MONOHYBRID HELP (for above activity)
Monohybrid problems deal with only 1 trait. In this example, that trait is "height". Dominant genes are represented by capital letters while recessive genes are represented by small letters.
So a capital "T" represents the gene that causes tallness (dominant trait) and a small "t" represents the gene that causes dwarfness (recessive trait).
A dominant gene masks the presence of a recessive gene so that even if the recessive gene is present, it isn't always noticeable. So, "Tt" would cause tallness even though the "t" gene is present. This is called complete dominance.
For some traits (such as tallness), it is assumed that only 2 genes code for the trait. That's why we use combinations like "TT", "Tt" or "tt". This is the diploid condition where one gene (say "T") is located on one homologous chromosome and the other gene (say "t") is located on the other homologous chromosome.
When an organism produces sex cells (gametes) so that it can mate, those gametes receive only 1 of the 2 genes for the trait (ie. the haploid condition). This is why single genes are placed in the outer spaces of the Punnett square. When those genes combine ( when organisms mate), the diploid state is re-created and that's why the inner spaces of the Punnett square each have 2 genes.
Having 2 of the same genes (ie. "TT" or "tt") is referred to as homozygous whereas having 2 different forms of the gene (ie. "Tt") is referred to as heterozygous.
