Where are the chromosomes found in the cell?
Mitochondria
Nucleus
Cytoplasm
|
are the different versions of a particular gene.
|
Our body cells contain two copies of each chromosome, one from our mother, and one from our father. This means that we also have versions of each gene (each different version is a different allele).
|
Humans have two copies of each gene (alleles). If both alleles are the same, the person is said to be __________ for that gene.
Genomic
Homozygous
Identical
Heterozygous
|
Humans have two copies of each gene (alleles). If the two alleles are different, the person is said to be __________ for that gene.
Genomic
Identical
Homozygous
Heterozygous
|
Alleles can be either dominant or .
|
Charlie is heterozygous with one dominant allele and one recessive allele.
Which allele will be expressed?
The recessive allele
The dominant allele
|
In order to be expressed, how many recessive alleles must be present?
0
1
2
|
What is a phenotype?
The combination of alleles that an organism has for particular gene
The presence of two recessive alleles
The characteristics an organism has as a result of their genotype
|
If a mouse has one allele for brown fur, and another allele for black fur, would they be considered homozygous or heterozygous for that gene? Homozygous Heterozygous
|
If the brown fur allele was dominant, and the black fur allele was recessive, what colour would the mouse be? Brown Black Blonde
|
So in summary, the of the mouse is a brown fur allele and a black fur allele, whilst the is brown fur.
