Genetics

Why do you think Gregor Mendel is the father of genetics?

• because he discovered DNA

• because he discovered the X and Y chromosome

• because of his experiments with pea plants, and he discovered the laws of inheritance

How is an allele different from a gene?

• a gene is the expression of traits (hair) and the allele determines the variation in that trait (blonde, brown, etc...)

• a allele is the expression of traits (hair) and the gene determines the variation in that trait (blonde, brown, etc...)

How can you tell if a genotype is heterozygous or homozygous?

• heterozygous have different letters and homozygous have the same letters

• heterozygous have identical letters and homozygous have the different

• They are both the same and there is no difference

• one is longer than the other

Who is the Father of Genetics?

• Mendelev

• Rutherford

• Gregor Mendel

• Mr. Hopkins

What is a heterozygous genotype?

• two dominant genes

• two different genotypes

• two identical genotypes

What is a homozygous genotype?

• one dominant gene and one recessive gene

• two different genotypes

• two identical genotypes

Who discovered the laws of inheritance?

• McGrath

• Mendel

• Punnett

• Hopkins

Why will these both inherit the dominant trait?

• because they want to

• because they do not have any recessive genes

• because they both have dominant genes that will over take any recessive genes

Genetics is...

• the study of how traits are inherited through the actions of alleles

• the study of how plants create their own food

• the study of biology and the interactions of animals

• the study of how traits are predetermined based on your parents traits.

What is a genotype?

• the dominant genes

• the recessive genes

• a code for the pair of genes an organism has (Bb, BB, bb)

• the traits that are expressed by your genetic code
