Mendel discovered that by crossing true-breeding white flower and true-breeding purple flower plants, the result was a
hybrid offspring
. Rather than being a mix of the two colors, the offspring was purple flowered.
When Mendel crossed a true-breeding purple flowered pea plant with a true-breeding white flowered pea plant?
Mendel noted that hybridizing true-breeding (P generation) plants gave rise to an F
1
generation that showed only one trait of a characteristic. For example, a true-breeding purple-flowering plant crossed with a true-breeding white-flowering plant always gave rise to
purple-flowered
hybrid plants.
What happened when Mendel crossed true-breeding purple flowers with white flowers?
What was the result when Mendel crossed true-breeding purple flowers with white flowers?
All the offspring were purple.
When Mendel crossed true-breeding purple plants with true-breeding white plants all the offspring were purple because?
| Question Answer | Mendel crossed true-breeding purple-flowered plants with true-breeding white-flowered plants. All the offspring were purple because: the allele for purple-flowered plants is dominant . | Homozygous Organisms that have two identical alleles for a trait. |

What happens when a true breeding purple flower pea plant is crossed with a true breeding white flower pea plant?
You cross a “true-breeding” purple flowered, tall pea plant (PPTT) with a “true-breeding” white flowered, dwarf pea plant (pptt) and you
get 100% purple, tall pea plants in your F1 generation
. Both parent plants are “true breeding” and all of the F1 offspring have purple flowers and round seeds.
Could two plants with purple flowers produce a plant with white flowers?
Can two plants with purple flowers produce offspring with white flowers?
Yes
, if both parents are heterozygous for the trait.
When Gregor Mendel crossed pure breeding purple flowers with pure breeding white flowers What did he notice in the F1 offspring?
When Mendel crossed a true-breeding purple-flowered
pea plant
with a true-breeding white-flowered pea plant, he observed that all of the F1 offspring had purple flowers. When these F1 plants were selfed, he found 3/4 were purple and 1/4 were white.
What does it mean for a plant to be true-breeding for purple flower color?
What does true breeding mean? if you cross a true breeding purple flowered plant with itself (
something possible; self-fertilization
) it will only produce purple flowered plants, it breeds “true” to the purple flower characteristic.
What happens when you cross two true-breeding plants?
When true-breeding, or homozygous, individuals that differ for a certain trait are crossed,
all of the offspring will be heterozygous for that trait
. If the traits are inherited as dominant and recessive, the F
1
offspring will all exhibit the same phenotype as the parent homozygous for the dominant trait.
When Mendel set up a parental cross between true-breeding purple?
Mendel noted that hybridizing true-breeding (P generation) plants gave rise to an
F
1
generation
that showed only one trait of a characteristic. For example, a true-breeding purple-flowering plant crossed with a true-breeding white-flowering plant always gave rise to purple-flowered hybrid plants.
When Mendel crossed a true-breeding tall plant with a true-breeding short plant the F1 offspring were?
| Question Answer | When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, all of the offspring were tall because the allele for tall plants is dominany | The principles of probability can be used to predict the traits of the offspring produced by genetic crosses |
|---|
Are purple flowers dominant or recessive?
| Trait Dominant Expression Recessive Expression | Color of seed albumen (Y) Yellow Green | Color of flower (P) Purple White | Form of ripe pods (I) Inflated Constricted | Color of unripe pods (G) Green Yellow |

Why did all of Mendel's F1 generation pea plants have purple flowers?
Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color. As shown in the Figure below, Mendel cross-pollinated purple- and white-flowered parent plants. … The F1 generation results
from cross-pollination of two parent (P) plants
, and contained all purple flowers.
When Mendel cross-pollinated purple flowers and white-flowered parent plants What did he observe?
the law of segregation and the law of independent assortment. When Mendel cross-pollinated purple- and white-flowered parent plants, what did he observe?
The F2 generation was 75% purple-flowered plants and 25% white-flowered plants
. that some of the F2 had green, round pods and some had yellow, wrinkled pods.
Why did the F1 generation showed all flowers to be purple rather than a mix of white and purple flowers?
Mendel discovered that by crossing true-breeding white flower and true-breeding purple flower plants, the result was
a hybrid offspring
. Rather than being a mix of the two colors, the offspring was purple flowered. … The resulting hybrids in the F1 generation all had violet flowers.
Could a plant with purple flowers and one with white flowers produce purple flowered plants could they produce plants with white flowers explain for both questions?
Checking the probability of fusion between the gametes produced by two plants crossed using Punnet Square method, it is seen that
75% plants will have
at least one dominant allele (P) and thus will bear purple flowers. … These plants will bear white flowers.
