Mendel's Laws
Mendel used what type of organism for his experiments
pea plants
homozygous vs heterzygous
aa/AA vs Aa
When many forms (more than 2) of a gene exist, it is called...
multiple alleles
traits that follow mendel's 3 laws are called
Mendelian genes
Some alleles are dominant, and some are recessive
Law of dominance
phenotype vs genotype
phenotype-the way it is EXPRESSED
genotype-the GENETIC basis
describe (or give an example) of a heterzygous phenotype
This is a "blend." This phenotype lies between both hom phenotypes
A parent has 2 alleles, and gives one to the offspring. What is the probability for each allele that the offspring will inherit it?
50/50
The 2 alleles for each gene are placed in two separate gametes
The law of segregation
1 version/variety of a trait, located on a homologous chromosome
allele
Genes that are close together on the same chromosome and tend to be inherited together
linked genes
What is a F1 generation?
First generation produced from a cross between 2 individuals
The inheritance of one gene does not effect the inheritance of another gene
The law of independent assortment
1 section of DNA, that codes for a particular trait.
gene
Traits with a spectrum of phenotypes typically have this pattern of inheritance
polygenic inheritance
Separation of ALLELES happens in which phase of meiosis
Anaphase I
Linked genes "violate" which of Mendel's 3 laws
The law of independent assortment
dominant vs recessive gene
recessive gene is masked/covered by the dominant
Incomplete dominance vs Codominance
Incomplete-nether allele is fully dominant or recessive
Codominance-BOTH alleles are fully dominant
For 1 gene, a heterozygous individual can produce how many different gametes
2
