Understanding Alleles and Traits

The video tutorial explains what alleles are, how they are another name for specific genes, and how they determine traits. It covers the classification of alleles into dominant and recessive, using letters to represent them. The tutorial also discusses the combinations of alleles, such as homozygous dominant, homozygous recessive, and heterozygous, and how these combinations affect traits. Examples using rabbits illustrate these concepts.

What is another name for a gene?

• DNA

• Trait

• Allele

• Chromosome

How are alleles related to traits?

• They are unrelated

• Alleles are only for invisible traits

• Alleles determine visible and invisible traits

• Alleles are only for visible traits

How can we represent alleles using letters?

• Using symbols

• Using colors

• Using capital and lowercase letters

• Using numbers

What does a capital letter represent in allele notation?

• A recessive trait

• A dominant trait

• A neutral trait

• An unknown trait

Which of the following is a combination of alleles?

• Two dominant alleles

• Two invisible alleles

• Two neutral alleles

• Two unknown alleles

What is a homozygous dominant combination?

• Two recessive alleles

• One neutral and one recessive allele

• One dominant and one recessive allele

• Two dominant alleles

What is a heterozygous combination?

• One dominant and one recessive allele

• Two recessive alleles

• Two neutral alleles

• Two dominant alleles

What trait will a heterozygous individual show?

• Dominant trait

• Recessive trait

• Neutral trait

• Invisible trait

What makes predicting trait combinations complex?

• The number of chromosomes and traits

• The uniformity of alleles

• The simplicity of genetic traits

• The lack of alleles

What do you inherit from your parents that determines your traits?

• DNA

• Proteins

• Alleles

• Chromosomes
