Define ‘Homologues Chromosomes’.
‘Homologues Chromosomes’ are chromosomes with the same type of genetic information.
Define ‘Autosomes’.
Any body or non-sex chromosomes.
Define ‘Carriers’.
When an organism has or “carries” a genetic difference in one copy of a gene but doesn’t have the disease.
Define ‘Allele’.
A variation of a gene that can result in different traits.
Define ‘Phenotype’.
‘Phenotype’ is the physical characteristics of a person.
Define ‘Genotype’.
‘Genotype’ is the genetic makeup of a person.
Define ‘Dominant’.
‘Dominant’ is used to describe an allele or a trait that is always expressed in the phenotype.
Define ‘Recessive’.
‘Recessive’ Section of genetic information with a low probability of being expressed.
Define ‘Heterozygous’.
‘Heterozygous’ is when the alleles for a trait are different.
Define ‘Homozygous Dominant’.
‘Homozygous Dominant’ is a genotype where an individual inherits two copies of a dominant gene.
Define ‘Homozygous Recessive’.
‘Homozygous Recessive’ is if it carries two copies of the same recessive allele.
Define ‘Monohybrid Cross’.
‘Monohybrid Cross’ is a design used to study the inheritance of a trait or gene.
The process of cell division that produces the gametes in the sex organs is?
‘Meiosis’ is the special process of nuclear cell division that results in the production of sperm or ova cells.
The alternative forms of each gene are called?
‘Alleles’ is a variation of a gene that can result in different traits.
Define ‘Haploid Cells’.
‘Haploid Cells’ are cells that contain a singular set of 23 chromosomes.
