Homozygous is a description of alleles that are the same (HH,hh): either both dominant or both recessive. Heterozygous is a description of alleles that are different (Hh): one dominant, one recessive.
They are the same
The words homozygous and heterozygous don't apply to the chromosomes that you have but instead refer to the differing alleles (versions) of a gene you have. For example if you have a brown hair allele and a blond hair allele, you are said to be heterozygous for the hair colour gene. If you have two of the same allele you are said to be homozygous. As such one person will heterozygous for some of the thousands of human genes and homozygous for others. If you are XY it means you are male, and XX means you are female.
To determine if a plant is homozygous or heterozygous, you would need to test cross it with a homozygous recessive plant. If the offspring show the recessive trait, the original plant is heterozygous; if all offspring show the dominant trait, the original plant is homozygous.
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.
Heterozygous vs. Homozygous: These terms refer to genetic mutations. There are two copies of the protein codes in the genetic code. If one copy is normal and the other has the mutation, it is said to be heterozygous. If both copies have the mutation, it is said to be homozygous. For example: A/A -- homozygous. A/a -- heterozygous. a/A -- heterozygous. a/a -- homozygous.Homologous refers to the pair of chromosomes that are the same whilst Homozygous refers to the fact that alleles of a gene pair are the same
heterozygous
homozygous- TT; heterozygous- Tt :)
Yy is a heterozygous genotype. Homozygous would be YY or yy.
Yes - Hh is heterozygous. HH is homozygous, and hh is homozygous.
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
Homozygous
AA could be either homozygous or heterozygous, depending on whether the individual inherited the same allele (A) from both parents (homozygous) or different alleles (Aa) from each parent (heterozygous).
A cross between two individuals that are homozygous for different alleles will only produce heterozygous offspring. This is because each parent can only donate one type of allele, resulting in all offspring being heterozygous for that particular gene.
homozygous
Homozygous refers to having two identical alleles of a particular gene, while heterozygous refers to having two different alleles of a particular gene. In homozygous individuals, both alleles are the same (e.g., AA or aa), while in heterozygous individuals, the alleles are different (e.g., Aa).
There are 3 probabilities: dominant homozygous, recessive homozygous, or heterozygous.
