What is a dominant allele?

A trait that is always shown (capital letter)

A trait that can be hidden (lower case letter)

What does heterozygous mean?

An organism that has different genes for a trait (Tt)

An organism that has the same genes for a trait (TT or tt)

When neither gene is fully dominant; offspring is a mixture of both

the different forms of a trait (hair color--> brown, blonde, red

Punnett squares can be used to predict the probability of:

having an inherited disease or a genetically determined physical trait

being exposed to a contagious disease and contracting it

What is the phenotype of the offspring? (A-Brown hair; a-blond hair)

75 % Brown Hair and 25% Blond Hair

50 % Brown Hair and 50% Blond Hair

25 % Brown Hair and 75% Blond Hair

0% Brown Hair and 100% Blond Hair

What does a Punnett Square do ?

predict genotypes and phenotypes in offspring

tell you exactly what your offspring will look like

increase the chance you pass on recessive traits

have no purpose but for Taylor to give us extra assignments

G = green, g = yellow The genotype for a yellow plant is...

all of the choices result in yellow

What is a punnett square?

graph used to predict the possible genotypes of offspring in a given cross

a graph used to predict the possible birth rate of offspring.

a graph used to predict the possible behavioral characteristics an offspring could have

Genotype refers to the ...

the possible combination of alleles in a gene

physical expression of the genes

whether an allele is dominant or recessive

A green pea plant (Gg) is crossed with a yellow pea plant (gg). Describe the genotype of the offspring. (Be sure to remember that the capital letter is dominant ).

50% heterozygous and 50% homozygous recessive

50% heterozygous and 25% homozygous recessive

25% heterozygous and 50% homozygous

A tall plant (TT) is crossed with a tall plant (Tt). What is the phenotype of the offspring?

50% homozygous dominant; 50% heterozygous; 100% tall

100% homozygous dominant; 100% tall

25% homozygous dominant; 75% heterozygous; 100% short

50% homozygous dominant; 50% heterozygous; 100% short

A tall plant (Tt) is crossed with a short plant (tt). What is the genotype of the offspring?

50% heterozygous; 50% homozygous dominant

25% heterozygous; 75% homozygous

A black chicken (BB) is crossed with a black chicken (BB). What is the genotype and phenotype of the offspring? Draw a Punnet square and naswer this question.

100% homozygous dominant; 100% black
