Are capital letters heterozygous?
If an organism is heterozygous, the capital letter always comes first. For example: Tt NOT tT.
Is homozygous capital or lowercase?
When a particular gene has identical alleles (versions) of chromosomes inherited from both parents, the gene is homozygous. A homozygous trait is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.
Is Capital aa heterozygous or homozygous?
Heterozygous is a genetic condition where an individual inherits different alleles of a gene from the two parents. Homozygous genotypes are represented as AA or aa for homozygous-dominant or homozygous-recessive conditions, respectively. Heterozygous genotypes are represented by Aa genotypes.
Is heterozygous dominant capital or lowercase?
But if the gene is heterozygous, meaning it has two different alleles, the capital letter will be the trait one will see in the animal. The capital letter is said to be the dominant trait and the small letter is the recessive trait.
What type of allele is shown as lowercase letters?
When writing a genotype, the dominant allele is usually represented by a capital letter, while the recessive allele has a lowercase letter.
How can you tell the difference between heterozygous and homozygous?
The difference between these traits is: Homozygous traits have two copies of the same allele. Heterozygous traits have one dominant allele and one recessive allele.
