RNA

Ribonucleic acid and a single strand of dna

Complete dominance

when both allese are dominant, RG

genotypic ratio

3:1

phenotypic ratio

3 blues to 1 white

Incomplete Dominance

Rr

Codomince

G 1G 2

X-linked/ sex linked traits

when a trait is linked by the X chromasomes

blood types

AB, A+,A-, B+, B-, 0+, O-

genotype

Bb/ the gene

penotype

puple, it shows what the final outcome will be

What is biodiversity

the differnt types of animals you will find in a certian area

dna

Deoxyribonucleic acid

nucleotide

building block for dna/rna

nitrogenour bases

adenine (A), thymine (T), cytosine (C), and guanine (G).

adenine

thymine

cytosine

guanine

protein

paires nitrogenous bases together

complamenty base

how the other bases paor up which each other

chromatin

when it is mixed with protein you get dna

CHromasome

it makes up dna, 23 pairs / 46 chromasomes

homologous chromesomes

when two chromasomes are exatly the same

gene

makes up your dna

allele

something that controls a certian triat

karyotype

an iduviocal set of chromasones

genetics

controls what you look and feel like

trait

eye coulor, hair coulor

dominant

when one trait is more power full that the other

ressive

then one trait requers the gene to appear twice so it can be visable

homozygous

two of the same resesive alles e

heterozous

one of each allele but one is dominant

mutations

when genes can be changed basied of of the envirorment, chemicals, ect

selective advantive

when somethinging is given a tria tthat cna help it survire better

adaptation

when something adapts to there envirorment better

adaptive rediation

when differnt animals of the same species have diffent trait to help them better in ther envorormant

extinction

when a specises is killed out

mutagin

when a chemicla substance causes a mutation

carcinogen

chemicla substances that can give you i high risk fo cancer

atifical selection

when human’s kill of a species, over hinting, ect

monoculter

when farmers change the dna of a plant to make it grow better

bio technogey

recombinant DNA

when it is chemicly dublicated

artifical insemination

when they chemicaly insert a spem into the utarus

gene theraoy

when they treat small abouts of your blood and and treat some disese

IVF - in vitro fertilization

where they remove a spem adn and egg and chemicly fetalize it, they insert it into the ularus
