Why is Mendel a recognized scientist?
He's work with garden peas not explained the mechanism of gene inheritance for plants, but provided a basis for understanding heredity.
What is the difference between Dominant and Recessive genes?
dominant: determine the genetic trait

reccesive:overruled by the dominant gene
A pair of factors, or genes, separate or segregate during the formation of sex cells. This process is often referrred to as the law of_________________.
Segregation
What is the difference between Genotype and Phenotype?
genotype: refer to th egenes of the organism
phenotype: refer to the observational traits
What is the difference between Homozygous and Heterozygous?
heterozygous:when the gene pair are different
Homozygous:when the two gene pairs are the same
What are Alleles?
a)two or more alternate forms of a gene
b)one pair of contrasting traits
c)crosses of the genetic code
A)
Alleles are the two or more alternate forms of a gene

What is a monohybrid cross?
a) a type of punnett square
b) an inhereted cross from the
parents
c) a pair of contrasting traits
d) genes that effect many
characteristics
c) Monohybrid coss involves one gene pair of contrasting traits.
What is a Test Cross?
A test cross involves crossing an F1 offspring with a homozygous ressecives individual. is used to see if the F1 is Homozygous or Heterozygous for a characteristice such as tallness.
How do you know if Incomplete dominance has occured?
When twogenes are equal dominant, they interact to produce a new phenotype.
Ex.:Red bull and a White cow make a Roan calf.
