biology chapter 9 Crossword

A section of DNA that carries the code to make a protein
alternative forms of a gene
the complete set of DNA contained within the haploid set of an organism's chromosomes.
double stranded nucleic acid chain made up of nucleotides. Carries the instructions for proteins which are required for cell
double ring structure; A and G
single ring structure; T and C
the structure made of protein and nucleic acids that carries genetic information
a visual representation of an individual’s entire genome organised into homologous pairs
Set of alleles present in the DNA of an individual organism. A result of inheritance.
A diploid individual with two identical alleles at a particular genetic locus
A diploid individual with different alleles for a particular gene
All of the observable characteristics of an organism. A result of inheritance and the environment.
The full phenotypic expression of both alleles is observed. Both genes are considered dominant.
A form of inheritance in which neither allele is dominant, and both are expressed. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles.
a trait that is under control of a single gene.
a gene which has a small effect on a phenotype, but works with other polygenes to produce observable variation in a trai

any external effect caused by scientific endeavours that relates to moral problems or quandaries, typically pertaining to real-world situations and contexts
changes to an organism’s phenotype resulting from modifications to gene expression
The conditions and resources external to an organism with which that organism typically interacts.
