Genetics 1
What do mitochondria's do in the cell?
What is the difference between Dominant and Recessive genes?
Dominant genes are always used, or shown. But Recessive genes are only shown when there are no Dominant genes.
Define Natural Selection.
When a species dies out because their adaptations could not help them live in their environment, which makes a new species with a adaptation that helps them live in their environment passes on and spreads through Reproduction.
Is cloning possible?
In theory, yes. You can add other genes into the original genes to make it work better or to make it look more similar to the original thing.
A rock, animal, plant, something that is preserved overtime in the ground.
What function in a cell controls the activities and carries the genes?
The nucleus
What are the differences between Homozygous and Heterozygous?
Homozygous is when you have two alleles that are the same. Heterozygous is when you have two different alleles.
Define Genetic Drift.
When one or more animals die out in their species by complete random because of things happening in their environment.
It can cause diseases, like Cancer. It can ruin the healthy part of fruits or vegetables and make it more unhealthy. It can add added sugars to make the fruits or vegetables not healthy at all.
What are different types of fossils?
Preserved plant fossils, animal bones, animal remains, rock fossils.
What 2 things do plant cells have that animal cells don't?
A cell wall, and chloroplasts.
Define Phenotypes and Genotypes?
Phenotypes are genes that are outside the human body, like eye color. Genotypes are what is inside the human body, like genetic makeup.
Define Migration.
When a species has to move to another environment because their environment is not livable to them anymore.
What are the advantages of GMO?
It can stop diseases and bacteria or bugs from getting in your food. It also can make the crops grow quicker.
What is extrusion?
Magma that pushes rock down into the earth.
What is the difference between the cell wall and the cell membrane?
The cell wall is the structure of the cell while the cell membrane controls what goes in and out of the cell.
When an allele has a Recessive gene will it be capital or lowercase when you are making a Punnett Square?
It will be lowercase, because it represents being Recessive.
A group of birds flew to a new home that had more food they could eat. Does this show Natural Selection, Genetic Drift, or Migration?
This is a form of Migration.
How does Gene Therapy work?
What is intrusion?
Magma seeping through layers of rock.
What cell function in a plant cell stores water?
The Vacuole.
If a baby's mother has brown hair, which is a dominant trait. And their dad also has brown hair. What is the probability that the baby will also have brown hair?
100%, two dominant traits will make the baby have that trait.
A type of monkey was born without a thumb finger. They started dying because they couldn't go up trees easily to hide from predators, or get food. Some of them started being born with a thumb finger and it eventually spread, making the monkeys without a thumb finger die out. Does this show Natural Selection, Genetic Drift, or Migration?
This shows Natural Selection.
What is Selective Breeding?
When you pick certain genes to put into other genes to create something specific.
What is an Index Fossil?
Index Fossils help you find what time period they were from.
