Front

Heterozygous: Organism with different genes for a trait (Tt)

Back

An organism that has different genes for a trait (Tt)

Answer explanation

Heterozygous organisms have both dominant and recessive alleles in their genotype, two different sized letters/alleles

Front

Heterozygous yellow pea plant genotype:

Back

Yy

Answer explanation

Hetero means different. Heterozygous means two different alleles or two different cases/size of letter

Front

Phenotype example:

Back

red hair

Answer explanation

Phenotypes are the physical trait you can see.

Front

Phenotype for Tt (T = tall, t = short)

Back

tall

Front

Capital letter represents which allele?

Back

Dominant Allele

Answer explanation

Dominant traits are represented by capital letters because they always show

Front

Green is dominant over purple. Genotype?

Back

gg

Answer explanation

The monster is purple, so since green is dominant (G), the only combination it can be is (gg) because that is the only case a recessive trait will show. You have to have two alleles so it has to be (gg) or homozygous recessive.

Front

In pea plants, the tall allele is dominant to the short allele. Key:

Back

Tall = T, Short = t

Front

Homozygous recessive?

Back

rr

Answer explanation

Homozygous=Both alleles are same size letters

Recessive= lowercase letter

Front

Homozygous dominant genotype?

Back

HH

Answer explanation

Homozygous=same size alleles/letters

Dominant=Capital letters

Front

Genotype definition

Back

Combination of alleles (letters) an organism has.

Answer explanation

genotype refers to the actual genes an organism has.These are called the alleles and are represented by letters. Examples: AA, Uu, Jj, RR, vv, Mm
