Aplant can produce either purple flowers or white flowers. what is the probability of purple-flowered offspring if two plants that are heterozygous for purple flowers are crossed?

A heterozygous trait contains two different allelic forms of a gene in which one is a dominant allele and one is recessive allele. If there is a crossing between two plants that are heterozygous for their trait then the probability of expression of the dominant allele is 3/4.

So according to this question plants are heterozygous that means the genes would be like Pp and Pp. Here P indicates the purple color allele which is dominant and p indicates recessive white color allele.

Therefore cross between these two will give genotypes PP, Pp Pp, and pp. So according to the law of dominance that says dominant allele will express itself, therefore, probability of purple-flowered offspring is 3/4 because 3 out of four genotypes have the dominant allele.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
