As a result of his experiments with dihybrid crosses, Mendel observed that the presence of one trait had no affect on the presence of another trait. Gregor Mendel was a scientist who became known as the founder of modern genetic science.

What do biologists call the offspring of crosses between parents with different traits?
Are called hybrids
Mendel referred to the characteristic that was expressed in the hybrid F1 or first filial generation as?
Dominant
How did Mendelssohn results from hybrid crosses help him develop the law of independent assortment?
no se
Explain Mendel's law of independent?
Mendel's Law - The first law of Mendel states that "In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype."
What is Gregor Mendel known to be the father of?
Gregor Johann Mendel is considered as the father of genetics because of his experiments with pea plants, whereby he discovered recessive and dominant "characteristics". His work was more or less forgotten for decades. The word "genes" was thought up later. Gregor Mendel, who is known as the "father of genetics/father of genetic discovery/father of modern genetics", was inspired by both his professors at university and his colleagues at the monastery to study variation in plants, and he conducted his study in the monastery's garden. Between 1856 and 1863 Mendel cultivated and tested some 29,000 pea plants (i.e. Pisum sativum). This study showed that one in four pea plants had purebred recessive alleles, two out of four were hybrid and one out of four were purebred dominant. His experiments brought forth two generalizations, the Law of Segregation and the Law of Independent Assortment, which later became known as Mendel's Laws of Inheritance.
In the design of Mendel's experiment why is it important that all members of the series developed in each successive generation should be without exception subject to observation?
The possibility of accidental impregnation by foreign pollen, possible sterility of hybrid crosses are two factors that lead Mendel to insist on close scrutiny. He insisted that all members of the series developed in each successive generation should be, without exception, subjected to observation.
How are the principles of probability used to predict the outcomes of genetic crosses?
Whenever Mendel performed a cross with pea plants, he carefully categorized and counted the many offspring. Every time Mendel repeated a particular cross, obtained similar results. For example, whenever Mendel crossed two plants that were hybrid for stem height (Tt), about three fourths of the resulting plants were tall and about one fourth were short. Mendel realized that the principles of probability could be used to explain the results of genetic crosses.
Term mendel used to describe two different allele combinations?
Mendel used the term hybrid when referring to a trait with two unlike alleles.
How did Mendel produce hybrid pea plants?
losers
What did mendel predict was the probability of producing a tal plant from a genetic cross of two hybrid tall piants?
The principles of probability explained the numerical results of Mendel's experiments. In one of his experiments, the probability that an F2 plant would be tall was 75%.
What factors contribute to the success of Mendels experiment?
the reason they are so reliable is because he used peas as his plant of interest. an peas have only 2 different things they can be. short or tall. so it was easy to conclude all of the different outcomes of the offspring of the pea plants because of the of his drawn punnett square. which shows that if a tall dominant pea plant goes with a short it will be tall. and if it goes with a tall it will be tall. but if short goes with short then it will be short. so only 25% vof the time a pea plant will be short
What do biologists call the offspring of crosses between parents with different traits?
Are called hybrids
Which term did Mendel use when referring to a trait with two unlike all?
hybrid
How do you explain Mendel's mono hybrid cross 1?
Mendel crossed a pure-breeding round-seeded variety with a pure-breeding wrinkled-seeded one. All the peas produced in the second or hybrid generation were round.
Solve problem between monohybrid and dihybrid cross?
Mendel's main experiments where mono hybrid crosses. A mono hybrid cross is a cross that involves 1 pair of contrasting traits, an example is a crossing plant with purple flowers and a plant with white flowers is a mono hybrid cross.
Which term did mendel us when referring to a trait with two unlike alleles?
Mendel used the term hybrid when referring to a trait with two unlike alleles.
Which term Mendel use when referring to a trait with two unlike allelles?
Mendel used the term hybrid when referring to a trait with two unlike alleles.
