7A
These are long molecules of DNA coiled around proteins, carrying genetic information.
What are chromosomes?
This is the type of cell division that produces gametes with half the chromosome number of the parent cell.
What is meiosis?
The observable physical or biochemical characteristics of an organism.
What is the phenotype?
Epigenetics involves changes in gene expression without changes to this.
What is genotype?
This student's middle name is the longest in the class, and also the same number of letters as their first and last names combined.
Who is Joanna?
This term describes different forms of the same gene, found at the same locus on homologous chromosomes.
What are alleles?
The process during Prophase I where homologous chromosomes pair up and exchange genetic material.
What is crossing over?
The genetic makeup of an organism, including the alleles it carries.
What is the genotype?
This epigenetic mechanism involves the addition of a methyl group to DNA, often silencing gene expression.
What is DNA methylation?
This student's middle name is also the name of a city in Australia.
Who is Abi?
The complete set of genetic material in an organism.
What are genomes?
The number of daughter cells produced by meiosis and their chromosome number relative to the parent.
What are 4 haploid cells?
An organism with two identical alleles for a particular gene.
What is homozygous?
This affects the tightness that DNA is coiled around histones, creating easier access for transciption.
What is acetylisation?
This student has no middle name.
Who is Laura?
A genetic abnormality where an organism has one extra chromosome?
What is trisomy?
This event during Metaphase I increases genetic variation by randomly aligning homologous chromosome pairs.
What is independent assortment?
In a heterozygous individual, this allele determines the phenotype.
What is the dominant allele?
Epigenetic changes can be inherited. That means they can sometimes be passed on through this.
What is cell division or gametes?
These two students share a middle name.
Who are Atarah and Bella?
A visual representation of an individual's entire genome ordered into homologous pairs.
What is a karyotype?
The amount of DNA in the daughter cells compared to the amount of DNA in the cell undergoing metaphase I.
What is a quarter?
A pattern of inheritance where both alleles from the genotype pf a heterozygous individual are dominant and expressed in the phenotype of that organism.
What is codominance?
The amount of phenotypic variance that can be explained by genes in a given population.
This student had the best middle name (according to the loudest people in the room).
Who is Julian?
