The atomic number of an element is the number of protons in the nucleus of an atom of that element.
Atoms with the same number of protons, but a different number of neutrons are called isotopes.
Answer:
They have genes for the same traits
Explanation:
Answer:
1/3
Explanation:
<em>A standard monohybrid cross is a cross that follows the dominance/recessive pattern from Mendel's experiment.</em>
It means the purple flower color is dominant over the white flower color.
Assuming the allele for purple flower color is P and that of the white flower color is p, a standard monohybrid cross will involve a true breeding PP and pp.
PP x pp: Pp, Pp, Pp and Pp. All the F1 offspring will have purple flowers with Pp genotype.
At F2: Pp x Pp = PP, Pp, Pp, and pp.
3/4 or 75% of the F2 offspring have purple flower color out of which 1 is true breeding for the trait.
Hence the fraction of the purple flowered peas in the F2 that is expected to be true-breeding (PP) is 1 out of 3.
Answer:
The correct answer is (a). The brown beetle migrated to island #1 and gave rise to the colored species on island #2 through adaptive radiation.
Explanation:
As there are no brown beetles on the island 1, and island 2 has less biodiversity of plants, it's possible to think that the brown beetle migrated to island 1 where there are many kinds of different plants, which would lead to the adaptation of these organisms resulting in many different species.
