What is the ratio produced if Tt is crossed with tt?
The ratio produced if Tt is crossed with tt is 1:1 for the genotype and 1:1 for the phenotype. This is because all the offspring will inherit a recessive allele from the tt parent, resulting in all of them having the same genotype and phenotype.
In pea plants the gene for tallness (T) is dominant over the gene for shortness (t). A homozygous dominant pea plant is crossed with a heterozygous pea plant and 200 seeds are produced. Approximately?
When a homozygous dominant pea plant (TT) is crossed with a heterozygous pea plant (Tt), the possible genotypes of the offspring are TT and Tt. This results in a 1:1 ratio of tall (TT and Tt) to short (tt) plants. Therefore, out of 200 seeds produced, approximately 200 seeds will be tall plants (100 TT and 100 Tt) and 0 seeds will be short (tt).
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.

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%
When model crossed true-breeding tall plants with true-breeding short plants all of the offspring were tall because?
Homozygous for tall is TT Homozygous for short is tt All F1 offspring from this cross are Tt which makes them genotypically heterozygous and phenotypically tall.
What is the ratio produced if Tt is crossed with tt?
The ratio produced if Tt is crossed with tt is 1:1 for the genotype and 1:1 for the phenotype. This is because all the offspring will inherit a recessive allele from the tt parent, resulting in all of them having the same genotype and phenotype.
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.
Can a genotype for gray bodied fly be determined?
yes becasue the color changes and it doset mean it's not almost exactly the same as a black or even a purple fly when its crossed with another fly you get (tt) (TT) (tT) AND (Tt)
What are the genotype a of the parents?

Why was 3 1 the ratio in Mendels F2 generation?
In Mendel's F2 generation, the 3:1 ratio observed for dominant to recessive traits arises from the segregation of alleles during gamete formation. When he crossed heterozygous parents (Tt), the resulting offspring can inherit combinations of alleles that produce three dominant phenotype offspring (TT or Tt) and one recessive phenotype offspring (tt). This reflects the principles of Mendelian inheritance, specifically the law of segregation, where each parent contributes one allele for a trait, leading to the 3:1 phenotypic ratio 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%
How many years did they make the tt 225 Yamaha for?
The Yamaha TT-R225 was produced for 5 years, from 1999-2004.
What are the possible offspring outcome if parent 1 Tt crosses with parent 2 tt tt?
Tt, tt -- novanet :)
What are the possible offspring outcomes if parent 1 Tt crosses with parent 2 tt?
The possible offspring outcomes of this cross would be 50% Tt (heterozygous) and 50% tt (homozygous recessive).
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.
When two pea plants with TT genotypes are crossed-bred how many short tt plants will there be in the new generation?
In the offspring generation from crossing two pea plants with TT genotypes, all the offspring will have the genotype Tt. However, all of these offspring will be tall since the tall trait is dominant (T) over the short trait (t). Therefore, there will be no short tt plants in the new generation.
Bobtails in cats are recessive?
