What are sections of a chromosome that are code for trait?
A section of chromosomes that codes for a trait can be called
What is a section of DNA that determines a trait?
a section of DNA has information about a specific trait of an organism is called what?
What makes something a sex-linked trait instead of just a regular trait?
A sex linked trait can only be found on the x chromosome such as hemophilia, color blindness, and muscular dystrophy. These are traits that can only be inherited through chromosomes instead of regular traits coming through genes.
What is a section of DNA that code for a trait?
A section of chromosomes that codes for a trait can be called
What determines a specific trait?
DNA determines a specific trait.
A unit that determines that trait?
A unit that determines a trait is called an allele
What determines a Mendelian trait?
Chromosomes do not have a sex/gender but determine it. In humans, females have two X chromosomes (XX) and males have an X and a Y chromosome (XY).
If a gene is located on the human X chromosome it is more likely that a male will express the trait that the gene codes for?
If the trait is recessive, then yes.Male humans have only a single X chromosome, while females have two. Men need only 1 allele to be effected, while women need 2.
What contains only a single instruction for determining a trait in an organism 1.dna molecule 2. gene 3.chromosome 4.cell?
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.
Is Down syndrome a single gene or polygenic trait?
Down syndrome is a result of having an extra chromosome in one's genes. Chromosome thirteen* if your that much into the science. It is also called trisomy 21 because the chromosome 21 is the one with the abnormalities. *Abnormalities with chromosome thirteen is called Patau syndrome or trisomy 13.
Each gamete gets one gene from each trait?
Each reproductive cell (gamete) is 1N (the haploid chromosome count) which means it has a single allele for a genetic trait at each gene locus...this is based on the assumption that the trait is controlled at a single site. Polygenic traits, those controlled or modified at more than one locus, will have multiple alleles for a trait.
