Heredity Concept 1 Flashcard

Front

What is the correct genotypic ratio for this Punnett square?

Back

50% RR, 50% Rr

Front

What is the correct phenotypic ratio for the Punnett square?

Back

50% round, 50% wrinkled

Front

Round (R) is dominant to wrinkled (r). A plant that is homozygous dominant is crossed with a plant that is wrinkled. What are the parent genotypes?

Back

RR x rr

Front

Is Bb dominant or recessive?

Back

dominant

Front

Is bb dominant or recessive?

Back

recessive

Front

What is the genotype for wrinkled?

Back

rr

Front

Heterozygous is when...

Back

the alleles are different

Front

B = brown fur b = white fur In the punnett square, what is the probability for white fur?

Back

50% (2/4)

Front

B = brown eyes b = blue eyes What is true about these two brothers that have brown eyes? One has genotype BB the other Bb.

Back

they have same phenotype but different genotypes

Front
