Adaptations 1
Who discovered animal adaptations
Charles Darwin
The allele composition of the chromosomes is known as?
The genotype
Allele
Different forms of a gene (one from mother and one from father)
RNA
Ribonucleic acid & is a nucleic acid that plays an important role in the production of proteins. Acts as a messenger that changes the language of the DNA
To understand adaption we must?
Think in terms of cell biology
The first chromosome on the left is?
Is homozygous dominant
Dominant
An allele that is always expressed
DNA
Deoxyribonucleic acid genes segment of DNA that is located in a chromosome and that codes for a specific hereditary trait
Alleles are essentially either?
The mother or fathers form of gene
The second chromosome is
homozygous recessive
Recessive
An allele that is masked when a dominant allele is present so it is NOT expressed
DNA replication
When DNA makes a copy of it's self
Genes and their alleles are defined
Stretches of DNA because of mutations
The third chromosome is
heterozygous dominant
Genotype
Collection of all genes
Traits that allow plants or animals species to survive in a particular environment
Adaptations
The fourth chromosome is also
heterozygous dominant
Phenotype
An organism's physical appearance or visible traits
Genes
segment of DNA that is located in a chromosome and that codes for a specific hereditary trait
