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.
Homozygous refers to having two identical alleles for a trait, while heterozygous refers to having two different alleles for a trait. In other words, homozygous individuals have either two dominant or two recessive alleles, while heterozygous individuals have one dominant and one recessive allele.
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.
Homozygous
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
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
There are 3 probabilities: dominant homozygous, recessive homozygous, or heterozygous.
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).
