  • Genetic inheritance controls the characteristics of all living things.
  • Genetic inheritance involves understanding how our genes are inherited from our parents, and the different combinations of these genes make us unique.
  • Genetic inheritance explains that our genes are inherited from our parents, and the different combinations of these genes make us unique.
  • The allele for brown eyes is dominant.
  • Heterozygous refers to a genotype in which the two alleles for a particular characteristic are different.
  • A recessive allele will remain dormant unless it is paired with another recessive gene.
  • In a homozygous genotype, alleles are both identical for the same characteristic, for example AA or aa.
  • In a heterozygous genotype, alleles are both different for the same characteristic, for example Aa.
  • An allele is only expressed if the individual has two copies and does not have the dominant allele of that gene.
  • Most characteristics are a result of multiple genes interacting, rather than a single gene.
  • Recessive alleles are represented by a lower case letter, for example, a.
  • The allele for blue eyes is recessive.
  • Homozygous refers to a genotype in which the two alleles for the characteristic are identical.
  • Dominant alleles are represented by a capital letter, for example, A.
  • An allele is always expressed, even if one copy is present.
  • These genes could be the same, or different versions, known as alleles.
  • Each gene might have different forms, and these are called alleles.
  • One chromosome in each pair carries the same gene in the same location.
  • Alleles may be either dominant or recessive: A dominant allele always expresses itself whether it is partnered by a recessive allele or by another like itself.
  • The genotype is the collection of alleles that determine characteristics and can be expressed as a phenotype.
  • For example, the gene for eye colour has an allele for blue eye colour and an allele for brown eye colour.
  • Chromosomes are found in the nucleus of a body cell in pairs.
  • Alleles are different versions of the same gene.
  • The unit of heredity, a gene, may be copied and passed on to the next generation.
  • A gene is the basic unit of genetic material inherited from our parents.
  • Some characteristics are controlled by a single gene, such as fur in animals and red-green colour blindness in humans.
  • A gene is a small section of DNA on a chromosome, that code for a particular sequence of amino acids, to make a specific protein.
  • For any gene, a person may have the same two alleles, known as homozygous or two different ones, known as heterozygous.
  • Chromosomes are structures found in the nucleus of most cells.
  • A gene is a section of DNA which controls part of a cell's chemistry - particularly protein production.
  • Chromosomes are long threads of DNA, which are made up of many genes.
  • Genetic inheritance controls the characteristics of all living things.
  • Genetic inheritance involves understanding Mendel's work and carrying out genetic crosses.
  • Genetic inheritance involves understanding family trees and understanding the extent of genetic testing.
  • Genetic inheritance involves understanding the limits of genetic testing.
  • Genetic inheritance involves understanding the extent of genetic testing.
  • Genetic inheritance controls the characteristics of all living things.
  • Genetic inheritance involves understanding how our genes are inherited from our parents, and the different combinations of these genes make us unique.
  • The inheritance of fur colour in mice is controlled by a single gene, with white fur being recessive and grey fur being dominant.
  • Two mice that are heterozygous for the fur colour gene mate, with a 75% probability that the offspring will have grey fur and a 25% probability that the offspring will have white fur.
