Genetics Review

Front

What is the genotype of a shaggy fur animal if shaggy fur is dominant to short fur?

Back

The genotype can be either homozygous dominant (FF) or heterozygous (Ff).

Front

What is the genotype of a short fur animal if shaggy fur is dominant to short fur?

Back

The genotype must be homozygous recessive (ff).

Front

Define homozygous in genetics.

Back

Having two identical alleles for a specific trait (e.g., FF or ff).

Front

Define heterozygous in genetics.

Back

Having two different alleles for a specific trait (e.g., Ff).

Front

How many alleles does an offspring receive from each parent for a specific trait?

Back

One allele from each parent, totaling two alleles.

Front

What type of inheritance occurs when two alleles blend together?

Back

Incomplete Dominance.

Front

What is co-dominance in genetics?

Back

A situation where both alleles in a heterozygote are fully expressed, resulting in a phenotype that is neither dominant nor recessive.

Front

What are phenotype percentages?

Back

The proportion of different physical traits expressed in the offspring.

Front

If a brown fur animal (A) is crossed with a white fur animal (a), what are the possible genotypes of the offspring?

Back

The possible genotypes are Aa (brown fur) and aa (white fur).

Front

What is a Punnett Square used for?

Back

To predict the genotypes and phenotypes of offspring from a genetic cross.
