Actual physical appearance

Front

In certain rats, black fur is dominant over white. Two heterozygous rats have offspring with:

Back

three different genotypes and two different colors.

Front

A red female bird and a red male bird produced golden offspring. How could the offspring inherit a trait not shown in either parent?

Back

Both parents carried a recessive gene for the golden color and passed it on to their offspring.

Front

Mom has brown eyes (Bb), you have brown eyes (BB). What traits must dad have for you to be homozygous?

Back

Brown eyes

Front

Punnett square is used to…

Back

determine the probability of offspring traits

Front

Cross of pea plants: HH (yellow) x hh (green) yields yellow seeds. True statement?

Back

The allele H is dominant over the allele h for seed color.

Front

Green seed pea and yellow seed pea plants produce offspring with all yellow seeds. Reason?

Back

The genes from the yellow-seeded parent were dominant.

Front

Genotype definition?

Back

Genes in DNA responsible for a trait.

Front

Characteristic passed to offspring through genes.

Back

Trait

Front

Father's genotype: TT, Mother's genotype: Tt. Offspring description?

Back

All offspring have the same phenotype, but different genotypes.
