| 🇬🇧 | 🇬🇧 |
| What are 2 types of cell division in animals? | Mitosis and Meiosis. |
| What are the daughter cells produced by Mitosis called? | Diploid cells. |
| What are the daughter cells produced by Meiosos called? | Haploid Cells. |
| How many chromosomes do diploid cells have? | 46 chromosomes each (23 pairs) |
| True/false: Haploid cells have 22 chromosomes each. | False - They have 23 each |
| Why does Meiosis produce 4 daughter cells? | Because there are 2 divisions |
| What are the 6 stages of Mitosis? | Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis |
| What happens during prophase? | A cells genetic DNA condenses |
| What happens in the interphase? | The cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. |
| What happens during Metaphase? | The duplicated chromosomes line up and spindle fibers connect to the centromeres. |
| What happens in the prophase? | The cell breaks down some structures and builds others up, setting the stage for division of the chromosomes and the chromosomes begin condensing. |
| What happens during Anaphase? | Sister chromatids separate and move toward the centrioles. |
| What happens in telophase? | Chromosomes begin to unwind and the nuclear envelope reforms. |
| What happens during Cytokinesis in animal cells? | The cell membrane draws in and pinches off. |
| What happens during Cytokinesis in plant cells? | A cell plate forms followed by a new cell membrane |
| What type of cell division does the image depict? | The graph depicts the process of meiosis. The amount of DNA in each nucleus at the conclusion of the process is half of the amount of DNA that was present in the parent cell prior to DNA replication. |
| What happens in Prophase II? | Chromosomes condense and the nuclear envelope breaks down, if needed. The centrosomes move apart, the spindle forms between them, and the spindle microtubules begin to capture chromosomes. |
| Is the genetic condition shown in the below pedigree caused by a recessive allele or a dominant allele? | Recessive allele; children do not have the condition. |
| What happens in Metaphase II? | The chromosomes condense and become distinguishable as they align along the metaphase plate through the facilitation of the spindle fibers in the center of the dividing cell. |
| What happens in Anaphase II? | The stage when sister chromatids of every chromosome separate and begin to move towards the opposite ends of the cell |
| What happens in Telophase II? | Nuclear membranes form around each set of chromosomes, and the chromosomes decondense. |
| What happens in the final stage of meiosis? | Cytokinesis splits the chromosome sets into new cells, forming the final products of meiosis: four haploid cells in which each chromosome has just one chromatid. |
| What type of diagram is this? | It is a Bohr Diagram. |
| What are the daughter cells produced by Meiosos called? | Haploid cells. |
| How many chromosomes do diploid cells have? | 46 chromosomes each (23 pairs). |
| True/false: Haploid cells have 22 chromosomes each. | False - they have 23 each. |
| Why does Meiosis produce 4 daughter cells? | Because there are 2 divisions. |
| What are genetics? | The study of how traits are passed from parent to offspring |
| What is the name for the structure of DNA? | Double-helix. |
| What is the basic hereditary unit that carries the instructions to make a particular protein called? | Gene. |
| What is commonly used to determine the phenotypes of the childern using the genotypes of the parents? | A Punnet Square. |
| Why can't a red-head be heterozygous for the condition? | Because a recessive allele will only be expressed in an individual if they have a homozygous genotype. |
| What are the 4 types of inheritance? | Simple Inheritance; Incomplete Inheritance; Co-Domination; Sex-linked Inheritance. |
| What is the full form of DNA | Deoxyribonucleic Acid |
| What is a building block consisting of a sugar group, a phosphate group, and a nitrogen base called? | A nucleotide. |
| Cells use amino acids to make _______ _________. | Protein molecules. |
| What is the disease in which the individual has an extra chromosome (number 21)? | Tri-21 (Down Syndrome). |
| What are body cells called? | Somatic cells. |
| What are sex cells called? | Gametes. |
| What only pairs with Thymine (T)? | Adenine (A). |
| What only pairs with Guanine (G)? | Cytosine (C). |
| What are the 'rungs' of DNA made up of? | The 4 nitrogen bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). |
| What are the 'rails' of DNA made up of? | Sugar and Phosphate. |
| What is the sugar in DNA? | Deoxyribose. |
| Somatic cells are _______. | Diploid. |
| Gametes are _______ | Haploid. |
| Chromosome pairs of the same length, centromere position, and staining pattern, with genes in the same loci are called what? | Homologous pairs. |
| Where are chromosomes located? | In the nucleus of a cell. |
| Where are genes located? | On the chromosomes. |
| Where are 2 identical copies of the chromosome located? | At the centromere. |
| Who is the "father of modern genetics"? | Gregor Mendel. |
| What is it called when A bonds to T and C to G? | Base pairing. |
| What is the type of inheritance that is gender-specific? | Sex-linked Inheritance. |
| Why would you expect half the children born in the world to be female? | Because there is a 50% chance that the sperm carries an X- or a Y-chromosome. |
| What is the probability of the offspring retracting a recessive gene (aa)? | 25%, 50% chance the offspring will retract a heterozygous dominant gene, 25% chance of it being homozygous dominant and 25% chance homozygous recessive. |
| Is the genetic condition shown in the below pedigree caused by a recessive allele or a dominant allele? | Recessive allele; children do not have the condition. |
| What is the behavioural perspective? | We are who we are/do what we do due to involuntary reactions to environmental stimuli, reinforcement of behaviors, and observing and imitating others |
| What is the psychoanalytic or psychodynamic perspective? | We are who we are/do what we do due to…bad or good childhood experiences and memories hidden in our subconscious |
| What is the cognitive perspective? | We are who we are/do what we do because we actively think about past and present and make predictions about our future as we interact with environment |
| What is the biological perspective? | We are who we are due to biological and physiological causes and their interactions with nurture factors |
| What is the evolutionary perspective? | We are who/how we are due to “survival of the fittest” interaction of our genes with our environment |
| What is the humanistic perspective? | Every human has a desire to achieve to his or her fullest potential; humanists look at environmental factors that are necessary to reach fullest potential and what prevents others from doing so |
| What is the sociocultural perspective? | We are who we are, do what we do due to…the culture in which we are raised and social expectations and norms |
| What are the two main types of conditioning? | Operant and Classical |
