Having 2 different alleles means to have a pair of a type of gene i.e. for e.g. in sweet pea
there are 2 gene for seed shape, folower colour, flower position, pod shape, pod colour and are on homologous choromose and are knwon as allele of each other

What are genes with three or more alleles called?
this makes no scientific sense. A gene (which determines a phenotypic trait) can only contain 2 alleles. However codominace allows for multiple alleles to be chosen from, but only 2 picked for a gene. Also, if multiple genes determine a phenotypic trait that's polygenic inheritance.
What is a hybrid gene?
A hybrid gene is a gene that is formed from a combination of two different genes. It can be made by recombinant DNA technology. Hybrid genes possess at least one characteristic of both the genes combined.
How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
What is homozyous?
Having different alleles at one or more corresponding chromosomal loci.
Different forms of gene?
Alleles are the different types of genes.
What is Having two unlike genes for the same trait?
When two alleles differ from each other, such as Tt, it is called heterozygous, hetero meaning different. When alleles are the same (TT) it is called homozygous, homo meaning same.
What organism with two unlike genes of a trait is called?
A heterozygous has 2 different alleles for a trait.
What three ways are human traits controlled?
Single genes with two alleles, single genes with multiple alleles, and many genes that act together
What organisms with two alleles are called?
Genes
Which term did mendel us when referring to a trait with two unlike alleles?
Mendel used the term hybrid when referring to a trait with two unlike alleles.

What has two like genes or alleles?
Diploid organisms, like humans, have two alternate like alleles for every gene.

Why does each parent organism in the f1 generation have four alleles listed in figure 6.17?
Each parent has two genes with two alleles so there are four alleles.
