How many genes are passed from parent to offspring?
One copy is inherited from their mother (via the egg) and the other from their father (via the sperm). A sperm and an egg each contain one set of 23 chromosomes. When the sperm fertilises the egg, two copies of each chromosome are present (and therefore two copies of each gene), and so an embryo forms.
What is the passing of genetic information?
Inheritance is the passing of traits from parents to offspring. Our modern understanding of inheritance comes from a set of principles proposed by Austrian monk and researcher Gregor MendelGregor MendelBy experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed. Mendel's insight greatly expanded the understanding of genetic inheritance, and led to the development of new experimental methods.http://www.nature.com › scitable › topicpage › gregor-mendel...Gregor Mendel and the Principles of Inheritance - Nature in 1865.
What percentage of genetic information is passed on from parents to their offspring?
The mix of the DNA is unique to an individual as we receive 50% of the DNA from each of the parent, who received 50% of their DNA from their parents and so on which keeps reducing over generations.

How would the allele BB be categorized?
We mostly use letters as an abbreviation for alleles, B = black, b = red. An individual that contains two copies of the same allele for a specific gene is homozygous. An individual that contains two different alleles of a gene is heterozygous. A cow that has two alleles for a red coat is homozygous (bb).
What store and pass on genetic information?
DNA stores hereditary information which provides instructions for the assembly of proteins.
What type of allele is BB?
With eye color, for instance, “B” stands for a brown allele and “b” stands for a blue allele. An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB.

How would the allele BB be categorized quizlet?
it is in a homozygous (BB) or heterozygous (Bb) pair. A recessive allele is only expressed when in a homozygous pair(bb).
What stores the genetic?
In living organisms, the genome is stored in long molecules of DNA called chromosomes.

Is BB genotype or phenotype?
The physical appearance of the genotype is called the phenotype. For example, children with the genotypes 'BB' and 'Bb' have brown-eye phenotypes, whereas a child with two blue-eye alleles and the genotype 'bb' has blue eyes and a blue-eye phenotype.
Is BB heterozygous or homozygous?
An individual that contains two copies of the same allele for a specific gene is homozygous. An individual that contains two different alleles of a gene is heterozygous. A cow that has two alleles for a red coat is homozygous (bb). A bull with two alleles for a black coat is homozygous (BB).
