Answer:
D (purple flower plant is dominant)
Explanation:
Gregor Mendel was regarded as the "Father of Genetics" because of his outstanding contribution to discovering the pattern of inheritance. In his experiments with purebreeding purple and white-flowered plants, he discovered that the F1 offsprings were all purple-flowered.
This observation made him to propose his LAW OF DOMINANCE, which states that one allele of a gene is capable of masking the expression of another in a heterozygous state. In this case of flower colour gene, the allele for purple color (P) is masking the gene of the white colour (p) in a combined state. Hence, purple allele is said to be DOMINANT over white allele.
He discovered that the white allele was being masked when he performed a dihybrid cross i.e. F1 self cross to derive a plant with white flowers.
<span>An atom consists of a positively-charged nucleus, consisting of various combinations of protons and neutrons, and negatively-charged electrons which move around the nucleus in distribution patterns called shells. In a neutral atom, the number of electrons is equal to the number of protons, but an ionized atom would have more or fewer electrons. Electrons are much less massive than protons or neutrons.
(2) How are groups of atoms organized?
Atoms bond together with other atoms to form molecules or can be part of a crystal lattice. </span>
