Reproduction
_____ is the passing of genes from parent to offspring
Heredity
The name of the gene that is primarily shown.
Dominant
In the presence of a dominant gene a ______ gene will never show.
recessive
Bb represents a heterzygous allel pair.
True
B is brown hair and b is blonde hair, if an offspring is heterozygous which hair color will they have?
Brown
The type of reproduction where the parent and offspring are the same.
Asexual.
BB means what?
BB is a homozygous dominant allel pair.
What is a punnett square.
A tool used to calculate the probability of an offspring receiving a certain trait.
An offspring has Bb so the recessive trait will show.
False
What do the capital letters represent in an allel pair?
Dominant gene
______ reproduction takes half of each of the parent's genes to create an offspring
sexual
If there is a 75% chance that an offspring will get straight hair (a dominant trait) what allel pairs do the parents have?
BB and Bb
What is the difference between sexual and asexual reproduction?
Sexual involves two organisms passes traits from both organisms onto offspring while asexual creates another identical offspring.
Both parents have BB so the offspring has a 100% chance of inheriting the dominant gene.
True.
A mother has Bb and a father has bb what would the punnett square boxes be filled with?
Bb, Bb, Bb, bb
Because it allows for evolution and adaptation over time.
That both parents are heterozygous for brwon eyes.
What's the difference between homozygous and heterozygous.
Both parents of an offspring are heterozygous for hair color brown or red (red being recessive), this mean the offspring has a 50% chance to of having red hair.
False
The mother of an offspring has BB while the father has Bb, B is brown eyes and b is blue eyes what is the probability that the offspring will have Homozygous Brown eye pair.
50%
What causes identical twins?
After reproduction the fertilized egg undergoes mitosis splitting itself into two identical egg cells.
If a mother has bb father has Bb, where B is dominant straight hair and b is recessive curly hair, what percent chance is the offspring going to have curly hair.
50%
How are phenotype and genotype related?
Phenotype is what shows and genotype is the gene code from parents.
A recessive gene only shows if there is no dominant present
True
The phenotype of an offspring is brown eyes, what kind of gene did they get?
Dominant
