Punnett Squares
What is the phenotype of an organism? Give an example.
What is "physical appearance, eye color (etc.)"?
Define mutation.
What is "any change in DNA sequence that affects genetic information"?
How many PAIRS of chromosomes do humans typically have?
What is "23"?
The basic structural and functional unit of living organisms are called _______.
What are "cells"?
One form of a gene from a gene pair is known as _______.
What is an "allele"?
What is the genotype of an organism? Give an example.
Give an example of a cause of mutations.
What is "environmental exposure, inheritance, spontaneous occurrence"?
Many plants will grow from cuttings. The cutting develops a new root system and becomes a clone of the parent plant, but an independent new plant. What is the type of asexual reproduction called?
What is "vegetative propagation"?
The stronger trait in genetics that shows if present and represented by a capital letter.
What is "dominant"?
What is the role of DNA molecules in cells?
What is "provide instructions for making proteins"?
Create a punnett square to cross two heterozygous parents. What is the probability of heterozygous offspring?
Give an example of 1 helpful and 1 harmful mutation.
What is "(there are multiple answers - be able to justify if needed)"?
Lizards can regrow their tails. Starfish can regrow their arms when cut apart. What type of asexual reproduction is this?
What is "regeneration"?
The passing of traits from on generation to another is known as __________.
What is "Heredity/Inheritance"?
What is "Thymine, Cytosine"?
What is "25%"?
What causes an immediate result of gene mutation in an organism?
What is "a change in a protein produced by the organism"?
A form of asexual reproduction that results from the outgrowth of a part of a cell or body region leading to a separation from the original organism into two individuals? (Yeast produce this way)
What is "budding"?
The weaker gene in genetics, requires a homozygous form to appear, represented by a lowercase letter.
The sequence of ________ in a DNA molecule determines the protein that will be produced.
What is "nucleotides"?
B = brown eyes b =green eyes
A mom has a heterozygous genotype. One of her daughters has a homozygous dominant genotype. What do they have in common? What do they have that is different? (in terms of phenotype and genotype)
What is "same - phenotype (brown eyes), different - genotype"?
A parent has mutations in skin cells from excessive sun exposure. Will the parent's offspring inherit this mutation? Why or why not?
What is "no - skin cells are not gametes"?
Some one-celled organisms have the ability to replicate their nucleus and split in half, making two new cells. What is this type of asexual reproduction called?
What is "binary fission"?
Structure found in nucleus that contains DNA.
What is "chromosome"?
What is the difference between asexual and sexual reproduction?
What is "sexual - produces genetically similar offspring and requires sperm and egg. asexual - produces genetically identical offspring and requires only one parent"?
