Alleles. Different molecular forms of the same gene. Can be more alleles than a pair, though. Blood types, for instance. A, B, O.
A pair of alleles for a trait are the genotype for that trait, and determine the expression (phenotype) of the trait.
23 from each parent... that's a total of 46 genes from both parents :D
Yes - they each carry half the genes needed to make a complete zygote.
to put it simply as possible DNA (or Deoxyribonucleic Acid) form up genes which carry on looks, ect from your parents to you. you get an equal amount of genes from each of your parents
Very slowly. Each generation has some differences from the preceding generations. The survivors from one generation pass their genes on to subsequent ones. A trait that increases survival rate is passed on more frequently than a trait which is detrimental to procreation.
Evolution. Each generation has some differences from the preceding generations. The survivors from one generation pass their genes on to subsequent generations. A trait that increases survival rate (resistance to an insectide) is passed on more frequently than a trait which is detrimental to procreation.

Each trait characteristic of a plant is determined by epigenetic marks. Epigenetic marks affect flowering time and architecture in plants, and these marks are passed on for many generations.
genes
Yes, that is correct. Each trait is controlled by genes, and genes exist in different forms called alleles. For any given trait, an individual can have two allelesβone inherited from their mother and one from their father. These alleles can have different variations, resulting in different expression of the trait.
Mendel's Law Of Segregation
Yes - they each carry half the genes needed to make a complete zygote.
It depends. Some genes determine a single trait all by themselves. Some genes work with other genes to make a trait. It takes several separate genes to determine how tall you will be. And then there are other genes that by themselves determine multiple traits. Each gene is the code for a peptide chain. Many of those become proteins.
invisible "factors" - now called genes.
The gametes (sex cells) that combine to form a new organism in sexual reproduction each contain one set of the instructions for the genes of the new organism, that is, one set each for each trait.
Each gene in any organism or virus is a section of DNA that controls a physical trait. There is a gene for every trait in a human that you can think of. Since humans have many traits, it takes multiple genes to cause them.
