A recessive allele means that the gene codes for an nonfunctional enzyme. If the pea plant has 2 recessive allele for the green pea gene, that means that the green pigment will not be deposited on the peas, as the enzyme is nonfunctional. The result would be yellow coloured peas.
If the pea plant has one recessive and one dominant allele for the green pea pigment, then it will result in a half functional enzyme, which is sufficient for the green pigment to be deposited.
you would get a pea that show which trait is more dominant
It will produce green peas, if it doesn't also have a dominant allele for yellow peas.

the genotype can only be tt
green peas if it does not also have a dominant allele for yellow peas.
Yellow pods are a recessive trait and for this type of trait to show in the phenotype, both alleles have to be recessive. If there was a recessive allele (yellow) and a dominant allele(green) as it shows in hybrid pods, then the dominant allele would be the one shown and the pod would be green.
he breeded the f1 plants with a recessive homozygous plant and if the offspring (f2) showed the recessive allele, then the recessive allele is still present in the f1 plant
The traits inherited depends upon the alleles that have been passed on from the father and mother.The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed.For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele .TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait.In this case the dominant allele masks the recessive allele and the pea plant is still tall.tt - when there are two recessive alleles the pea plant will express the recessive trait and the pea plant is short.For a recessive trait to show up there should be a pair of recessive alleles.
A cross between a plant of unknown genotype and one that is known to be homozygous recessive is called a test cross because the recessive homozygote testswhether there are any recessive alleles in the unknown. Because the recessive homozygote will contribute an allele for the recessive characteristic to each offspring, the second allele (from the unknown genotype) will determine the offspring's phenotype.

if the pea plant has 2 recessive alleles then the plant is gonna come out short.but if it has 1 recessive and one dominant allele then the plant turns out tall, because the dominant allele can be present without the recessive allele.

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 alleleThe 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.Novanet Swagnovanet:The recessive allele was hidden by the dominant allele!
