Genetics History
Father of genetics, studied peas
Who is Gregor Mendel?
The physical expression of a gene
What is a phenotype?
A random permanent change in an organisms DNA
(A change in the nucleotide sequence of a gene)
What is a mutation?
Spiral galaxy
What is the shape of our galaxy? (Milky Way)
Reproduction that requires two parents
What is sexual reproduction?
Scientist who first captured the image of the double helix DNA strand (photo 51)
Heterozygous
When the alleles of a genotype are not the same (such as "Rr" or "Bb")
Nucleotide
What is a molecule made of a nitrogen base, a sugar, and a phosphate group?
Hydrogen and helium
What are the main components of a star?
Cells that have pairs of chromosomes
What are diploid cells?
Square created and used to predict the possible genotypes of offspring
The genes (alleles) are the same and dominant
What is homozygous dominant?
Deletion, insertion, substitution
What are the types of mutations?
The Romans called him Mars, the God of War
Who is Ares, the Greek God of War?
Binary fission
What is cell division in prokaryotes that forms two genetically identical cells?
Francis Crick, James Watson, and Maurice Wilkins
Who are the scientists who won the 1962 Nobel Prize for their contributions to the study of genetics
Occurs when multiple genes determine the phenotype of a trait
What is polygenic inheritance?
An organism's genetic material
The Romans called her Venus, the Goddess of Love and Beauty
When a new organism grows by mitosis and cell division on the body of its parent
This chart shows phenotypes of genetically related family members
What is a pedigree chart?
Codominance
What occurs when both alleles can be observed in a phenotype?
It is called a double helix and is shaped like a twisted ladder
What is DNA?
Alpha Centauri or Alpha Proxima
What are the closest stars to our own? (4.2 light years away)
When some plants are cloned from just a few cells (the type of method)
What is a tissue culture?
