Front

TRUE or FALSE: X^T X^t is an example of a genotype.

Back

TRUE

Front

What are the possible genotypes in the F1 offspring when crossing a heterozygous parent (Mm) with a homozygous dominant parent (MM)?

Back

MM and Mm

Front

What are the possible genotypes in the F1 offspring when crossing a heterozygous parent (Dd) with a homozygous recessive parent (dd)?

Back

Dd and dd

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genotypes of offspring from a genetic cross.

Front

What are the blood types of parents if the offspring can have type A blood?

Back

The parents' blood types could be Type A and Type AB.

Front

Define homozygous dominant.

Back

Homozygous dominant refers to having two identical dominant alleles for a trait (e.g., MM).

Front

Define heterozygous.

Back

Heterozygous refers to having two different alleles for a trait (e.g., Mm).

Front

What is the significance of recessive traits?

Back

Recessive traits only manifest in the phenotype if an individual has two recessive alleles (e.g., tt).
