Where are Mendel's factor's located?
Mendel's factors, now known as genes, are located on chromosomes within the cells of living organisms. Each gene occupies a specific position, or locus, on a chromosome, and these chromosomes are found in the nucleus of eukaryotic cells. Mendel's work laid the foundation for understanding inheritance patterns, revealing how traits are passed from one generation to the next through these genetic units.
What can you conclude about Gregor Mendel from the information presented in the movie?
he established all the principles of modern genetics
Was mendel one of the first scientists to discover the basic mechanisms of heredity in the mid -1800s?
yes he was. its true
In the late 1800s Mendel predicted the existence of units of hereditary information or factors What do you call these units of hereditary information today?
genes
What are Mendeln factors now called?
Mendel's factors are now known as genes. These units of heredity are responsible for the transmission of traits from parents to offspring, following the principles of inheritance first outlined by Gregor Mendel in the 19th century. Genes are segments of DNA that encode instructions for building proteins, which play critical roles in the development and functioning of living organisms.
What generation did Mendel get when he crossed the plants that produced the F1 generation?
100% percent of the plants expressed the dominate trait ........................................................................................ what do u get when u mix purple with purple you get 100% purple :) simple peace of cake !
How did mendel the F1 generation for his experiments?
he crossed two pure lines
How did Mendel make the F1 generation for his experiment?
he crossed two pure lines
What happened when mendel crossed a true- breeding?
When Mendel crossed true-breeding pea plants with different traits, he observed that the offspring in the first generation (F1) all displayed one of the parental traits. This led him to propose the Law of Dominance, which states that one trait will mask or dominate another in hybrids.
What was the original generation for pea plants in Mendel's experiment called?
The original generation for pea plants in Mendel's experiment is called the P generation, or parental generation. This generation consisted of the true-breeding plants that Mendel used to establish the traits he studied. The P generation was crossed to produce the F1 generation, which exhibited the traits inherited from the P generation.
What did Mendel's work first and second generation mean?
In a typical Mendel experiment, Mendel took two purebreeding lines (the parental generation) and crossed them to produce the 1st filial generation and sometimes would self cross these to produce the 2nd filial generation.
Mendel crossed a purebred tall plant with a purebred short plant. What was the phenotype of the f1 generation?
The phenotype of the F1 generation was all tall.
What was the original generation of pea plants in mendels experemint called?
The original generation of pea plants in Mendel's experiments is called the P generation, or parental generation. This generation consists of the true-breeding plants that Mendel used to establish the traits he studied in subsequent generations. The P generation's offspring are referred to as the F1 generation, which Mendel observed for inheritance patterns.
What are the phenotype of the f2 generation that Mendel observed?
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).
What did mendell hypothesize about first generation plants?
Mendel hypothesized that first-generation plants, when crossed, would display a dominant trait in their offspring. He observed that when he crossed purebred plants with contrasting traits, such as tall and short pea plants, the resulting first-generation (F1) plants exhibited only the dominant trait. This led him to propose the concept of dominance in inheritance, suggesting that some traits mask the expression of others in the presence of a dominant allele.
What did Mendel call the trait that appeared in all of his first generation plants?
Mendel referred to the trait that appeared in all of his first-generation plants as the "dominant" trait. In his experiments with pea plants, he observed that when he crossed different varieties, one trait would consistently manifest in the offspring, overshadowing the other trait, which he termed "recessive." This foundational concept established the basis for understanding inheritance patterns in genetics.
Did Gregor Mendel discover that traits are passed from generation to generation?
Yes, Gregor Mendel's experiments with pea plants in the 19th century led to the discovery of the basic principles of inheritance. He observed that traits are passed from generation to generation in a predictable manner, which laid the foundation for the field of genetics.
