science Genes

What is a genotype?

Letters eg BB Bb bb

two alleles that are present

What is a phenotype?

The words eg. purple short hair long hair

what you can see

What is heterozygous?

It is having two different versions of a particular Gene One inherited from each parent 

What is homozygous? 

Having two identical Versions of a gene Inherited from each parent

What is an allele?

 

An allele is a specific variation or form of gene

What always happens with homo And heterozygous

 there are always two jeans and they  both are inherited by one parent 

Parents are always

 Homozygous

 first generation is

 hetero

What is incomplete dominance 

Alleles  present and they Blends together

What is codominance

alleles are present and both are seen

Multiple alleleism 

When there are more than two alleles possible for a given Gene 

 what are the different mutations

 Substitution

 Insertion

 Deletion

What is a mutation

 A random change in a Nucleus sequence or Nucleotide sequence (they mean the same thing)

Mutations can be

 Inherited

 Does your body usually find corrections? 

Yes

 What helps find Mistakes

 Enzymes correct the mistakes

 what is the second generation

 

Monohybrid cross

what is a Monohybrid cross

a genetic mating experiment between two organisms that are each heterozygous for a single trait 

What is heredity

 passing of traits from parent to offspring

 what is a trait

 a genetic characteristic which is passed from the parent to The Offspring

Eg  eye color

 what is another word for Gene

 allele

What is genetics

 the scientific study of heredity

What is a dominant gene

It's the chemically stronger Gene

 what is a recessive gene

 the weaker Gene

  it's only recessive if there are two small letters 

 

What is AB 

Codominance
