In each of the scenarios, an individual heterozygous for the indicated gene or genes is crossed with an identical heterozygous i

ndividual. Predict the number of different phenotypes that would be observed among the progeny of such a cross.
Scenario 1: R is completely dominant to r.
Scenario 2: R is incompletely dominant to r.
Scenario 3: R and s are completely dominant to rand s, respectively: R and S are linked by 10 m.u. and don't interact with each other.
Scenario 4: Genes R and S perform the same finction: R and S are completely dominant to r and s, respectivley' and R and S are unliked.
Scenario 5: R and S are completely dominant to r and s, respectively; R and S are unlinked show dominant epistasis.

The brothers pictured below are identical twins. The boys in this picture look alike because their bodies contain identical carb
Romashka [77]

Answer:

nucleic acids.

Explanation:

The fusion of the sperm with the egg results in the formation of a zygote that develops into a new offspring. Twins refers to the two offspring which are a result of the same pregnancy. They are of two types. Monozygotic twins are a result of the single zygote (formed by the fusion of one egg with a single sperm) spiltting into two embryos forming the identical twins. Dizygotic twins are a result of two eggs fertilized with two different sperms forming the fraternal twins.

Identical twins are genetically simliar. The genetic material is derived from the same embryo and thus, the DNA of the identical twins are nearly identical. The spilitting of the embryo formed results in the separation of the same genetic material or identical DNA getting incorporated into the twins making them look alike in majority of the cases.

  • Anaphase
  • Telophase

Telophase is the last phase of karyokinesis. The main events that occur during telophase are-

  • Uncoiling of chromosome occurs
  • Chromatin is formed
  • Spindle breaks down
  • Nuclear membrane or nuclear envelope if reformed

Thus it is clear that the events that are mentioned in the question denote truly about the Telophase.
