis
