how many human traits are controlled by a single gene?

Answers

Answer 1

Answer:

Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type. There are three common alleles for this trait, which can be represented by the letters A, B, and O.

is my answer correct ?


Answers

No, the option you chose is wrong. Salad dressing is a suspension & the oil & the particles gets settled when left undisturbed (2nd option.) Oil & water (the other particles) are immiscible, so it's a suspension. Some salad dressings can be a colloid as well. But, the 2nd option suits better here.Your answer is wrong because in a suspension, the particles are big & aren't informally distributed throughout the mixture. That's only in a solution/colloid. Suspensions have particles that are unevenly distributed & are big enough to scatter light until they settle down (Tyndall effect).

Some bacteria are aerobic and others are anaerobic. What does this mean?
A.
Some use H2O (water), and others do not.
B.
Some use CO2 (carbon dioxide), and others do not.
C.
Some use air, and others do not.
D.
Some use O2 (oxygen), and others do not.

Answers

Answer:

D. Some use O2 (oxygen), and others do not.

Explanation:

Bacteria can either grow aerobically or anaerobically. Because of their ability to respire and ferment organic substances, these types of bacteria (facultative anaerobes), can continue growing in the presence or the absence of oxygen.

Hope this helps! Please Mark BRAINLIEST.

Answer:

They would perform aerobic processes.

Explanation:

When exposed to a lack of oxygen, facultative anaerobes develop metabolic processes with oxygen, like respiration. But in the absence of oxygen, they can develop processes like fermentation. When in oxygen, they prefer the use of it, because that's what makes them facultative, the fact that they're able to work in both circumstances. Otherwise, tolerants are able to survive but not to work properly, in different environments.

Hox genes are regulatory genes in multicellular animals that code for transcription factors that determine the basic body plan in a developing embryo. They act as switches that turn other genes on and off. Scientists have found that a mutation in a fruit fly hox
gene produces flies with legs instead of antennae sticking out of their heads. Another hox gene mutation results in fruit flies with
two pairs of wings instead of one pair. Hox genes affect body plans by controlling the expression of many other genes
Many multicellular animals have the same hox genes. Which statement is evidence for this claim?
(1 point)
O There is a wide variety of body plans in complex animals.
o The body plans of complex animals are very similar to one another
The body plans of complex animals change over generations
The body plans of complex animals typically have a large number of mutations.

Answers

Hi! Welcome to Brainly! Thanks for asking a question!

So, based on the options provided in the question above, the correct option would be 'the body plans of complex animals are very similar to one another' or in other words Option B or 2.

Hope this helped! Happy holidays!

The correct option is The body plans of complex animals change over generations.

What are hox genes?

Hox genes are important regulators of how the animal body plan is organized. They contain transcription factors that when combined can give instructions to cells at various body levels on their potential morphological contributions.

In addition to its historical role in the anterior-to-posterior (AP) axis, HOX proteins also help to organize secondary axes and a number of different organs and tissues. Hox genes are grouped together in the genomes of many species that exhibit bilateral symmetry.

Because the sequence of genes in cis inside the cluster corresponds to the order of their expression domains along the various axes, this specific genomic architecture has functional significance.

Therefore, The correct option is The body plans of complex animals change over generations.

what will be the result if a eukaryotic cell completes mitosis but does not undergo cytokinesis?

Answers

A cell that completed mitosis but does not undergo cytokinesis PRODUCES one cell with two nuclei, each identical to the nucleus of the parent cell. Cytokinesis is the last phase of cell division.

Cytokinesis is the process by which a parental cell divides its cytoplasm to produce two genetically identical daughter cells, each one containing one cell nucleus.

Cytokinesis occurs in both types of cell division, i.e., mitosis and meiosis.

In animal cells, cytokinesis occurs by the emergence of a contractile ring that appears just beneath the cell membrane.

Cell membranes acts as a barrier for the large,charged and polar molecules due to their hydrophobic nature.

These molecules are transported with the help of membrane proteins such as carrier proteins across the plasma membrane by a process known as facilitated diffusion. These membrane proteins diffuse larger molecules across the cell membrane that cannot be transported by simple diffusion.

Which statement is true of carriers? Select all that apply.

A) They have one dominant allele.
B) They express the recessive trait.
C) They are heterozygous for a recessive disorder.
D) They can pass a gene for a recessive disorder.

Answers

B. They express the recessive trait

The carriers for a disease in a pedigree analysis is a heterozygous. They contain a dominant and a recessive allele. Thus, correct options are A, C and D.

What are genes?

A gene is a segment of DNA that contains all the information for the development of organism. A carrier in genetics, is an individual who “carries” and can pass on to its offspring an allele associated with a disease and does not show symptoms of that disease. A carrier is an organism that carries two different alleles of a recessive gene and is thus heterozygous for that the recessive gene.

Dominant genetic disorders are those in which a mutation in just one copy of the gene pair is required for the disorder to develop. However, in recessive genetic disorders both alleles need to be recessive for the gene. This disease symptoms are only observed in case of homozygous condition.

Therefore, the correct options are A, C and D.
