Genetics and Probability Assessment

What is a genotype?

• The physical appearance of a trait
• The gene combination of two alleles for a trait
• The probability of inheriting a trait
• A tool for predicting offspring traits

In the genotype "Tt", what does each letter represent?

• Two different traits
• Two identical alleles
• One allele from each parent
• The same trait expressed twice

How is a genotype typically written?

• Using numbers and symbols
• Using two capital letters only
• Using two letters, either capital or lowercase
• Using one letter only

What is a phenotype?

• The physical expression of a trait
• The genetic makeup of an organism
• The probability of inheritance
• The process of genetic crossing

Which is an example of a phenotype?

• TT genotype
• Yellow color
• Punnett square
• Allele combination

How are genotype and phenotype related?

• They are the same thing
• Genotype determines phenotype
• Phenotype determines genotype
• They are completely unrelated

What is probability in genetics?

• The physical appearance of traits
• The genetic makeup of an organism
• The likelihood of a trait occurring
• The process of creating Punnett squares

What is the primary use of probability in genetics?

• To determine an organism's appearance
• To predict offspring traits
• To change genetic makeup
• To create new species

What is a Punnett square used for?

• Measuring genetic variation
• Calculating mutation rates
• Predicting offspring probabilities
• Determining parent genotypes only

What type of cross involves one trait?

• Dihybrid cross
• Monohybrid cross
• Multiple cross
• Complex cross
