Front

What is the probability of an offspring having O blood when crossing an individual with A blood and an individual with B blood?

Back

1/4

Front

What are the phenotype percentages of the offspring when crossing A (Brown fur color) and a (White fur color)?

Back

75% Brown fur and 25% White fur

Front

In a heterozygous genotype, which allele takes over in the phenotype?

Back

Dominant

Front

What is the probability of producing a white (WW) cow when a roan (RW) bull mates with a red (RR) cow?

Back

0%

Front

What fraction of the offspring will have wrinkled, green seeds based on the given Punnett square?

Back

1/16

Front

Define phenotype.

Back

The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.

Front

Define genotype.

Back

The genetic constitution of an individual, often represented by letters (e.g., AA, Aa, aa).

Front

What is a Punnett square used for?

Back

To predict the genotypes of offspring from a genetic cross.

Front

What does a dominant allele do in a genetic cross?

Back

It masks the effect of a recessive allele in the phenotype.

Front

What is the expected phenotype ratio for a monohybrid cross?

Back

3:1 for dominant to recessive traits.
