A purebred chicken with white feathers is crossed with a purebred chicken that has black feathers. Each of their offspring has both black and white feathers. Why does this happen?
Both alleles for feather color are dominant.
Both alleles for feather color are recessive.
The alleles for feather color are neither dominant nor recessive.
Several alleles work together to determine the trait.
What is the chromosome theory of inheritance?
Chromosomes are carried from parents to offspring on hybrids.
Genes are carried from parents to offspring on chromosomes.
Hybrid pairs of chromosomes combine to form offspring.
Codominant genes combine to form new hybrids.
What happens during meiosis?
Two sex cells combine.
Chromosome pairs separate and are distributed into new sex cells.
Each sex cell copies itself to form four new chromosomes.
Chromosome pairs remain together when new sex cells are formed.
Which term refers to physical characteristics that are studied in genetics?
traits
offspring
generations
hybrids
