inheritance variation and evolution
genetic diagrams
You have two versions of every gene in your body one of each chromosome and a pair
In an organism you have two for particular gene that are the same then in Homozygous For that trait if it’s too for a particular gene or different then it’s heterozygous
All genes exist in different variations called alleles
If the two are different only one can determine what chemistry sticks is present for the characteristic that shine it’s called dominant and the other one is called recessive
However most characteristics are controlled by several genes interacting
For an organism to display over a set of characteristics both must be recessive but to display a dominant characteristic the organism can be either CC or Cc Because the dominant overall the recessive one in the plant/animal/other organism
Different genes control different characteristics some characteristics are controlled by single gene
Your genotype is the combination of alleles you have
What jeans do you inherit control what characteristics you develop
inherited dioreders
Treating disorders cost the government and the taxpayers a lot of money
There are laws to stop it going to fuck at the moment parents cannot even select the chat sex of the baby unless it’s for the health reason
It will help to stop people suffering
variation
Do you know types is all the Jeeves and alleles That’s an organism has
And organisms Geo types affects its fellow types the characteristics that is displayed
Variation cannot be genetic this means its course by differentces in genotype
And organisms jeans on heritage passed down from the parents
when something i significantly different like the first colour of an animal in a certain climate it can help it dial survive say a polar bear it’s Wi-Fi helps it survive because it blends in with its environment the fair was once brown it’s now white tutor variation and natural selection
evolution
A new disease kills them all
They can’t compete with another new species for food
A new predator kills them all e.g. humans hunting them
A catastrophic event happens that kills them all e.g. a volcano eruption rape collision with an astroid
The environmental changes to quickly e.g. destruction of habitats
