Mendel demonstrated that the green seed trait was not lost but masked by conducting experiments with pea plants. He observed that when he crossed plants with yellow seeds (dominant) and green seeds (recessive), the first generation (F1) all produced yellow seeds. However, when he self-pollinated the F1 generation, the second generation (F2) displayed both yellow and green seeds in a 3:1 ratio, revealing that the green seed trait had been carried over and was simply hidden in the F1 generation. This led Mendel to conclude that traits can be dominant or recessive, with recessive traits re-emerging in subsequent generations.

How did Mendel show that the green-seed trait did not disappear but was only masked?
Mendel demonstrated that the green-seed trait did not disappear but was simply masked by conducting crossbreeding experiments with pea plants. He observed that when he crossed purebred yellow-seed plants with purebred green-seed plants, the first generation (F1) exhibited only yellow seeds. However, when he allowed the F1 generation to self-pollinate, the second generation (F2) revealed a 3:1 ratio of yellow to green seeds, indicating that the green-seed trait was still present but hidden in the F1 generation. This suggested the concept of dominance, where the yellow trait masked the expression of the green trait.
What is the kind of trait that seemed to vanish in the offspring produces in Mendel's first experiment?
Mendel's experiments showed the characteristics of genes that express complete dominance--that is, traits where one allele is completely dominant over another, and the recessive allele does not appear in the phenotype at all. Some of the specific traits that Mendel was testing include pea color (yellow or green, with green being completely dominant) pea surface texture (wrinkled or smooth, with smooth being dominant) and flower color (pink and white, with pink being dominant.)
What is Gregor Mendel's Favorite color?
Gregor Mendel's favorite color was green read it in a biography about him.
What did Gregor Mendel reason from the existence of yellow and green seed colors?
Gregor Mendel reasoned that yellow seed color is dominant over green seed color based on his observation of the ratios of yellow to green seeds in his pea plant experiments. This led him to propose the concept of dominant and recessive traits in inheritance.
What are the 6 traits observed by mendel using green peas?
The six traits observed by Mendel using green peas were seed shape (round or wrinkled), seed color (yellow or green), flower color (purple or white), flower position (axial or terminal), pod shape (inflated or constricted), and pod color (green or yellow). He studied the inheritance patterns of these traits through his experiments with pea plants.

What kind of pea plants did Mendel use?
Smooth yellow pea plants and wrinkly green peas.

What did Mendel observe in the F2 offspring that showed him that the alleles for seed shape segregate independently of those for seed color?
Mendel observed a 9:3:3:1 phenotypic ratio in the F2 offspring, where the traits for seed shape and seed color were independently assorted from each other. This suggested that the alleles for seed shape (round/wrinkled) were segregating independently of the alleles for seed color (yellow/green).
What did Gregor Mendel reason from the existence of yellow and green seed colors?
Gregor Mendel reasoned that yellow seed color is dominant over green seed color based on his observation of the ratios of yellow to green seeds in his pea plant experiments. This led him to propose the concept of dominant and recessive traits in inheritance.
Do coloured leaves plants do photosynthesis?
YesThey also have green chlorophyll pigments.They are masked by colorful pigments like caratinoids.
What pea attributes did Mendel use?
Mendel crossbred -tall & dwarf pea plants, -green & yellow peas, -purple & white flowers, -wrinkled & smooth peas. And a few other traits.
What were Mendel experiment?
Gregor Mendel's experiments involved breeding pea plants with different traits (such as tall or short height, yellow or green seeds) and observing how these traits were inherited across generations. He formulated principles of inheritance, which later became known as Mendel's laws of inheritance. Mendel's experiments laid the foundation for the modern field of genetics.
Mendel crossed a true green podded plant with a true yellow podded plant. All the offspring from this cross had green pods. Green is the?
Green is the dominant trait in this cross. Mendel's results demonstrate that when a dominant allele (for green pods) is present, it masks the effect of the recessive allele (for yellow pods), resulting in all offspring exhibiting the dominant phenotype. Thus, the true yellow podded plant contributes a recessive allele that does not express in the presence of the dominant green allele.
