dominant.
Mendel discovered that yellow peas are dominant over green peas. Using G and g to represent the dominant and recessive alleles, respectively, cross a homozygous yellow pea with a green pea and then select any two of their offspring and cross them.
Is yellow dominant or recessive in pea plants?
Yellow is dominant and green is recessive. A true-breeding yellow pea plant is crossed with a homozygous green pea plant. What genotypes and phenotypes appear in the F1 generation?
Are yellow pea seeds dominant?
In pea plants, yellow seeds are dominant to green seeds.
Which color of pea is dominant?
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.
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.
Why are yellow peas dominant?
Since they were all yellow, this means that yellow is dominant over green. Having one Y is enough to mask the y and cause the peas to be yellow. The one yellow dominates the recessive green.
What more dominant yellow or green?
Since yellow is dominant to green, all of the offspring were yellow.
What is the chance that yellow pea is homozygous for the dominant allele?
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.
Why are peas green not yellow?
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).
What happened when Mendel let the yellow peas self fertilize?
Mendel instead observed that all the offspring of the cross were tall, and that when they self-fertilized, they produced tall and short plants in a ratio of 3:1.
Are wrinkled peas dominant or recessive?
The shape of the pea seeds is controlled by two alleles. S is dominant alleles and stands for smooth and s is recessive allele and stands for wrinkled.
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.
Which of the following is not a dominant character of pea plant?
So, the correct option is ‘Pod colour – Yellow‘.
What is the recessive trait of pea plants?
Green seed and wrinkled seeds were recessive to yellow and round seeds; yellow, constricted pods were recessive to green and full pods. Dwarf stem and white flowers were recessive to tall stem and violet flowers. Thus, the correct answer is option C.
Do pea plants have dominant traits?
Mendel cross-bred peas with 7 pairs of pure-bred traits. First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits.
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.
What genetic fact do you know about any yellow seed pea plant?
In cross-pollinating plants that either produce yellow or green pea seeds exclusively, Mendel found that the first offspring generation (f1) always has yellow seeds. However, the following generation (f2) consistently has a 3:1 ratio of yellow to green.
Are white flowers dominant or recessive?
Answer and Explanation: According to Mendelian inheritance, the presence of even one dominant allele in the genotype will result in the expression of a dominant allele. The white colour of the flower is a recessive trait.
Is green pod color dominant or recessive?
dominant
Green pod colour is dominant over yellow pod colour in pea plants.
What colors are 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. Given this information, you can determine what eye colors are dominant in the parents.
Is blue dominant to yellow?
Yellow body color is dominant to blue.
