He did an experiment with a tall pea plant and a small pea plant. He then went through 2 generations of breeding of these plants and noticed 3 distinct different types of plants. One type was really short, the other was average height, and the final was Tall.
He combined 2 medium sized plants with each other (Tt) and (Tt).
*T = Tall gene.
*t = shortness gene.
Put that into you Punnett square and you will get these answers:
The small plant had a recessive gene (tt).
The medium sized plant had the average set of genes (Tt).
The tall plant also had a recessive gene (TT).
The results were:
1 Small Plant, 2 Medium Plants, and 1 Large Plant.
The recessive allele was hidden by the dominant allele
The recessive allele was hidden by the dominant allele.

novanet:
The recessive allele was hidden by the dominant allele!
Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.
recessive trait
P1 or parental
The first generation of offspring from a cross is called the F1 generation.
When two traits are located on different chromosomes, they assort independently during meiosis. This means that the inheritance of one trait does not influence the inheritance of the other trait, resulting in a random assortment of genetic information. This independent assortment allows for a variety of genetic combinations in the offspring.
They were homozygous.
Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.

When Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
