EOC Blitz Review - Inheritance and Classical Genetics

Front

What is colorblindness?

Back

Colorblindness is a recessive, X chromosome sex-linked disorder that affects the ability to distinguish certain colors.

Front

What percentage of offspring will be colorblind if one parent is a carrier and the other is colorblind?

Back

50% of the offspring will be colorblind.

Front

What is co-dominance in genetics?

Back

Co-dominance is an inheritance pattern where both traits are fully expressed in the offspring.

Front

What is the difference between homozygous and heterozygous genotypes?

Back

Homozygous genotypes have two identical alleles (e.g., TT), while heterozygous genotypes have two different alleles (e.g., Gg).

Front

What do genes code for?

Back

Genes code for proteins, which are essential for various functions in the body.

Front

What is the genotype for a homozygous dominant individual?

Back

The genotype for a homozygous dominant individual is represented as 'AA'.

Front

What is the genotype for a heterozygous individual?

Back

The genotype for a heterozygous individual is represented as 'Aa'.

Front

What is the phenotypic ratio in a monohybrid cross?

Back

The phenotypic ratio in a monohybrid cross is typically 3:1.

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genotypes and phenotypes of offspring from genetic crosses.

Front

What is the significance of the X chromosome in sex-linked traits?

Back

The X chromosome carries genes that can cause sex-linked traits, which are often expressed differently in males and females.
