Selective Breeding
Can you Selectively Breed 2 animals?
What did he discover?
He discovered that by breeding specific plants together, they will get certain traits.
What do genotypes code for?
phenotypes
What is a trait?
a distinguishing quality or characteristic, especially one belonging to a person.
What is an example of 2 alleles in which the outcome will be the dominant gene?
RR or Rr
What does it mean to Selectively Breed 2 animals?
To choose 2 breeds and mate them to create the animal you like.
What plant did he work with?
Pea plant
What are phenotypes?
The physical trait.
Ex: Blue eyes, Brown Hair, etc.
What is heredity?
the passing on of physical or mental characteristics genetically from one generation to another.
What are the alleles for the genetic outcome to be recessive?
rr
If you let 2 dogs breed freely, is it still Selective Breeding?
No
What are Gregor Mendel's 3 laws?
The Law of Segregation, the Law of Independent Assortment, and the Law of Dominance.
What is a Homozygous Dominant genotype?
RR, or 2 dominant alleles.
What is an allele?
Alleles are alternative versions or variants of a specific gene located at the same position (locus) on a chromosome.
If the genotypes are rr, what is the genetic outcome?
The recessive trait will show.
What are some animals that can be Selectively Bred?
Dogs, Cats, Horses, Cattle
What was his job?
A gardener
What is a Homozygous Ressicive genotype?
rr, or 2 Ressicive alleles.
What is a chromosome?
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells, made of protein and a single molecule of DNA.
If the genotypes are RR, what is the genetic outcome?
The dominant trait will show.
Can you Selectively Breed humans?
yes
How many traits did he study?
7
What is a heterozygous genotype?
Rr, or 2 different alleles.
What are genetics?
Genetics is the branch of biology studying heredity.
If the genotypes are Rr, what is the outcome?
It will be the dominant trait.
