Asexual
Reproduction of a single cell by dividing into two parts.
Binary Fission
A gene editing tool that can add, remove, or alter DNA.
CRISPR
Dominant traits.
Three tigers have different parents. They all have the same protein for stripe pattern in their cells. What can you say about the tiger's stripe patterns?
They will have the same stripe patterns since their proteins for stripe patterns are the same so the proteins will connect the same way.
Type of reproduction that mixes DNA to create a unique offspring
Sexual Reproduction
Growth or bud forms on the parent and breaks off when big enough.
Budding
A change in a DNA sequence.
Mutation
Squares represent males, and circles represent females. Based on the chart, who is mostly affected by this trait?
Males
Two goldfish have different parents. One fish has a split tail and the other does not. Why do the goldfish have tails with different shapes?
The goldfish have different versions of the gene for tail shape, which instruct for different proteins that connect in different ways to make different tail shapes.
Asexual
Reproduction found in plants where new plants are formed without the production of seeds. Some plants can produce little plantlets or some grow new plants out of runners.
Vegetative propagation
A molecule that codes for proteins and creates genes.
DNA
Pedigree charts show how genetic mutations and traits are passed down from different ____________ in a family.
Generations
A young goat has down-ward curved horns. Its father has upward curved horns while its mother has downward curved horns. Why does the young goat have downward-curved horns?
The young goat inherited its copies of the genes for horn shape from its mother and not from its father. Those genes connect together to make its downward-curved horns.
Creates genetic variation in a species, which can increase the odds of surviving in a change in environment.
Sexual Reproduction
Reproduction where a new organism grows from a fragment or piece of the parent.
Fragmentation
The process of altering or changing DNA
Sexual
Two rabbits have different parents. One rabbit has ears that flop over, and the other rabbit has ears that stand straight up. Why do rabbits have ears with different shapes?
Different versions of the trait, which instruct different proteins that make different ear shapes.
Is much quicker and produces many offsprings.
Asexual Reproduction
An unfertilized egg develops into a new individual.
Parthenogenesis
Name 2 neutral mutations.
Attached or detached earlobes, color blindness, two different eye colors.
What is the probability of having (B) brown hair?
50%
A father- curly wool
Mother- Straight wool
What happened to the offspring?
