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".

Question 4 (1 point) If 18 grams of oxygen reacts completely with 4 grams of hydrogen, we would expect how many grams of water?
Lisa [10]

Answer:

C.22 grams because mass cannot be created or destroyed

Explanation:

Reaction equation:

        2H₂  +   O₂    →   2 H₂O

Mass of oxygen  = 18g

Mass of hydrogen  = 4g

The mass of water produced is 22g according to law of conservation of mass.

The law states that " in a chemical reaction, mass is always conserved"

 The sum of the mass of product  and reactants must always be the same.
