Mendelian Genetics

Front

What is co-dominance in genetics?

Back

Co-dominance is a type of inheritance pattern where both traits from the parents are fully expressed in the offspring.

Front

What are alleles?

Back

Alleles are different forms of a gene that determine specific traits, with one allele inherited from each parent.

Front

What is the probability of a blue-eyed baby from two brown-eyed parents (Bb)?

Back

The probability is 25%.

Front

If green is dominant over purple, what is the genotype of a purple pea plant?

Back

The genotype of a purple pea plant is gg.

Front

What is the dominant trait in a Punnett square showing yellow and green pea seeds?

Back

The dominant trait is yellow pea seeds.

Front

Define complete dominance.

Back

Complete dominance occurs when one allele completely masks the effect of another allele in a heterozygous condition.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic situation where one allele does not completely dominate another, resulting in a blended phenotype.

Front

What is a Punnett square used for?

Back

A Punnett square is a diagram used to predict the outcome of a genetic cross by showing the possible combinations of alleles.

Front

What does homozygous mean?

Back

Homozygous refers to having two identical alleles for a particular gene.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene.
