Dominance is when one gene completely takes over the phenotype, and codominance is when two genes are equally expressed.
For example:
Dominance: Red flower x yellow flower = red flower (red gene is expressed, but yellow gene isn't)
Codominance: Red flower x white flower = flower with red petals and white petals (both the red gene and the white gene are expressed)
What else can I help you with?
Is the inheritance pattern of the BRCA1 gene dominant or recessive?
The inheritance pattern of the BRCA1 gene is dominant.
When studying a pedigree how do scientists determine if a trait is dominate or recessive?
dominant only appears in the F1 generation as 4 recessive stays hidden or masked in the F1 generation
What is the relationship between two different genes for a trait in genetic inheritance?
The relationship between two different genes for a trait in genetic inheritance is known as gene interaction. This interaction can result in different patterns of inheritance, such as dominant-recessive or co-dominant traits, which determine how the genes are expressed in an individual.
When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
What is it called having a dominate and recessive allele?
Having a dominant and recessive allele is known as Mendelian inheritance, named after Gregor Mendel, the scientist who first described it. In this type of inheritance, the dominant allele masks the expression of the recessive allele in heterozygous individuals.
Is the inheritance pattern of the BRCA1 gene dominant or recessive?
The inheritance pattern of the BRCA1 gene is dominant.
What are the four complex patterns of inheritance?
Autosomal dominant, Autosomal recessive, X-linked recessive and X-linked dominant
What are some patterns of inheritance in humans?
Autosomal dominant Autosomal recessive X linked recessive.
What are some patterns of humans inheritance?
Autosomal dominant Autosomal recessive X linked recessive.

What type of inheritance that involves one dominant allele and one recessive allele is called?
The type of inheritance that involves one dominant allele and one recessive allele is called simple Mendelian inheritance or complete dominance. In this pattern, the phenotype of the organism will display the trait associated with the dominant allele, while the recessive allele's effects are masked when both alleles are present. An example of this is the inheritance of flower color in pea plants, where purple (dominant) flowers mask the expression of white (recessive) flowers.
Is hereditary deafness recessive or dominant?
Hereditary deafness can be caused by both recessive and dominant genetic mutations. Autosomal recessive inheritance typically requires two copies of the mutated gene for deafness to manifest, while autosomal dominant inheritance only requires one copy of the mutated gene. There are also other forms of inheritance, such as X-linked and mitochondrial inheritance, that can cause hereditary deafness.
Which versions of genes are dominant over others in genetic inheritance?
In genetic inheritance, dominant genes are versions of genes that are expressed over recessive genes. Dominant genes mask the effects of recessive genes when they are present together in an individual's genetic makeup.
What are the states that some alleles are dominant and others are recessive?
Mendel's law of inheritance.
