tails, what would be the chance that you would flip
heads on the 11th toss?

Probability
Probability - 400 answer
The principle of probability can be used to
a) Predict the traits of the offspring produced by
genetic crosses
b) Determine the actual outcomes of genetic crosses
c) Predict the traits of the parents used in genetic
crosses
d) Decide which organisms are best to use in genetic
crosses
Probability - 400 question
A) Predict the traits of the offspring
produced by genetic crosses
Probability - 500 answer
The principle of segregation states that the 2 alleles
(mom and dad information) must split so that each
copy carries only a single copy of each gene in which
gamete making process…

Beyond Dominant & Recessive - 100
answer
What principal states that during gamete formation,
genes for different traits separate without influencing
each other's inheritance
(results in the mixing and matching of traits, therefore
dominant alleles aren’t always stuck with dominant
and vice versa)
Beyond Dominant & Recessive - 100
question
Principal of Independent Assortment
Beyond Dominant & Recessive - 200
answer
The pattern of inheritance that there are more than 2
variations of a trait
(ex: green eyes, blue eyes, hazel eyes, brown eyes)
