What is the difference between a herezygous and a homozygous?
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
What terms mean genetic composition?
Genetic composition refers to the complete set of genes in an individual's DNA. It includes all the alleles and variations that determine an organism's traits. It can also refer to the specific combination of alleles present in an individual's genotype.
The term is used to refer to an individual living thing?
An organism.
Do alleles have to be the same trait for example Tt or can they have two traits combined for example Tb?
In classical genetics, alleles refer to different forms of the same gene that can result in different traits. An individual would not have an allele represented as "Tb" for example - instead, they may have "T" and "b" as separate alleles that influence different traits. Each allele typically represents a specific version of a gene that contributes to a particular characteristic.
What is heterogenous in genes?
Heterogeneous genes refer to genes that have different variations or versions (alleles) in a population. This variation can lead to differences in traits or susceptibility to certain diseases among individuals. It contributes to genetic diversity within a population.

Compare homozygous alleles to heterozygous alleles?
Homozygous alleles refer to having two identical alleles for a particular gene (e.g., AA or aa), while heterozygous alleles refer to having two different alleles for a specific gene (e.g., Aa). Homozygous individuals will express the same trait, while heterozygous individuals may show a mix of the traits associated with each allele.
What is the difference between heterozygous and homozygous alleles?
You're looking at a gene which contains 2 alleles (meaning variations of that gene). Let's call it "A."Remember that you get 2 copies of EACH gene (one from mom, one from dad).

What does tt mean in genenitics?
In the study of genetics, we often refer to things call Alleles. These things can help us work out the chance of a particular person having a particular characteristic.In genetics we call lower case letters recessive alleles, for example 't'However, alleles always come in pairs, one from the mother, one from the father so it would be tt.I don't want to over complicate things but there are also dominant alleles which are shown as upper case letters, so 'T'.tt is basically the recessive genotype of a particular characteristic.We call the two alleles together a genotype.Hope this helps!
Are homozygous true breeding for a particular trait?
Homozygous individuals have two identical alleles for a particular trait. True-breeding individuals are homozygous for a trait and will always pass on that trait to their offspring. So, if an individual is homozygous for a particular trait and true-breeding, it means that all of its offspring will also express that same trait.

What is typus?
"Typus" can refer to a German term for "type" or "standard." In medical contexts, "typus" may refer to a specific symptom pattern that characterizes a particular disease. It can also refer to a general term in biology to describe a specific form or variation of an organism.
What is hom and het?
Hom and het are abbreviations commonly used in genetics to refer to genotypes. "Hom" stands for homozygous, indicating that an individual has two identical alleles for a particular gene. "Het" stands for heterozygous, indicating that an individual has two different alleles for a particular gene.
What does a lower case letter of an allele refer mean?
A lower case letter for an allele typically indicates a recessive trait. In genetics, alleles are alternate forms of a gene that can produce different effects on an organism's phenotype. The convention of using lower case letters for recessive alleles helps distinguish them from dominant alleles, which are usually represented by capital letters.
What is the condition whereby a trait is determined by three or more alleles called?
The condition whereby a trait is determined by three or more alleles is called multiple allelism. Multiple alleles refer to the presence of more than two alleles of a gene within a population. This can result in various combinations of traits and phenotypes.
