What did Mendel's experiments show about blending inheritance?
Blending inheritance was one hypothesis for how traits were passed from one generation to the next. The idea was that if both parents had different traits for a particular character, then the offspring would exhibit a blend of the two traits. For example, if the character in question is flower petal color, and one parent had white flowers and the other had red flowers, the hypothesis of blending inheritance would predict the offspring would have pink flowers, a blend of the two parent traits. In fact, if you cross red and white flowered plants, you do get a pink flower. However, Mendel was able to show that the inheritance of flower color was particulate, not blending, by going one step further and crossing two pink flowered parents. He found the offspring had a ratio of 1:2:1 for red:pink:white, so the granparents' traits were reappearing. This "skipping of generations" was classically Mendelian: the alleles for red and white were both contained in the pink flowers, so that when they were crossed, they were able to be seen in the offspring. In this case, consider that red flowers have the genotype RR (homozygous for R allele), white flowers have the genotype WW (homozygous for the W allele), and pink flowers have the genotype RW (heterozygous), where R and W are two different alleles for flower color. When red (RR) and white (WW) are crossed, the offspring can only get the R allele from the red parent and the W allele from the white parent, so they are all heterozygous (RW), resulting in a pink color. When two pinks are crossed (RW x RW), then each parent can give either a red allele (R) or a white allele (W) to the offspring, resulting in the following equally likely possible combinations: RW, RR, WW, and WR. Since WR and RW are the same (pink), the expected ratio of offspring is 1 RR: 2 RW: 1 WW. This is considered an example of particulate inheritance, not blending inheritance, because the alleles (particles) are being preserved throughout the generations; it is simply the combinations of alleles that give the appearance of a blending inheritance mechanism when red and white are crossed to produce pink. In classical genetics, the first cross between red (RR) and white (WW) was considered the P (parental) generation. The hybrid offspring produced (RW) were considered the first filial generation (F1). Crossing two F1's shows that the inheritance is particulate, by looking at the 1:2:1 ratio in the F2 generation (1 red: 2 pink: 1 white). Mendel was able to deduce the theory of particulate inheritance by carefully following the generations from P to F1 to F2.
Explain the difference between intermediate inheritance and codominance?
In codominance, neither phenotype is recessive. Instead, the heterozygous individual expresses bothphenotypes. Intermediate inheritance is when neither allele is dominant to another, but a mixture is produced in the 2 alleles present. A mixed phenotype is given that is between the two parents phenotype .e.g Red flowers (RR) crossed with white flowers (WW) produces pink flowers (RW).
Mendel saw purple flowers in the F generation but both purple and white flowers in the F How did this help him see that traits are inherited as discrete units?
Because the traits weren't blended resulting in pink flowers. They were still purple and white.
When the phenotype of two alleles are blended what are they called?
The blending of the phenotype of the parents in the offspring is known as incomplete. colors of flowers can show incomplete dominance if a red flower is crossed with a white flower and their offspring are pink.
Why do flowers have different color petals?
photosynthesis The coloration in petals is due the presence of chromoplasts in the cells of the petals. In different flowers chromoplasts differ in the nature of their coloration. Therefore, different colors are seen in the petals of different flowers.

Do flowers come with their colors?
Yes, flower colour is an inherited genetic trait. Although some flowers may start off a specific colour and change colour as the flower matures

Did people put flowers by Mozart's tomb?
No. Mozart was buried for reasons never satisfactorily explained in a pauper's grave the location of which is not known.
What kind of flowers would a witch use after taking over a recently deceased persons home?
There is no specific answer to this, If the witch in question has favourite flowers those may well feature prominently in the gardens of the house. If he/she inherited the house from the previous owner she may chose to put in a flower or flowers that remind her of the deceased. If he/she does not have a green thumb then flowers may not appear at all.
When the phenotype of two alleles are blended what are they called?
The blending of the phenotype of the parents in the offspring is known as incomplete. colors of flowers can show incomplete dominance if a red flower is crossed with a white flower and their offspring are pink.
Mendel found purple flowers in the f1 generation both prple and white flowers in the f1 generation how did this help him see that traits are inherited as discrete units?
Because he grasped that there had to be an independant "factor" as he called genes and that even if they don't always manifest they are still there and intact.
Why do you think the Greeks created the myth of Demeter and Persephone?
It explained the seasons. After Hades stole persephone and made her his bride, he kept her in the underworld and in that time, Demeter was depressed so she gave the Greeks bad harvest, and with Persephone being in the underworld, no flowers could grow. This explained winter. During summer and spring, demeter and Persephone were re-united, so flowers bloomed on earth again, and the people's crops were revived.
