Part of Gregor Mendel's hypotheses of inheritance proposed that when two contrasting traits occur together, one them may be completely expressed, while the other may have no observable effect on the organisms appearance. He called the expressed trait dominant and the unexpressed trait recessive. In his genetic experiments, mendel studied seven contrasting traits of peas. One of the traits he studied was the trait for seed shape--wrinkled and round. In an experiment to determine which form of this trait was dominant, Mendel performed the following experiment

What factors contribute to the effect an environmental toxin has on the human body?

Kara has a plant that produces either purple or white flowers. she crosses a plant that has two recessive alleles for white flowers with a plant that has two dominant alleles for purple flowers. which result would be true of all of the offspring? a) all of the offspring would have two recessive alleles and white flowers. b) all of the offspring would have two dominant alleles and purple flowers. c) all of the offspring would have one recessive allele, one dominant allele, and white flowers. d) all of the offspring would have one recessive allele, one dominant allele, and purple flowers

Look at the inheritance patterns. what do you notice? can a single offspring inherit both chromosomes from one parent?
