Question

Mendel study seven traits in P plants. What are the mono hybrid crosses he made it was between plant with round seeds and plants winkled seeds. What was the conclusion Mendel drew from the F1 generation of the cross? A.The dominant factor or allele is for round seeds. B. The dominant factor allele is for wrinkled seeds C.The factors or alleles for round seeds disappear completely from plants. D. The factors or alleles for wrinkled seeds disappear completely from the plants.

Answer 1

Answer:

A. The dominant factor or allele is for round seeds.          

Explanation:

After this cross, Mendel noticed that the trait for wrinkled seeds had disappeared. After observing that the first generation had rounded-seeds, such as one of the parental plants, Mendel called this variant, the dominant factor.

To study what had happened to the other trait, Mendel let the plants auto-fertilize and sow that in the second generation the disappeared trait, appeared again. He named the alternative variant recessive factor.

He thought that each individual carries a pair of factors for each characteristic and that the members of this pair segregate during gamete formation. This is known as the segregation principle.                

Answer 2

Answer:

The answer is A ; Mendel drew from the F1 generation of the cross that the dominant factor or allele is for round seeds

Explanation:

Mendel study is one coined into mendelism. It involves the whole body of principles of heredity formulated by G. Mendel, that represent the basis of genetics. Simply put the study of heredity of character.

Based on Mendel's observations of traits in the F1 and (F2 generations just an addition), He drew the following conclusions:

• Each parent in his F1 generation starts with two hereditary "factors."

One factor (now called allele=types of genes) is dominant (marks/coverup) and the other is recessive (can't be seen).

• The factors (alleles) separate in the parent. Only one factor (allele) from each parent is contributed to the offspring.

• Each offspring inherits one factor (allele) from each parent. If the dominant factor is present it will be expressed (seen) even if the recessive (unseen) factor is also present. The recessive factor will be expressed (seen) if only recessive (unseen) factors are present.

Mendel drew from the F1 generation cross that the dominant factor or allele is for round seeds and the recessive factor is for the wrinkled seed.
