Traits and Reproduction
What is a trait?
An ability inherited from parents or is special to you.
What do you need to make a zygote?
You need a sperm and egg cell.
What are genes?
Genes are instructions to build protein structures.
For a dominant/recessive trait, do the offspring of identical parents always look like the parents?
No that would only happen during asexual reproduction.
What is a disadvantage of sexual reproduction?
It takes a lot of time.
What is a feature?
a feature is an unspecific trait such as hair, eye color, etc.
What is sexual reproduction?
Sexual reproduction is a type of reproduction that involves another being because to make the zygote in this type of reproduction, you need a sperm and egg cell.
What do genes do?
They instruct the directions to build protein structures.
What will happen when you breed an alien with straight antenna to an alien with curly antenna?
There will be a 50/50 chance of the antenna to be straight or curly.
What is adaptation?
What is adaptation?
A genetically diverse trait that develops, but doesn't come from your parents.
Gene leads to structure leads function leads to...
Trait
asexual reproduction is a type of reproduction that does not involve another being.
What are proteins?
Proteins are large, complex molecules essential for the structure and function of living organisms.
What is a structure?
The way something is built.
What is a chromosome?
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
How many ways are there to receive a trait?
There are 3.
What are 2 types of reproduction?
Asexual and sexual reproduction.
What do proteins do?
They build the protein structures.
What is a function?
The way something works.
What is Homozygous?
Having two identical alleles of a particular gene or genes.
What are the ways are there to receive a trait?
You can inherit them from your parents.
You can also have different gene versions that build different structures, making different traits.
You can have a mutation.
What do you need to make a offspring?
A sperm and egg cell and 2 beings.
How do the offspring of two parents that reproduce sexually differ from the offspring of a single parent that reproduces asexually?
The parents that reproduce sexually have offspring that look different from them but the parent that reproduces asexually will have offspring who are identical to them.
What is an advantage of sexual reproduction?
It creates genetic diversity.
What is Heterozygous?
Having two different alleles of a particular gene or genes.
