Question

in heterozygous individuals, the ______ allele is not expressed *

• recessive
• dominant
• phenotype
• genotype

in heterozygous individuals, the ______ allele is expressed *

• genotype
• dominant
• recessive
• phenotype

a ______ square allows you to determine the expected patterns of different genotypes in the offspring of two parents.

• four
• punnett
• tic-tac-toe
• punness

Explanation:

Analyze the first question

Using the Dominant and Recessive knowledge point

In heterozygous individuals (who carry two different alleles for a single gene, such as \(Aa\)), the allele that is masked and not expressed in the phenotype is the recessive allele.

Analyze the second question

Using the Dominant and Recessive knowledge point

In heterozygous individuals, the allele that is fully expressed and determines the organism's appearance is the dominant allele.

Analyze the third question

Using the Punnett Square knowledge point

A Punnett square is a graphical representation used to calculate and predict the probability of different genotypes and phenotypes in the offspring of two parents.
