When Mendel crossed a plant homozygous for round seeds to another plant homozygous for wrinkled seeds, he found that all the pro
deff fn [24]

Answer:

a. The allele for round seeds is dominant to the allele for wrinkled seeds.

Explanation:

Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.

A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".

Strike441 [17]

Answer:

????

3. See answer to 2

4. It's cut off? But observations can literally be as simple as looking at a stick and noting that it's brown, so from what I can read, it's invalid.

Virty [35]

Answer:

True breeding

Explanation:

True breeding is a breeding in which parents produce the offspring which carry same phenotype.  

The parents in true breeding are homozygous for every trait.  

<u>True breeding occurs in the plants when the plants produce offspring of same variety only when self pollination takes place.  </u>

<u>For example, if a plant has purple flowers will produce only seeds which will grow into plants which have purple flowers.</u>
