What will be the ratio produced if Tt is crossed with tt?

Answer: 50% Tall : 50% Short


What is the importance of a 9331 ratio in a monohybrid cross?

The phenotypic ratio expected from a monohybrid cross between heterozygotes is 3:1 (assuming complete dominance), with the genotypic ratio being 1:2:1. So, using tall = T, short = t and R = red, r = white as an example. A monohybrid cross of Tt X Tt would be expected to produce 3 tall plants and 1 short plant (phenotypic ratio 3:1), which would be 1 TT, 2 Tt and 1 tt (genotypic ratio 1:2:1). A dihybrid cross of heterozygotes is expected to produce a phenotypic ratio of 9:3:3:1. So the cross of TtRr X TtRr would be epected to have: 9 tall red, 3 tall white, 3 short red and 1 short white (phenotypic ratio) This is because each parent has 4 possible combinations of gametes (TR, Tr, tR and tr). There are therefore 16 combinations of gametes, providing a 9:3:3:1 phenotypic ratio. Both of these are probably best visualised using a punnett square (see link below).


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 is the ratio produced if Tt is crossed with tt?

1/2 Tall 1/2 Short.


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 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.

Two individuals heterozygous for a single trait have children what is the expected phenotypic ratio of the possible offspring?

Let T=trait (dominant) Let t= trait (recessive) Father has Tt and mother also has Tt The possible combinations for offspring are: TT Tt Tt and tt Therefore There is a 3/4 change of the offspring having the dominant trait and a 1/4 Chance of the offspring having the recessive trait It should also be noted that there is a 1/4 chance of the offspring carrying two dominant genes meaning that any of their children will also share the dominant trait


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.


What are the possible offspring outcomes if parent 1 Tt crosses with parent 2 tt?

Tt, tt -- novanet :)

When two pea plants with Tt traits are cross pollinated what offspring will result in what?

If the two parent pea plants have Tt traits, they will create TT, Tt, Tt, tt. 1 TT - homozygous dominant, 2 Tt - heterozygous, and 1 tt - homozygous recessive.


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.
