Which of the following are true. 1.single gene can control a single trait 2.single gene can influence multiple traits 3.single trait can be controlled by multiple genes?
All of them.
Who always wins a dominant gene or a recessive gene?
The dominant gene always win because it is represented by upper case letters. And the recessive genes loses all the time because it is represented by a lower case letter.A dominant gene in most cases. If it an autosomal trait (on body cells) in all cases the dominant gene will win. In the case with x, sex linked recessive traits the recessive trait will appear in males if only one gene is presentA dominant gene in most cases. If it an autosomal trait (on body cells) in all cases the dominant gene will win. In the case with x, sex linked recessive traits the recessive trait will appear in males if only one gene is present
What are genes and alleles?
The functional part of DNA is a gene. All the DNA in an organism does not code for protein. In fact, only a fraction of the genome codes for protein. The part of the DNA that codes for protein is called a gene. Different forms of the same gene are called alleles. There are alleles controlling phenotypic features such as eye color and height of the individual Although these features are controlled by the same gene, different features can result depending on which allele is expressed.
What is an example of recessive trait?
'Albinism' (being an albino, without skin pigmentation) is an example of a recessive trait. Specifically, it is an expressed recessive trait, because that person does not have the dominant gene at all, only two copies of a recessive gene. For a person to be an albino, his/her parents BOTH had to have the recessive gene and the offspring had to inherit THOSE TWO copies and can now only 'express' the recessive gene. There is no dominant gene to undo the albino trait. Side note: there is more than one form of albinism recognized in medical science, but all are examples of recessive traits. Another example of a recessive trait would be 'sickle-cell disease/anemia.'
The gene pool for a particular gene is?
a gene pool is the mixture of a group of a species' genes. like, if you took all of the DNA of a group of people, and mixed it all together, that would be a gene poolThe total of all alleles present in a population.All of the alleles in one population
Which will give a trait the fewest phenotype?
if its all controlled by one gene
Are traits controlled by the interaction of two or more genes?
or one gene, all by its lonesome.
Which of the following are true. 1.single gene can control a single trait 2.single gene can influence multiple traits 3.single trait can be controlled by multiple genes?
All of them.
Is a gene all of an organism's DNA or only a segment of DNA?
A gene is a portion on a chromosome. It is not the entire DNA which codes for all you see in an individual.
Is a gene all of an organisms DNA or only a segment of DNA?
A gene is a portion on a chromosome. It is not the entire DNA which codes for all you see in an individual.
Who is the only person to have all 5 stars?
Gene Autry
What country is Gibraltar controlled by?
Everyone thinks that it is controlled by Spain, BUT that is NOT true at all. I will type this once and only once only. GIBRALTAR IS CONTROLLED BY THE UNITED KINGDOM!!!! Thanks for asking this question and getting the answer from me!
When mendel crossed a strain of tall pea plants with a strain of short pea plants he observed that all the f1 generation were tall this suggest that?
the tall trait was controlled by a dominant factor.
Is essential characteristics the same as characteristics?
No, essential means only the ones most needed, so essential characteristics would be a subset of all characteristics.
Which type of muscle is controlled at will by impulses from the brain?
All muscles are controlled by impulses from the brain. Skeletal muscle is, with few exceptions, the only type of muscle that can be controlled at will.
What are controlled drugs?
So-called "controlled substances" are narcotic and narcotic-type drugs strictly controlled by law and, if availalbe at all, are only available with a valid/legal prescription.
Do all versions of each gene always get expressed in an organism?
No, only dominant traits will be expressed.
