Homozygous dominant would be all Capital letters.
Homozygous recessive would be all lower case letters.
So...in basic color genetics for horses:
A homozygous recessive horse would be aaee
A homozygous dominant horse would be AAEE

The cross between the homozygous tall parent and the honozygous short parent produces only tall offspring what is the term used to describe the allele for shortness?
recessive
What kind of offspring will a homozygous tall plant and a homozygous short plant have?
Presuming tall is a dominant allele (the 2nd parent is heterozygous and "tall" is it's phenotype), then the square would be as follows: Let T be the dominant gene for tall, and thus every genotype containing this (TT, or Tt) would produce a tall plant. Let t be recessive, and in the absence of T (tt) causes a plant to be small. So the homozygous tall parent would be TT, and the heterozygous tall parent would be Tt. So now you just have to cross them. During meiosis, every gamete from the TT genotype would contain a T allele. However, for the Tt genotype, there is equal chance each gamete will contain EITHER a T or a t. So the square would be: xxTxxT TxTTxTT txTtxTt As you can see, 2 out of the 4 offspring have a Tt genotype (heterozygous), so this translates to a 1/2 fraction, or 50%. Ignore the Xs in the table- if i just used spaces then all the letters crunched up on top of each other when i pressed save...it was the best i could do...:S
If a homozygous dominant plant crossed with a homozygous recessive plant what is the genotype and phenotype of their offspring?
If two homozygous plants with contrasting traits are crossed, the expected genotypes for the offspring will be heterozygous. The dominant trait would be expressed, but they'd be carriers for the recessive trait.
In pea plants the allele for tallness is dominant. What are the possible genotypes of a tall pea plant?
the tall plant must be heterozygous
What does it mean if a plant is true breeding?
Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.
What do the letters on the inside of the punnets square stand for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.

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 letters can be used to model Mendels cross of true-breeding tall plants what true-breeding short plants in a Punnett square?
TT for the homozygous tall parent, tt for the homozygous short parent and Tt for the heterozygous offspring.
In certain plants tall is dominant to short If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short?
0 (there is no chance it will be short since tall is dominant over short). Hope this helps! - Biology Student
Paul decides to cross his long haired guinea pig with a short haired guinea pigBoth were homozygous for their traitWhat is the genotypic ratio of the offspring?
The offspring will look more like the mom but they will have mid hair.

What do you get when a heterozygous plant breads with a short plant?
I assume you mean heterozygous dominant tall and short is recessive.T = tall.t = shortTt X tt (called a test cross )1/2 Tt-----------------------heterozygous dominant1/2 tt-----------------homozygous recessive
In pea plants the allele for tallness is dominant. What are the possible genotypes of a tall pea plant?
the tall plant must be heterozygous
