-two alleles are dominant
-both proteins are functional
example: red flower + yellow flower = orange flower
The case in which the heterozygote displays characteristics of both alleles
F1 generation- the offspring from the parents in the P generation
F2 generation- self-fertilization or cross of two F1 results in F2
The ratio of heterozygous and homozygous, the aberration)
Allele pairs for different genes separate independently in meiosis, so the inheritance of one trait generally does not influence the inheritance of another trait. (The exception, unknown to Mendel, occurs with linked genes)
abnormal cells that are not the same shape as normal cells, oval shaped norm rounder
population move from their native land, for example: when settlers to the new world and there was a red head on the boat there will be more red heads in the new world then back from the original land
emigration or immigration where individuals moving out or in to a pop. Can change the allele frequencies of those pop
large scale evolutionary changes involving the origin of new group of organism the accumulated effect of microevolution over a long period of time
the mechanism of evolution that occurs when individuals with one version of a inheritable trait have greater reproductive success then do individuals with a different version of the trait
when + how often a species reproduces and how many offspring it has.
Military purposes for example Light Chariots Changes in battle strategy
Plucking of hairs, wrestling, voices, venders selling their wharves
Made a stick into a brush its invention because they changed the shape of the stick
as a structure for measuring the Nile River's clarity and water level during the annual flood season.
a wooden pole attached to a bucket
used to get water to the farm
1600 bathers used all the roman teaturey to build it 27 acres
Culture: Ostrogothic Religion: Arian (Christian)
Roof structure references building in Germany where he's from
Construction technology from Syria
Protected by deserts on its western and eastern frontiers, Egypt was safe from invasions for many centuries In Egypt there were very few slaves, only foreign captives or criminals
horse shoes and horse collar it didn’t choke the horses an agricultural revolution unparallled since the first invention of tillage. Its elements-the heavy plow, open fields, three-field rotation, and horse harness-accumulated and consolidated into a new agrarian system
part comes off and broken part fully grows back again
female produces an egg and with no help with the male
some species can make hybrids spices even if the chromosomes don’t match they can still put make a hybrid animal for example a horse has 46 chroms a zebra has 62 chroms they can make a zorse but these Hybrids can’t produce an offspring with another hybrid. Those some hybrids can mate they just need to have similar chromosomes.
3 requirements for evolution by natural selection to occur
Physical, physiological/biochemical, behavior
A bacterium, plant, or animal that has been genetically modified to carry one or more genes from an organism of a different species.
Carries different DNA from Different organism.
