1 will be hemozygous tall TT(25%), 2 will be heterygous tall Tt(50%), and 1 will be dwarf tt.........tatal, 75% will be tall

What is the offspring if you cross two heterozygous Tt tall plants?
You get one homozygous dominant (TT), one homozygous recessive (tt), and two heterozygous (Tt).
Two plants are crossed resulting in offspring with a 3 to1 ratio for a particular trait This suggests?
That the parents were both heterozygous!
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.
If the allele for yellow peas is Y the allele for the contrasting trait green peas is?
y
What generation is always completely heterozygous?
The F1 (first filial) generation is always 100% heterozygous.This is because the F1 generation is defined as the offspring of pure-breeding (homozygous) parents carrying different alleles from each other, e.g. AA x aa. All the offspring must be Aa, in other words heterozygous.
purple petal color in pea plants is dominant to white petal color two heterozygous pea plants are crossed what is the ratio of the offspring with white petals to the number total number of offspring?
3:1 ratio Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio
What is the offspring if you cross two heterozygous Tt tall plants?
You get one homozygous dominant (TT), one homozygous recessive (tt), and two heterozygous (Tt).
What is used to predict the results of offspring between 2 parent plants?
punnett square

Why were all the offsprins purple when gregor menel crossed true breeding purple flowered plants with true breeding white flowered plants?
All the offspring were purple because Mendel was dealing with simple genetic dominance. The purple true breeding parent was homozygous dominant and the true breeding white parent was homozygous recessive. When those two are crossed they create only heterozygous offspring (look up a punnett) and since this is simple dominance those heterozygous will show the phenotype of the dominant allele which is purple.
In pea plants purple flowers are dominant over white flowers. Two plants both heterozygous for the gene that controls flower color are crossed. What percentage of their offspring will have purple flow?

If 240 plant offspring were produced from crossing two heterozygous plants how many would be homozygous?
120 on average or 50%. 25% would be homozygous dominant and 25% would be homozygous recessive. The remaining 50% would be heterozygous.
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.
Varieties of plants in which self- fertilzation produces offspring that are identical to the parents. Are they referred to as hybrids?
Repeatedly Self-fertilized plants are homozygous that is why they are identical to the parents. They are not hybrids. Hybrids are essentially heterozygous due to cross fertilization.
How is sexual reproduction in plants different from sexual reproduction in mammals?
plants are a-sexual reproduction meaning that only one parent is need to make offspring and the offspring is identical to the parent. sexual reproduction is in mammals where two parents are needed to create offspring.
