Crazy Critters can have a T (elephant) or a t (mouse) for its type of ears. These are the __________ that are possible for the gene that codes for ears.
_____________ are passed down from parent to offspring.
If present, this allele always shows up in the offspring.
If both parents had a Tt for each trait, how would the offspring appear? Complete a Punnett square on your own paper to find the answer.
What shows the combination of alleles (example: TT) carried by an organism?
Words that describe traits (example: long tail) that appear are __________.
If both parents carry a Tt for a trait, what are the chances the offspring will have tt? Complete a Punnett Square on your own paper to determine the answer.
If both parents have a Tt, what are the chances the offspring will have the same genotype as the parents? Complete a Punnett square on your own paper to find the answer.
What are the chances that Mr. and Mrs. Smith will have a boy?
Which genotype represents a female?
If T=red and t=blue, could two red critters ever produce a blue critter?
Can a TT parent and a Tt parent ever produce a tt offspring? Complete a Punnett square on your own paper to find the answer.
Does a Punnett square tell exactly what would happen if parents had four offspring?
If a TT parent mated with a tt parent, what is the probability of the offspring having the dominant phenotype? Complete a Punnett square on your own paper to find the answer.
