You are looking at four tall pea plants What are their phenotypes and genotypes?
tall; Tt or TT
For each phenotype give the genotypes that are possoble for Patrick?
Tall=TT Short=tt
What are the genotypes of the short plants in the P1 and F2 generation?
P1: tt F2: tt
Why isn't it possible to have more genotypes than phenotypes?
I think you have the question backwards, "Why isn't it possible to have more phenotypes than genotypes?" There are always more or an equal number of genotypes relative to phenotypes. The phenotype for a simple dominant/recessive interaction (for example) T for tall and t for short where TT is tall, Tt is tall and tt is short has three genotypes and two phenotypes. If T and t are co-dominant then TT would be tall, Tt would be intermediate and tt would be short. (Three phenotypes and three genotypes.)
In pea plants the allele for a tallness is dominant what are the possible genotypes of a tall pea plant?
TT or Tt
What are the genotypes of Alice of Hesse and Leopold Duke of Albany?
The genotype of Alice of Hesse is Tt and Leopold is tt.
What is the phenotypic ratio for Genotype TT Tt Tt tt?
3 : 1 ( since the given situation of segregating genotypes TT Tt Tt tt comes under monohybrid genetic combination, it will show 3 tall plants and 1 dwarf plant because gene T is dominant over t.
A recessive allele t is responsible for a condition called distonia a man who has this condition marries a woman who doesnt one of their four children has the conditon what are the pssible genotypes?
Firstly, if the condition is recessive, both the man and the child with the condition must have the genotype tt. The mother must have the genotype Tt. This is because if she had TT, all of the children would be Tt and not have the condition. If she were tt, she would have the condition as well. Therefore if the father has tt and the mother has Tt, the other 3 children who do not have the condition must all have the genotype Tt. So: Mother - Tt Father - tt Affected child - tt Other children - Tt
What must be the genotypes of the parent plant?
both must be tt
What must be the genotypes of the parent plants?
both must be tt
To produce pea plants that only display the recessive phenotype of a trait what must be the genotypes of the parent plants?
both must be tt
What are the possible genotypes of pea plants?
Either TT or Tt, where T stands for dominant gene for tallness and t for recessive gene.
