Answer Expert Verified. The best example of hypothesis which leads to new experiment methods was done by
Morgan where he used fruit flies
. Thomas Hunt Morgan continues on genetic research which is of Gregor Mendel.
Which is the best example of a hypothesis leading to new experimental methods Gregor Mendel influenced the development?
Which is the best example of a hypothesis leading to new experimental methods? Thomas Hunt Morgan continued the genetic research of Gregor Mendel, but Morgan
used fruit flies
. Scientists often use fruit flies as a method to test hypotheses about human genes.
Which statement best describes an understanding of genetics that would be missing without work of Mendel?

Why did Gregor Mendel use peas in his experiments?
Mendel studied inheritance in peas (Pisum sativum). He chose peas
because they had been used for similar studies, are easy to grow and can be sown each year
. Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinate.
Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds?
Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is a true breeding for yellow seeds?
The offspring will inherit one gene from each parent.
Which is the best example of a hypothesis?
- If I replace the battery in my car, then my car will get better gas mileage.
- If I eat more vegetables, then I will lose weight faster.
- If I add fertilizer to my garden, then my plants will grow faster.
- If I brush my teeth every day, then I will not develop cavities.
Which statement is the best example of hypothesis?
- If you get at least 6 hours of sleep, you will do better on tests than if you get less sleep.
- If you drop a ball, it will fall toward the ground.
- If you drink coffee before going to bed, then it will take longer to fall asleep.
What best describes the presence of freckles?
Which statement best describes the presence of freckles?
Freckles are not determined by DNA. There are two alleles for freckles. There is no dominant allele for freckles
.
What statement summarizes the law of segregation?
The law of segregation states that
each individual that is a diploid has a pair of alleles (copy) for a particular trait
. Each parent passes an allele at random to their offspring resulting in a diploid organism. The allele that contains the dominant trait determines the phenotype of the offspring.
What is inheritance and control traits?
Genes
have the most control of traits and inheritance.
They are the basic unit of inheritance.
What are the three steps of Mendel's experiments?
| P w | P PP Pw | w Pw ww |
|---|
What did Mendel conclude from his experiments?
Gregor Mendel, through his work on pea plants,
discovered the fundamental laws of inheritance
. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. … Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
What are Mendel's factors called today?
Mendel's “factors” are now known to be
genes encoded by DNA
, and the variations are called alleles. “T” and “t” are alleles of one genetic factor, the one that determines plant size.
What is the percentage of a homozygous dominant offspring?
| PARENT GENOTYPES OFFSPRING PHENOTYPES | pure (homozygous) dominant x anything 100% of offspring with dominant trait | hybrid x homozygous recessive 50% dominant trait, 50% recessive trait | hybrid x hybrid 75% with dominant trait & 25% with recessive trait | homozygous recessive x homozygous recessive 100% recessive trait |

What was the outcome of the F1 generation in Mendel's first experiment?
Figure 5.10. 5 shows Mendel's first experiment with pea plants. The F1 generation results from
the cross-pollination of two parent (P) plants, and it contains all purple flowers
. The F2 generation results from the self-pollination of F1 plants, and contains 75% purple flowers and 25% white flowers.
Why the garden pea was an excellent choice of model system for studying inheritance?
One of the reasons that the garden pea was an excellent choice of model systems for studying inheritance is that
the flowers close tightly during self-pollination to prevent accidental or unintentional fertilizations
that could have diminished the accuracy of Mendel's data.
