A persons' genes do determine height but the environment also does. Many people without enough food as a child will not be as tall as their genes saw that they should be.
Passive gene- environment correlations evocative gene- environment correlations active gene- environment correlation
types of gene environment interaction
Each person has two alleles for an autosomal gene, one inherited from each parent. These two alleles together determine an individual's genotype for that gene.
when a gene transfer to a person then other person is scared of the gene
a person can get it only if both of its parents are carriers, and if the child inherits the hexA gene from each parent.
There are a couple ways Tay-Sachs can be prevented; 1) determine if both you and your mate carry the Tay-Sachs gene 2) perform a prenatal diagnosis to determine if the fetus carries the Tay-Sachs gene Hope this helped!
Dominant gene can be passed down from person to person
The gene that determines a man's hair is on the x chromosome.
Homozygous. This means that both alleles for a particular gene are the same, either both dominant or both recessive.
the answer is sex chromosomes
An example of a gene with two different alleles is the gene for human blood type, which can have alleles for blood type A, B, or O. Each person inherits one allele from each parent to determine their blood type.
If both parents have sickle-cell anemia, their child will inherit one copy of the defective gene from each parent, making them a carrier. Thus, the likelihood that a person who has two parents with the disease will be a carrier of the defective gene is 100%.
