What does genotype ratio mean?
It is the ratio that tells the type of combonations of the genetic code. Ex: 1:2:1 (one TT, two Tt, one tt)
What does phenotype ration mean?
It is the ratio telling what trait will appear. Ex: 3:1 (the combonations could be TT, Tt, Tt, tt)
What does allele mean? List some examples.
a distinct form of a gene that codes for a certain trait. Ex: eye color, ear size, eye size
Explain what a dominat trait is.
a trait is expressed when one allele is present
Explain what a reccessive trait is.
a trait is expressed when pair of alleles
What does homozygons/homozygous mean?
Homozygons is when a living being is pure genes. same letters (TT, tt)
What does heterozygons/heterozygous mean?
Heterozygons is when a living being has different gene. different letters (Tt, tT)
What does adenine mean? Which other base pair does it go with?
one of the halves that makes up one of the generic codes. It goes with Tymine. This genetic code makes up how protein is made. It also gives living creatures specific traits.

What does guanine mean? Which other base pair does it go with?
one of the halves that makes up one of the generic codes. It goes with Cytosine. This genetic code makes up how protein is made. It also gives living creatures specific traits.
What is a chromosome?
a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
What does DNA stand for?
