Meiosis
Process which creates egg and sperm cells, resulting in variation.
Meiosis
This was the scientist who first began studying heredity and genetics.
Gregor Mendel
This is an organism's genetic makeup.
Genotype
This type of organism has 2 dominant alleles for a trait.
Homozygous Dominant
This occurs when 2 traits are not fully dominant, causing a mixture of the traits.
Incomplete Dominance
Meiosis results in this many cells
4
This is the study of heredity
Genetics
This is an organism's physical appearance.
Phenotype
This type of organism has 2 recessive alleles for a trait
Homozygous recessive
This occurs when 2 traits are dominant, and both are fully displayed.
Codominance
The daughter cells in meiosis have only 1 set of chromosomes, making them ___________.
Haploid
This is the passing of physical characteristics from parent to offspring.
Heredity
This shows all of the possible outcomes of a genetic cross.
Punnett square
A homozygous dominant mother and homozygous recessive father will have children with the ________ phenotype.
Dominant
A Blue and Red flower are bred. The alleles show incomplete dominance. What is the phenotype of the children?
Purple
Crossing over refers to _________.
Mixing of DNA
Factors that control traits are called this.
Genes
How many dominant alleles are needed for a particular trait to show up?
1
In a monohybrid cross, 2 heterozygous parents have children with this phenotypic ratio:
3:1
A black cow and white cow are bred. The alleles show codominance. What is the phenotype of their children?
Black and white spots
Crossing over occurs during _________.
Prophase I
Different forms of a gene are called this.
Alleles
An organism with 2 different alleles for a trait is called a ______.
Hybrid/heterozygous
In a dihybrid cross, 2 heterozygous parents have children with this phenotypic ratio:
9:3:3:1
A mother with blood type AO and a father with blood type AB. What percentage of their children will have type B blood.
25%
