What is a Trait
The expressed gene
A trait shown in grandparents that shows back up in grandchildren 1 out of 4 times
Yes it's recessive
Who was Gregor Mendel?
A scientist who discovered heredity
True or False chromosomes are made of DNA
True
What is an Allele
A version of a trait
When Mendel bred pea plants was the trait that showed up in the F1 generation recessive
No, it was dominant
How do organisms transfer genetic material?
Through alleles
What is the chance of a recessive gene showing up when two heterozygous organisms breed
1 in 4
What is the passing of physical characteristics from parent to offsprings?
Heredity
What did Mendel discover?
Recessive and dominant traits/genes/alleles
How do Alleles affect inheritance?
An organism's traits are controlled by the alleles it inherits from its parents. Some alleles are dominant, while others are recessive
How many alleles does a gene need to have to be considered to have multiple alleles
3+
What is a Punnet Square?
A chart that shows all possible ways alleles can combine in a genetic cross
If two peas breed and one is yellow and the other is green would it be recessive for a green F1 generation if it is then is it heterozygous or homozygous
No, Heterozygous
How are most traits inherited?
They are usually the result of complex patterns of inheritance
How many types of lipids are there and what are the types
2, saturated and unsaturated
What are Mendelian traits?
A characteristic passed from parents to offspring controlled by a single gene with two alleles, following predictable inheritance patterns
If a sponge is round and another is square and they mate would it be a recessive trait if it shows up as a square with round edges?
No, it would be codominant
Offspring inherit different forms of genes called __________ from each parent. Traits are affected by patterns of inheritance and interactions with the ___________
traits, environment
What is the difference between a heterozygous organism and a homozygous organism?
A heterozygous organism has two different alleles while a homozygous has two of the same alleles
