FLASHCARD QUESTION
Front
Back
tt
Answer explanation
In the Punnett square, the combination of two short alleles (tt) results in a short phenotype. Since both parents contribute a 't', the missing square must be 'tt', indicating both alleles are short.

FLASHCARD QUESTION
Front
Genotype for a yellow plant (G = green, g = yellow)
Back
gg
Answer explanation
The genotype for a yellow plant is 'gg' because yellow is represented by the recessive allele 'g'. The dominant allele 'G' produces green plants, so only 'gg' results in yellow.

FLASHCARD QUESTION
Front
B = brown fur b = white fur In the punnett square, what is the probability for white fur?
Back
50%
Answer explanation
In a Punnett square for a cross between brown (B) and white (b) fur, the possible genotypes are BB, Bb, Bb, and bb. The white fur genotype (bb) appears once out of four, giving a probability of 50% for white fur.

FLASHCARD QUESTION
Front
Aa, DD, bB, yy are all examples of
Back
genotypes
Answer explanation
Aa, DD, bB, and yy represent combinations of alleles, which define the genetic makeup of an organism. Therefore, they are examples of genotypes, not phenotypes, which refer to observable traits.

FLASHCARD QUESTION
Front
What you see, or the physical appearance.
Back
Phenotype
Answer explanation
The term 'phenotype' refers to the observable physical appearance of an organism, which aligns with the description given in the question. 'Homozygous' relates to genetic makeup, not appearance.

FLASHCARD QUESTION
Front
AA and Aa always show up as
Back
dominant
Answer explanation
AA and Aa both contain at least one dominant allele (A), which is why they always show up as dominant in phenotypic expression.

FLASHCARD QUESTION
Front
Each one of the boxes on the Punnett Square represents what probability of an offspring's genotype?
Back
25%
Answer explanation
Each box in a Punnett Square represents a possible genotype of the offspring. With two heterozygous parents, there are four combinations, making the probability of each genotype 25%.
