It occurs when a child inherits a chromosome with extra or missing genetic material from a parent with a balanced translocation.

Robertsonian translocations can occur.

The arms of the chromosome are not the same proportion as a person with normal chromosomes that do not have a mutation.

Difficulties include reproductive consequences, Down syndrome, congenital heart disease, and learning disabilities.

In Oompa Loompas, gray face (G) is dominant to orange recessive face (g). If two gray faced Oompas have an offspring with an ora
Neko [114]

Answer:

The genotype for each of the parents must be

parent 1 : Gg

parent 2 : Gg

Explanation:

Please note that a dominant trait is a trait that is expressed phenotypically in a heterozygous state, while a recessive trait is a trait that can only be expressed in a homozygous state.

Now, since gray face (G) for Oompa Loompas is dominant, and orange face (g) is recessive, for an offspring to be orange faced, it means that the genotype of the offspring must be 'gg'. Also, since both parent contribute an allele in the pair of alleles in the offspring, both parents must have the recessive (g) in their genotype. Moreover, we are told that both parents are gray-faced, meaning that their genotypes were 'Gg' and 'Gg'. To confirm, let me do the cross

                                 G           g

G                                GG       Gg

g                                 Gg        gg

from the cross above, we find out that out of 4 offspring, 3 were gray face (GG, Gg ) while one was orange face (gg).

Products are what is created during a reaction. What are the three products of cellular respiration
Setler79 [48]

Answer:

The three products of cellular respiration are:

  1. ATP
  2. Water
  3. Carbon dioxide

Explanation:

  • Cellular respiration is the process of breaking down glucose molecules to yield energy in the form of ATP.
  • C6H12O6 + 6O2 → 6CO2 + 6H2O

ATP Production:

  • The first step of cellular respiration, glycolysis, yields 2 net ATP.
  • The second step, Kreb's cycle produces 10 NADH and 2 FADH2 molecules. Both these molecules store energy that is released in the electron transport chain to produce 34 ATP.
  • Therefore, a total of 36 ATP are produced as a result of cellular respiration in eukaryotes.

Carbon dioxide Production:

  • 2 molecules of CO2 are produced during the conversion of pyruvate into Acetyl Co-A by the <em>pyruvate dehydrogenase</em> complex.
  • 4 molecules of CO2 are produced in the Kreb's cycle.

Water Production:

  • Water is produced in the Electron Transport Chain (ETC) by the reduction of oxygen.

Which statements describe the function of each type of macromolecule? Check all that apply.
siniylev [52]

Answer;

-Proteins play a role in transport, enable movement, provide structure and support, and help make chemical reactions happen.

-Nucleic acids carry genetic information, determine the structure of proteins, and help build proteins.

Explanation;

-Biological macromolecules are the large molecules necessary for life, include carbohydrates, lipids, nucleic acids, and proteins.

-Each of these types of macromolecules performs a wide array of important functions within the cell; a cell cannot perform its role within the body without many different types of these crucial molecules.

Which statement best summarizes the importance of meiosis to reproduction?
Vesna [10]

Answer: The correct answer is It produces gametes that are needed for sexual reproduction.

Explanation-

Meiosis is a type of cell division, which is a characteristic feature of sexually reproducing organisms. It produces reproductive cells called gametes, which possess half number of chromosomes as compared to their parental cells ( which are diploid). Gametes from each parent fuse to form a diploid zygote that develops into an individual.

Thus, it summarizes the importance of meiosis to reproduction.
