In pea plants, yellow seeds are dominant to green.
What color is dominant in peas?
yellow
For the seed colour, yellow is the dominant trait and green is recessive while for the fruit (pod) colour, green is dominant and yellow is recessive. Q. A monohybrid cross is conducted in which a pea plant that produces yellow coloured seeds was crossed with a pea plant that produces green coloured seeds.
Is green or yellow dominant in peas?
Yellow peas (I) are dominant to green peas (i). The I gene is on chromosome 1. In all pea plants, immature peas are green.
Is yellow seed color dominant or recessive?
dominant
Seed color is governed by a single gene with two alleles. The yellow-seed allele is dominant and the green-seed allele is recessive. When true-breeding plants were cross-fertilized, in which one parent had yellow seeds and one had green seeds, all of the F1 hybrid offspring had yellow seeds.
Is yellow seed color dominant?
The correct option is B 1 : 1
In pea plants, yellow seeds are dominant to green.
Which trait is dominant in pea plants?
So, the correct answer is ‘green pod‘.
Is green pea dominant or recessive?
Green pea seeds ( yy ) are recessive to yellow pea seeds ( YY )in the given cross. When two heterozygous pea plants ( Yy ) are crossed the offsprings will be 75% ( 3/4 ) dominant and 25% (1/4) recessive according to punnet square i.e, YY, Yy and Yy. So, if 1000 individuals are produced than 750 will be dominant.
What are the 7 characteristics of pea plants?
On the next screen, he reveals that there are seven different traits:
- Pea shape (round or wrinkled)
- Pea color (green or yellow)
- Pod shape (constricted or inflated)
- Pod color (green or yellow)
- Flower color (purple or white)
- Plant size (tall or dwarf)
- Position of flowers (axial or terminal)
Is green color dominant?
Green and red colour of seeds are the recessive and dominant traits respectively.
What is the probability of getting yellow pea plants?
Since the Y (yellow) allele is dominant over the G (green) allele for pea plants, 100% of the YG offspring will have a yellow phenotype, as Mendel observed in his breeding experiments.
What colour is pea?
Pea seeds naturally appear in a variety of colours from shades of yellow to dark purples, but it is the vibrant green pea that has been exploited widely for food. However pea seeds can lose their green colour at or after seed maturity.
What is the genotype of the yellow colored parent?
The dominant seed color is yellow; therefore, the parental genotypes were YY for the plants with yellow seeds and yy for the plants with green seeds.
What are the possible genotypes of the pea plants?
The possible genotypes are PpYY, PpYy, ppYY, and ppYy. The former two genotypes would result in plants with purple flowers and yellow peas, while the latter two genotypes would result in plants with white flowers with yellow peas, for a 1:1 ratio of each phenotype.
What are the alleles for the green pea seed?
In the case of Mendel’s peas, there are two different versions, or alleles, for seed color: yellow (Y) and green (y). Every plant will have two copies of each gene.
Which of the peas traits yellow or green is dominant explain your answer?
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!
Is wrinkled or round dominant?
In garden pea, round shape of seeds is dominant over wrinkled shape. A pea plant heterozygous for round shape of seed is selfed and 1600 seeds produced during the cross are subsequently germinated.
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 one is not a dominant character in pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
Which traits of garden peas are recessive?
- Wrinkled seeds – a recessive trait.
- Tall stem – a dominant trait.
- Round seeds – a dominant trait.
- Coloured seed coat – a dominant trait.
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 dominant shape of a pea pod?
Full pod shape
Full pod shape is completely dominant to constricted peapod shape. Pea plant size is also controlled by one gene-two allele system with tall size being completely dominant to dwarf size. Given a plant was heterozygous for pod shape and homozygous recessive for plant size: a.
