What does pleiotropy mean?
Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits (those you see). A series of defects that affect multiple systems but is caused by one defective gene.
When both alleles contribute to the phenotype it is called?
PleiotropyPleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits, an example being phenylketonuria, which is a human disease that affects multiple systems but is caused by one gene defect.
What is the gene pyramiding?
It is a method aimed at assembling multiple desirable genes from multiple parents into a single genotype.
When one gene controls two or more phenotypic traits?
polygenic inheritance
Is the three alleles of the single gene that controls blood type is said to be what alleles?
multiple alleles
What is the definition of pleiotropy?
The production by a single gene of multiple phenotypic effects
What is a gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
WHAT is single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
What does pleiotropy mean?
Pleiotropy occurs when one gene influences multiple, seemingly unrelated phenotypic traits (those you see). A series of defects that affect multiple systems but is caused by one defective gene.
A characteristic of an organism that is determined by many genes?
The terms used to describe a number of genes on separate loci on the same chromosome (or another chromosome) which together determine a single phenotypic trait are polygene, multiple factor, multiple gene inheritance or quantitative gene.
What is gene cloning?
The production of multiple copies of a single gene.
What are genes with three or more alleles called?
this makes no scientific sense. A gene (which determines a phenotypic trait) can only contain 2 alleles. However codominace allows for multiple alleles to be chosen from, but only 2 picked for a gene. Also, if multiple genes determine a phenotypic trait that's polygenic inheritance.
Is sickle cell anemia a single gene defect or multiple gene?
Sickle Cell Anaemia is a single gene defect (Hb gene).
What are modifier genes?
modifier gene is a gene that alters phenotypic expression of another gene
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.
What is the definition of multiple gene inheritance?
Any of a group of nonallelic genes, each having a small quantitative effect, that together produce a wide range of phenotypic variation. Also called multiple factor, quantitative geneAny of a group of nonallelic genes, each having a small quantitative effect, that together produce a wide range of phenotypic variation. Also called multiple factor, quantitative gene.
Can a single gene can influence multiple traits?
yes
