In Purple flower color dominant over white flower color peas. Suppose two white flowered pea plants are crossed and produce 1000 offspring. How many of those offspring would you expect to have whit?
1000
What happened when Mendel crossed a purple flowered pea plant with a white flowered plant?
Mendel observed that all the offspring had purple flowers, showing that purple is dominant over white in pea plants. He discovered the principle of dominance and the concept of alleles.
Describe the offspring of a true breeding white flowering plant?
The offspring of a true breeding white flowering plant will also display white flowers because it carries two copies of the white flower gene. These offspring will be homozygous for the white flower trait and will consistently produce white flowers when they reproduce.
What happens when a red flowered plant with incomplete dominance is crossed with a pink flowered plant which is the offspring of the crossing of a white flowered plant and a red flowered plant which has incomplete dominance?
The crossing of a red flowered plant and a white flowered plant produces all the offspring with pink flowers. This cross illustrates red and white exhibit incomplete dominance. ... With the result, the heterozygous offspring will be phenotypically and genotypically different from either of the homozygous parent.
When there is incomplete dominates what happens?
If there is incomplete dominance, the offspring will have an intermediate of phenotype. For example, if you mate a homozygous white flowered snapdragon plant with a homozygous red flowered snapdragon plant, you will get pink flowered offspring.
A cross between homozygous purple-flowered and homozygous white-flowered pea plants results in offspring with purple flowers This demonstrates?
A homozygous purple flower and a homozygous white flower having offspring that are purple is an example of dominance. Traits that yield to other traits is referred to as recessive. So in this case Purple was the dominant trait and White was the recessive trait.
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.
What is the phenotype of a heterozygous four o'clock flowers?
White-flowered, red-flowered, and pink-flowered.
What is an example of incomplete doiminance?
Incomplete dominance is a genetic phenomenon where neither allele is completely dominant over the other, resulting in a phenotype that is a blending of both traits. A classic example is found in snapdragon flowers, where crossing a red-flowered plant (RR) with a white-flowered plant (WW) produces pink-flowered offspring (RW). This pink color demonstrates the intermediate phenotype characteristic of incomplete dominance.

What is an example of phenotype blending?
Phenotype blending is illustrated in the inheritance of flower color in certain plants, such as snapdragons. When red-flowered snapdragons are crossed with white-flowered ones, the resulting offspring often exhibit a pink phenotype, demonstrating a mix of the parental traits. This blending occurs because neither color is completely dominant, leading to an intermediate expression in the offspring. This concept is a key feature of incomplete dominance in genetics.
Are pea plants self fertilize?
In F 2 , he got 3:1 ratio in tall and dwarf pea plants .Phenotype - All TallTT x TtTT (75%) TallTt (25%) Tall
When Gregor Mendel crossed true breeding purple flowered plants with true breeding white flowered plants all the offspring were purple because?
PP X ww or Pw X ww Because all Purple flower plants are dominant and express the color purple. This can be seen in a homozygous cross, or a heterozygous cross, ( shown above ) White plants, to breed true, must be in homozygous condition.
A cross between homozygous purple flowered and homozygous white flowered pea plants results in offspring with purple flowers This demonstrates?
The principle of dominance.The gene for purple flowers is dominant, while the gene for white flowers is recessive. We know this because both flowers are homozygous, meaning their genes are the same. The genotype of Penelope (the purple flower) is PP, or purple purple. The genotype of Walter (the white flower) is pp, or white white. Because of this, if the gene for white petals was dominant, all the flower offspring would display white petals. If the genes were codominant, the flower offspring would be lavender, an even mix between the white and purple phenotypes.The Punnet square for this example (if you are a visual person) looks like this:......................Walter........................p | p....................___ | ___................P | Pp | Pp |Penelope .....________................P | Pp | Pp |...................|___|___ |You can clearly see that all the offspring are heterozygous, yet because they all share Penelope's phenotype, it is quite obvious that, again, the gene for purple flowers is dominant.
If out of 100 offspring 74 are purple flowered and 26 are white what were the probable genotypes and phenotypes of the parents?
The observed ratio of 74 purple-flowered to 26 white-flowered offspring suggests a typical Mendelian inheritance pattern, likely indicating that purple is dominant over white. The 3:1 ratio (approximately) points to the parents being heterozygous for the purple trait (Pp) and homozygous recessive for the white trait (pp). Therefore, the probable genotypes of the parents are Pp (purple) and pp (white), resulting in the phenotypes of 74 purple-flowered and 26 white-flowered offspring.
A mating between a purebred purple flowered pea plant and a purebred white flowered pea plant would produce what?
A mating between a purebred purple flowered pea plant (which is typically dominant) and a purebred white flowered pea plant (which is recessive) would produce offspring that all exhibit the dominant trait. Therefore, the resulting offspring would all have purple flowers. This is based on Mendelian genetics, where the dominant allele masks the expression of the recessive allele.
