What will be the ratio produced if Tt is crossed with tt?
Answer: 50% Tall : 50% Short
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).
What is the ratio produced if Tt is crossed with tt?
1/2 Tall 1/2 Short.
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.
Mendel crossed pea plants that produced inflated pods with those that produced constricted pods. From a total of 3325 F2 seeds 2474 were inflated and 851 were constricted. Using the symbols P for gene?
Using the symbols "P" and "p" for genes, symbolize the parental cross, the F1 cross. and the F2

Who was British Farmer who crossed purple flowering pea plants with white flowering pea plants?

If A red flowered plant is crossed with a white flowered plant all of the offspring is pink what inheritance pattern is this?
Incomplete dominance: for example is seen in hair type inheritance. Curly hair type (CC) is dominant to straight hair type (cc). An individual who is heterozygous for this trait will have wavy hair (Cc).
What is Mendel known for?
He is known as the father of genetics. He crossed pea plants to determine the patterns of inheritance for certain traits.
Which inheritance pattern results when parents are crossed for pure traits and the resulting offspring have traits that appear to blend?
co-dominance
