Green (Y) is dominant over yellow (y) in peas, and the smooth allele (W) is dominant over wrinkled (w). Which of the following crosses produces green and smooth peas?
Are yellow or green peas dominant?
Yellow peas (I) are dominant to green peas (i). The I gene is on chromosome 1. In all pea plants, immature peas are green.
Which color of pea is dominant?
Since yellow is dominant to green, all of the offspring were yellow. The green phenotype had disappeared. I allowed the yellow pea plants to self- fertilize to see what the second generation would look like. Some of the second generation offspring were green!
Which pea trait is dominant?
Green pod color
Green pod color is dominant and yellow is recessive. The shape of the pod has two traits – inflated and constricted.
Is green dominant in pea plants?
For gene 2, there are two possibilities, green or blue. Green is dominant over blue. Green eyes can be GG, or Gb, while blue eyes are bb. Brown is dominant over green, so if you have a B version of gene 1 and a G version of gene 2, you will have brown eyes.
Why yellow is dominant in pea plant?
And that the genes can come in different versions. So all of the offspring got a Y from the yellow plant and a y from the green one. They were all Yy. Since they were all yellow, this means that yellow is dominant over green.
Is green color dominant?
Green and red colour of seeds are the recessive and dominant traits respectively.
Why are peas green not yellow?
Chlorophyll is broken down by proteins encoded by so-called stay-green genes, and the decline of chlorophyll levels causes yellowing of the peas. Many plants that we eat have been selected for mutations in these genes, which thus cause retention of greenness.
What is the recessive trait of pea plant?
The axial flower position was recessive to terminal position. Green seed and wrinkled seeds were recessive to yellow and round seeds; yellow, constricted pods were recessive to green and full pods.
Which of these is not a dominant trait of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
Is yellow pod recessive?
In pea plants, yellow pod color is recessive and green pod color is dominant. A heterozygous plant produced offspring with a plant that is homozygous dominant for the trait.
What is recessive and dominant trait?
Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive. If one of the alleles is dominant, then the associated characteristic is less likely to manifest.
What is dominant or recessive?
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
Is green dominant or recessive?
The allele genes come in the form of brown, blue, or green, with brown being dominant, followed by green, and blue being the least dominant or what is called recessive.
Which Colour is dominant?
Primary colors, though, are the most dominant (followed by secondary, then tertiary colors) because red, blue and yellow can’t be created by mixing other colors. The eye also perceives dominant colors in the foreground of images and documents.
Why green eyes are dominant?
The allele for brown eyes is the most dominant allele and is always dominant over the other two alleles and the allele for green eyes is always dominant over the allele for blue eyes, which is always recessive.
Why are peas green?
It is now known that the green colour of mature pea seeds is due to the abundance of chlorophyll (a central component of the plant photosynthetic machinery).
When pea plant with yellow seeds crossed with green seeds What would be the probability of green seeds in the F₁ generation?
The cross between heterozygous yellow seeded plant and green seeded plant will produce 50% yellow seeded plants and 50% green seeded plants. Hence, option A is the correct answer.
How did the probabilities of yellow seeds and green seeds compare with each other?
When counting all four possible outcomes, there is a 3 in 4 probability of offspring having the yellow phenotype and a 1 in 4 probability of offspring having the green phenotype.
Is Round green a dominant?
In pea plants, Round (R) and Yellow (Y) features of seeds are dominant over wrinkled (r) and green (y) features.
Which one of the two is dominant yellow colour of seed coat or its green colour?
Video Solution: The gene for yellow seed coat in peas is dominant to its allele,green .
