Mendellian and Non-medellian Genetic Inheritance Patterns

Why do we use punnett squares?

They are effective to predict offspring caracteristics

What are two strategies/techniques to predict the genotypes of offspring?

Punnett squares and foiling

What is this an example of?

Incomplete dominance

How do you denote incomplete dominance in the genotype?

With two capital letters for the alleles

What inheritance pattern is this?

Codominance

Do linked traits change the probability of inheritance?

Yes, because they are connected and assorted via dependent assortment

Which individuals are predisposed to sex linked traits?

XY individuals

Can males (XY) be carriers of sex link traits?

No

What happens when genetic material is separated unequally in Meiosis I?

Homologous chromosomes don’t separate evenly meaning daughter cells are aneuploid and don’t have the same n

What happens when genetic material is separated unequally in Meiosis II?

Sister chromatids separate incorrectly meaning half the daughter cells are correct and haploid while the others are aneuploid

How can you use probability in genetics?

If traits are independent (on separate chromosomes) we can find the probability that they will be passed down

How do we calculate the probability of a particular outcome?

Divide the number of possible ways to get that outcome by the total number of events

What is the addition rule?

Add probabilities together to get the total probability of two or more mutually exclusive options

What is the multiplication rule?

Multiply probabilities together to get the total probability of two or more independent events occuring
