Is short or tall gene dominant?
A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant.
What is the genotype of the pink parent?
The genotype of the pure-breeding pink parent must be bbWW. In a certain species of plant, flowers occur in three colors: blue, pink, and white.
What is the term when a cross of red and white parents produces pink offspring?
Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring. An example is a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring.
What genotype would create a tall offspring?
The offspring with the genotypes TT and Tt will have a phenotype of tall; the offspring with the genotype of tt will have a phenotype of short. If the two alleles are the same (TT or tt), the genotype is considered purebred. If the two alleles are different (Tt), the genotype is considered hybrid.
Can short parents have a tall child?
It is possible to have a tall child from relatively short parents. Whilst genetics play a major role, other modifiable factors can help increase such a child's height.
Can you be tall if your parents are short?
Chances are you'll be around the same height as your parents. If one parent is tall and one short, then you're likely to end up somewhere in between. But you could be taller or shorter, too. ... That's because your height is determined by your genes — the complicated code of instructions that you inherit from your parents.
What is the red genotype?
When ever the R gene is present in the genotype of a plant, the flower color is always red. The mutant form of this gene, which is recessive, is often written r. Plants with the genotype RR or Rr have red flowers. Plants with the genotype rr have white flowers.
When pink-flowered plants were crossed they produced offspring with red pink and white flowers in a ratio of 1 2 1 This is an example of?
When pink-flowered plants were crossed they produced offspring with red, pink, and white flowers in a ratio of 1:2:1. This is an example of: a. variegation.
What is the probability of two pink flowers producing a red flower?
In this case, if two pink-flowered pea plants are mated ("crossed" is a better word than "mated" for plants), the offspring plants are independent of each other, and each has red flowers with probability 1/4, pink flowers with probability 1/2, and white flowers with probability 1/4.
Are pink flowers incomplete dominance?
The pink flower color trait, which is an example of incomplete dominance, occurs in nature, such as those found in pink-flower-bearing angiosperms. Turns out the dominant allele is not expressed “completely” as shown in Figures 1 and 2 – incomplete dominance (Punnett square).
What is the resulting color if you crossed red rose with white rose?
Understanding Codominance And Incomplete Dominance : Example Question #1. A plant with red flowers is crossed with a plant with white flowers. The resulting offspring have pink flowers.
Why does crossing true breeding red and white snapdragons result in pink offspring?
Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time. ... Red + white = pink.
Is TT tall or short?
The "TT" and "Tt" crosses both have at least one "T" allele, so they are tall plants. However, the last cross "tt" doesn't have any "T" alleles and is short, because it is homozygous recessive . Since 1 out of 4 pea plants are short, or 1/4, the probability of a short pea plant from a heterozygous cross is 25%.
Is red hair genotype or phenotype?
Red hair is the null phenotype of MC1R.
