What is Genetics?
Genetics is the branch of biology that studies heredity.
Who discovered genetics and how did he do this?
Gregor Mendell discovered genetics and he did this by studying pea plants.
Domintant and Recessive alleles
The domintant allele is the allele that is expressed.The recessive allele is the allele that is being overpowered by the domintant allele.
Heterozygous and homozygous
Heterozygous is one big letter and one little letter. Homozygous is two big letters.
Phenotype and Genotype
Phenotype is the physical appereance of the offspring. Genotype is the alleles of the organism or offspring. Ex. AA, Aa, etc.
Incomplete dominace
This is where no of the parent alleles are shown in the offspring. Like a red flower and a white flower makes a pink flower.
Codominance
This is where both the parents alleles are expressed equally in the offspring. Like a blue fish and a red fish make a blue and red fish.
Multiple Alleles
Multiple alleles is any set of two or more alleles. They are used to determine eye color, skin color, and other complex traits.
Sex-Linked traits
These are traits determined by the genes on the sex chromosome. Colorblindness is a sex-linked trait.
