Only half of each parent's alleles are passed to their children.
This means that parent 1 who is Aa at one gene locus will only pass A or a on to each offspring.
Parent 2 may be AA, aa or Aa and will also only pass one allele on to each offspring.

How are physical traits passed on to offspring?
Short Answer: Genetics Practical Answer: 1/2 of the genes (or chromosomes) of each parent (in the egg from the mother and the sperm of the father) combine giving traits from both parents to the child.
What happens if you dont get any genes from a parent?
That is impossible, as each parent contributes 23 genes. You could not be born without 46 genes.
How many genes for each featuredo you inherit from each parent?
Traits can be determined by a single gene or by multiple genes. Many genes influence the regulation of others and sometimes even hide the existence of some. There isn't an answer to this question.
A child is diagnosed with a rare genetic disease neither parent has this disease how was the disorder inherited?
Recessive is carried by both parentsIn simplest terms, the disease is recessive, so two copies of the gene that cause it are necessary. Both parents have only one copy of the gene, so, they don't have it, but are carriers. A child gets half his or her genes from each parent. If the child gets the bad gene from each parent, the child will have the disease. There is a 25% chance of this happening with every child these parents have.
Each p1 parent of a monohybrid cross has completely identical genes?
False
How come some younger sister are taller than their older sister?
Each child that is NOT an identical twin receives a completely differant combination of genes from each parent. It is 100% random what traits will be passed on to each child, and most likely the genes given to two sisters were differant.
How many sets of genes do a child inherts?
A child inherits two sets of chromosomes which contain the genes. One member of each set comes from each parent.
The set of instrustions for making proteins that are coded in DNA and passed from parent to offspring each generation are called?
Genes.
What type of blood will a child have if both parents are positive types?
The child will probably be positive, but they can be negative. Each parent has two genes for pos/neg blood type. The parent will have positive blood type if at least one of their genes is positive, but they could both also have negative genes to pass on to the child.
Each parent donates a set of instructions called what to their offsprings?
The set of instructions for each characteristic passed from parent to offspring is called "genes", which are made up of complex molecules of DNA.
What is the very important concept of heredity did not yet understand?
We understand the basics, at least; certain traits are passed on from parent to child. Certain "genes" (tiny pieces of genetic information, encoded in a chemical form) from the parent will influence the development of the child. The child receives half of its genetic information from each parent. The fine details are pretty complicated, because while some inheritable traits are passed along by a single gene, most traits appear to be encoded in combinations of genes. Until we have a better understanding of how the combinations work together, we're going to be more-or-less guessing about what each gene does.
What is the process of the transmission of characteristics from parent to offspring?
Traits can be classified as autosomal dominant or recessive. A child receives alleles from each parent, a dominant trait requires one allele and a recessive requires both.
How do you look like parents?
Each parent has a set of genes that is passed on to his/her offspring (children) and which genes become apparent in the child is all dependent on whichever genes are dominant over the recessive genes. For example, one parent may have blue eyes (dominant) and another has green eyes (recessive); it is more likely that the child will have blue eyes than green eyes*. *This example was merely for explanation; I don't know if blue eyes are dominant over green eyes or not.

How could parents with blood type A and B have a child with blood type O?
If both parents had heterozygous blood-type genes, then the child could inherit the recessive O type from each parent. Suppose the mother had the genes for A and O, and the father had the genes for B and O. They would then have blood-types A and B respectively. Depending on which parts were passed to the child, any blood type would be possible.
What happens if you dont get any genes from a parent?
That is impossible, as each parent contributes 23 genes. You could not be born without 46 genes.
