Genetics - Basic Info
Chromosomes
Types of Genes
DNA/Genes
Punnett Squares
100
The scientific study of heredity.
Genetics
100
Humans have how many pairs of chromosomes?
23
100
A gene that always takes over if present. Capital letters are used to represent.
Dominant
100
Located inside the nucleus - each cell has around 6 feet - codes for your traits/book of life
DNA
100
What replaces the ??
aa
200
The passing of traits from parents to offspring.
Heredity
200
How many total chromosomes do humans have?
46
200
Only shows up if there are two of these genes present. We use lower case letters to represent.
Recessive
200
DNA's shape
Double Helix
200
What replaces the ??
Qq
300
A disease or disorder that is inherited genetically.
Genetic Disease
300
The chromosomes are located in what part of the cell?
Nucleus
300
When there are two dominant or two recessive genes together.
Homozygous
300
Contains the directions for what traits you have. They come from DNA. All living things have these. Humans have around 22,000
Genes
300
What is the percentage of flowers that will be Homozygous Dominant?
25%
400
When a gene goes through a change that can be beneficial, neutral or harmful.
Mutation
400
A female has what letter combination on the 23rd chromosome?
XX
400
When there is a dominant and a recessive gene together.
Heterozygous
400
Physical description of the observable trait, ex: blue, brown, short, tall, round - If I take a PHOTO I will see this.
Phenotype
400
What is the percentage of offspring that will be heterozygous?
50%
500
Different forms of genes - we use letters to describe the different forms of genes.
Allele
500
A male has what letter combination on his 23rd chromosome?
XY
500
Your internal letter combination - your alphabet soup - your genetic combination
Genotype
500
Inside of the DNA, part of a gene - known as the "workhorse" of the cell.
Protein
500
Based on the punnett square - what percentage of the offspring will be homozygous recessive?
50%
