In the P generation a tall plant is crossed with a short plant The probability that an F2 plant will be tall is?
75% there will be TT, Tt, Tt, and tt. tt is going to be short. This means that 3/4 will be tall. 3/4 is 75%
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
What are organisms with the genotype tt is also know as?
two capital or two lowercase letters in the GENOTYPE (ex: TT or tt) it's also called HOMOZYGOUS.
What are the genotype a of the parents?
genotype of the parents - parents will be heterozygous dominant. e.g. take the example of Mendel's pea cross. if parent is heterozygous dominant then the genotype will be Tt and Tt now if you will do a cross then the result you will get is this - Tt X Tt result - TT, Tt, Tt, tt it gives a 3 : 1 ratio i.e. three tall and one dwarf.

What genotype is homozygous?
Total dominant genes or total recessive genes. Therefore, either TT or tt, not Tt.
Pure breeding long stem and pure breeding short stem pee plants are crossed According to Mendel's laws of heridity what will the f2 generation be?
Allele for tall stem (dominant)- T Allele for short stem (recessive)- t The F1 generation would all be tall-stemmed plants with the genotype Tt (heterozygous). The F2 generation would consist of: 25% Tall plants with the genotype TT (homozygous dominant) 50% Tall plants with the genotype Tt (heterozygous) 25% Short plants with the genotype tt (homozygous recessive)
What are the genotypes of the short plants in the P1 and F2 generation?
P1: tt F2: tt
What are the genotypes of the short plants in P1 and F2 Generations?
Because the shot gene in the pea plant is a recessive trait, there is only one possible genotype for it: tt
In the p generation a tall plant was crossed with a short plant. Short plants reappeared in the f2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
In the P generation a tall plant was crossed with a short plant No F1 plants were short Short plants reappeared in the F2 generation because?
A cross between members of the F1 generation (Tt x Tt), results in the genotypic ratio of 1TT:2Tt:1tt genotypes in the F2 generation. Because the tall allele is dominant, the phenotypic ratio would be 3 tall:1 short in the F2 generation.
In the P generation a tall plant is crossed with a short plant The probability that an F2 plant will be tall is?
75% there will be TT, Tt, Tt, and tt. tt is going to be short. This means that 3/4 will be tall. 3/4 is 75%
Why did one of the characteristics for example dwarfness or white flower color disappear in the F1 generation of Mendal's crosses?
Since the F1 generation of crosses is a cross between two pure traits (for example, TT for tall and tt for short/dwarfness), the offspring of the pure parents all have the genotype of Tt: 100% of offspring will be tall. The dwarfness seems to "disappear" because the capital T is dominant, while the lowercase t (for shortness) is recessive. Dominant dominates a recessive trait, so only tallness appears and dwarfness seems to disappear. Additional Info: However, even though the dwarfness seems to "disappear" it is still in the genotype although it does not appear in the F1 generation. In the F2 generation, there will be a 25% chance of the offspring having the trait dwarfness, because the F1 generation is crossed (Tt x Tt).
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
A plant with the genotype TT is called?
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
What genotype is a tall pea plant?
A tall looking pea plant can have a genotype of Tt or TT.
The combination Tt represents what genotype?
A heterozygous genotype
What is genotype called?
Genotype TT is called a homozygous genotype. The TT indicates identical alleles, and the capital letters represent their dominant trait.
