Two plants are crossed resulting in offspring with a 3 to1 ratio for a particular trait This suggests?
The 3:1 ratio for a particular trait suggests that the trait is determined by a single gene with two alleles. It indicates that one parent is homozygous dominant for the trait, one parent is homozygous recessive, and the offspring are heterozygous.
Suppose that two true breeding pea plants are crossed One of the pea plants always produces yellow pea pods and the other always produces green pea pods If green pea pods are dominant over yellow pe?
If green pea pods are dominant over yellow pea pods, all offspring from the cross will have green pea pods. This is because the dominant trait (green) will mask the recessive trait (yellow) in the heterozygous offspring. The genotype of the offspring will be heterozygous for the pod color trait.
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.
When two pea plants with Tt traits are cross pollinated what offspring will result in what?
The offspring will have a 25% chance of being TT (homozygous dominant), a 50% chance of being Tt (heterozygous), and a 25% chance of being tt (homozygous recessive). This follows Mendel's law of segregation where alleles for a trait separate during gamete formation.
How could the f1 generation of tall offspring produce 3 tall plants and 1 short?
An F1 x F1 cross would be a cross between heterozygous (Tt) parents. The offspring would be 1/4 TT, 1/2 Tt, and 1/4 tt. This would mean that 3/4 of the offspring would be tall, and 1/4 would be short.These offspring would be the F2 generation.

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 used to predict the results of offspring between 2 parent plants?
punnett square
If 240 plant offspring were produced from crossing two heterozygous plants how many would be homozygous?
Out of the 240 offspring, approximately 60 would be homozygous (25% of 240). This is because when two heterozygous plants are crossed (Aa x Aa), the Punnett square shows that 25% of the offspring will be homozygous dominant (AA), 50% will be heterozygous (Aa), and 25% will be homozygous recessive (aa).
When Mendel crossed short tt pea plants with short pea plants the offspring were?
When Mendel crossed short tt pea plants (homozygous recessive) with short pea plants that were heterozygous for height (Tt), the offspring would display a phenotypic ratio of 1 short (tt) to 1 tall (Tt). This is because the short plants (tt) can only contribute recessive alleles, while the heterozygous plants (Tt) can contribute either a dominant (T) or a recessive (t) allele. Therefore, half of the offspring would be tall and half would be short.
In an experiment with pea plants two purple flowered pea plants that are heterozygous for the alleles for flower color are crossed The results are offspring with purple flowers 25 offspring with w?
they are fine; expected ratios might not been seen simply due to chance
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?

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 will the colors of the offspring of a heterozygous yellow and green pea plant?
In pea plants, the yellow color (Y) is typically dominant over the green color (y). If a heterozygous yellow pea plant (Yy) is crossed with a green pea plant (yy), the possible genotypes of the offspring would be 50% heterozygous yellow (Yy) and 50% homozygous green (yy). Therefore, the offspring would exhibit a 50% chance of being yellow and a 50% chance of being green.
What is the possibility that two heterozygous parents would have an offspring that produced round seeds?
In pea plants, the round seed trait (R) is dominant over the wrinkled seed trait (r). If both parents are heterozygous (Rr), the possible offspring genotypes are RR, Rr, and rr, with a 75% chance of producing round seeds (RR or Rr) and a 25% chance of producing wrinkled seeds (rr). Therefore, there is a 75% possibility that two heterozygous parents would have an offspring that produces round seeds.

The 3:1 ratio for a particular trait suggests that the trait is determined by a single gene with two alleles. It indicates that one parent is homozygous dominant for the trait, one parent is homozygous recessive, and the offspring are heterozygous.
Suppose that two true breeding pea plants are crossed One of the pea plants always produces yellow pea pods and the other always produces green pea pods If green pea pods are dominant over yellow pe?
If green pea pods are dominant over yellow pea pods, all offspring from the cross will have green pea pods. This is because the dominant trait (green) will mask the recessive trait (yellow) in the heterozygous offspring. The genotype of the offspring will be heterozygous for the pod color trait.
If you made a Punnett square showing Gregor Mendels cross between true breeding short plsntd the square would show that the offspring had what?
The Punnett square would show that all offspring would be heterozygous for the trait, meaning they would have one allele for tall plants and one allele for short plants. This would result in all offspring being tall plants phenotypically, but carrying the allele for short plants.
