Heredity Flashcard Study Guide

Front

What type of mutations can cause cancers?

Back

Harmful mutations.

Front

What is a mathematical model that predicts the probability of possible genotypes and phenotypes?

Back

Punnett square.

Front

What is a form of a gene that is expressed only when a dominant allele is not present?

Back

Recessive.

Front

In a Punnett square, what must the genotype of the missing parent be if one parent is Bb?

Back

Bb.

Front

What are examples of genotypes?

Back

Aa, DD, bB, yy.

Front

What is the definition of a genotype?

Back

The genetic constitution of an individual.

Front

What is the definition of a phenotype?

Back

The observable characteristics of an individual.

Front

What does a dominant allele do in the presence of a recessive allele?

Back

It masks the expression of the recessive allele.

Front

What is the purpose of a Punnett square in genetics?

Back

To predict the genetic outcomes of a cross.

Front

What is the difference between a genotype and a phenotype?

Back

Genotype refers to the genetic makeup, while phenotype refers to the physical expression.
