In Mendels Experiment Why Did Wrinkles Seeds Show Up In The F2 Generation Even Though They Were Not Present In The F1 Generation?
(Apex Learning) The F1 generation carried recessive alleles.
Mendel experiments why did wrinkle seed show up in the front F2 generation even though they were not present in F1 generation?
In Mendel's experiments, the wrinkled seed trait reappeared in the F2 generation due to the segregation of alleles. The F1 generation consisted of heterozygous individuals (Rr), where the dominant round seed allele (R) masked the expression of the recessive wrinkled seed allele (r). During gamete formation, the alleles segregated, leading to a 3:1 phenotypic ratio in the F2 generation, where the wrinkled seeds (rr) emerged when two recessive alleles were combined. This reappearance demonstrated the principle of segregation and the inheritance of traits.
What variables present in redi's experiment on spontaneous generation is not a controlled variable?
The presence of living organisms in the meat jars was not a controlled variable in Redi's experiment on spontaneous generation. This variable was dependent on the conditions set by Redi, rather than being controlled by him.
What did Pasteur's conclude from his experiment?
Louis Pasteur concluded from his experiment that spontaneous generation does not occur, and that microorganisms present in the air were responsible for the contamination of the broth. This observation led to the development of the germ theory of disease and revolutionized our understanding of infectious diseases.
Why did traits show up in the f2 generation that were not present in the f1 generation in Mendel27s experiment?
Traits that were masked in the F1 generation reappeared in the F2 generation due to Mendel's law of segregation. During gamete formation, alleles segregate randomly so that each gamete carries only one allele for each trait. When F1 hybrids are crossed, the recessive allele can be passed down and result in the expression of the trait in the F2 generation.

In Mendel's experiment why did wrinkled seeds show up in the f2 generation even though they were not present in the f1 generation.?
(Apex Learning) The F1 generation carried recessive alleles.
In Mendel's experiment, why did wrinkled seeds show up in the F2 generation, even though they were not present in the F1 generation?
(Apex Learning) The F1 generation carried recessive alleles.
In Mendel's experiment why did wrinkled seeds show up in the F2 generation even though they were not present in the F1 generation?
Wrinkled seeds are recessive The F1generation carried recessive alleles.
In Mendels experiment why did traits show up in F2 generation that were not present in the F1 generation?
All of the F1 generation are heterozygous, therefore 100% exhibit the dominant phenotype. The F2 generation has a ratio of 1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. This results in a phenotypic ratio of 3 dominant: 1 recessive.

the traits were recessive
What is the present tense for is?

Why did redi perform a second experiment?
Redi performed a second experiment to address criticisms of his first experiment that suggested the appearance of maggots in the decaying meat may have been due to spontaneous generation from microscopic organisms present in the air. The second experiment further demonstrated that maggots only formed when flies had access to the decaying meat.
What is the present generation of computer called?
Fourth Generation
