Genetics and Inheritance Science Test
Terms in this set (18)
In sexual reproduction, what is the combination of DNA the offspring gets from both parents?
50% comes from mother, other 50% comes from father
In asexual reproduction, what is the offspring's DNA like in comparison to their parent?
Exactly the same
What do 100% of cells contain?
Genetic information from mom and dad
What does meiosis do?
It produces genetically unique gametes due to independent assortment and crossing over.
What are pedigrees?
They are diagrams that record the appearance of certain traits in a family's history.
What can be determined using a pedigree?
The study of heredity and the variation of inherited characteristics.
The passing on of physical or mental characteristics genetically from one generation to another.
Dominant vs. Recessive
Dominant (BB) traits overpower traits that are recessive (bb) and are homozygous
A section of DNA that occupies a place on a particular chromosome. Each gene codes for a specific protein and influences characteristic development
Means completely one trait-BB or bb, can be dominant or recessive
Means each parent passed down a different variation of a trait. Bb
Not heterozygous at all...completely homozygous. (whole family lineage)
Genotype refers to allele combination in genes...example: 50% GG
Phenotype refers to physical description that genotype descries...example: 50% Green
Complete, incomplete, co-dominance
Complete dominance: One trait completely takes over
Incomplete dominance: Not completely takes over=mix
Co-dominance: two separate traits both visible=two traits are companions
