|
what is a character?
|
a heritable feature, such a color of a flower
|
|
|
what is a trait?
|
each variant for a character
|
|
|
What is true-breeding
|
a phenonomenon when to organisms of the same genes breed to have the exact same genes. Flower hat self pollinate is an example.
|
|
|
what is hibridization?
|
the cross of two true-breeding varietes of an organism.
|
|
|
what is a P-generation
|
the true-breeding parents in a hibridization.
|
|
|
what is the F1 generation?
|
P-generartion's offspring. Also known as first filial.
|
|
|
what is the F2 generation?
|
This is when the F1 population, and their offspring are this.
|
|
|
what are alleles?
|
these alternative versions of the gene. These are a result of slightly different DNA content at the homologous loci on chromosomes.
|
|
|
for each character, every organism inherits..?
|
one allele from each parent.
|
|
|
dominant alleles
|
will be fully expressed when inherited by organism.
|
|
|
recessive alleles
|
Will have no phenotype expression, unless both alleles are the same.
|
|
|
law of segregation
|
Created by Mendel.
EXAMPLE: if two parents give the same gene then all the children will have that gene. if there is two version then it's a 50% of getting one of the two alleles. |
|
|
law of independent assortment
|
Another Mendel's laws. Each pair of alleles will seperate independently during the gamete production peroid.
|
|
|
Homozygous
|
organisms with two of the same allele fro a trait. can be Dominant (RR) or recessive (rr)
|
|
|
Heterozygous
|
organism has two different alleles for a trait.
|
