Genetics

What is a phenotype

• The genetic make up (code)

• The physical trait

Genotype refers to the ...

• physical expression of the genes

• the possible combination of alleles in a gene

• whether an allele is dominant or recessive

• how an organism will appear

having two of the same genes for the trait (sometimes called purebred).

• homozygous

• hetrozygous

• protein

• chromosome

having two different genes for a trait (sometimes called hybrid).

• protein

• homozygous

• heterozygous

• genotype

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

• GG

• Gg

• gg

• all of the choices result in yellow

What does heterozygous mean?

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

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

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

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

Incomplete dominance means that the traits are

• expressed equally

• dominant

• recessive

• blended

Which of the following is homozygous dominant?

• Yy

• Y

• yy

• YY

An allele whose trait only shows up when no dominant allele is present.

• hidden allele

• dominant allele

• recessive allele

• present allele

Who is considered the "father" of modern genetics?

• Einstein

• Mendel
