0%
Bingo Square #10
________ is the passing down of traits from one generation to the next?
Hereditary
Bingo Square #15
some genes can be hidden or covered up by another. these are considered to be-
recessive
Bingo Square #6
how are traits passed from parent to offspring
genes during reproduction
Bingo Square #4
Create a Punnett Square for the following:
D=hearing
d=deafness
In dogs, there is a hereditary type of deafness caused by a recessive gene. Two dogs who carry the gene for deafness but have normal hearing are mated. What are the possible genotypes, phenotypes of their offspring and the probability for each?
Genotypes: DD, Dd, dd
Phenotypes: hearing, deafness
Probability: 75% hearing, 25% deafness
Bingo Square #20
B=brown eyes
b= blue eyes
Mike has heterozygous for brown eyes. Margie has blue eyes homozygous recessive. What are the percentages for both phenotypes?
50% brown and 50% blue
Bingo Square #2
Alleles that are the same are called _______?
Homozygous
Bingo Square # 1
what are Punnett Squares used for
to determine the outcome of genetic crossings (probability of genotypes and phenotypes)
Bingo Square #22
Do a Punnett Square and calculate the genotype and phenotype RATIOs of the following cross. Both parents are heterozygous for Ff.
F=not webbed fingers
f= webbed fingers
Genotype: FF, Ff, Ff, ff so = 1:2:1 genotype ratio
Phenotype: FF is not webbed, Ff is not webbed, Ff is not webbed, and ff IS webbed. SO, the phenotype ratio is: 3:1
Bingo Square #7
Which of the following genotypes are hybrids?
BB, Mm, BB, Xx, Aa, KK
Mm, Xx, Aa
The alleles are different (heterozygous/hybrid)
Bingo Square 21
Mike is heterozygous for brown eyes (Bb). His wife has blue eyes (bb). What percentage of their children will most likely have brown eyes and blue eyes?
What is 50% brown and 50% blue eyes?
Bingo Square #12
Alleles that are different are called ________?
Heterozygous
Bingo Square #3
W=widow's peak
w=no widow's peak
Do the Punnett Square for the following genotypes:
Ww dad mates with ww mom.
Determine the genotype AND phenotype probability of their possible offspring.
50% Ww and 50% ww Genotype
50% of the offspring will possibly have a widow's peak and 50% of the offspring may not have a widow's pea k (phenotype)
Bingo Square #19
why does a Punnett square use capital and lowercase letters
capitial = dominant trait lower case= recessive trait
Bingo Square #11
Which of the following genotypes are considered purebreds/homozygous?
Ee, YY, Pp, Dd, LL
YY, LL
Both alleles are the same, therefore are purebreds/homozygous for that trait.

_________ describes alleles and is represented by letters like Tt or TT
Genotype
Bingo Square #18
Do a Punnett Square
