_____ Pseudogenes may have some gene-like features such as a promoter and splice sites. _____ Pseudogenes encode proteins, but the translated proteins are non-functional. _____ Pseudogenes can provide insight into the evolutionary history of the related functional gene. _____ Every pseudogene has a similar DNA sequence to some functional gene. _____ All pseudogene pretent to transcribe other genes when they only transcribe one type of genetic information.
What do we mean when we use the terms monohybrid cross and dihybrid cross?
A) A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents. B) A dihybrid cross involves organisms that are heterozygous for two characters that are being studied, and a monohybrid cross involves organisms that are heterozygous for only one character being studied. C) A monohybrid cross is performed for one generation, whereas a dihybrid cross is performed for two generations. D) A monohybrid cross results in a 9:3:3:1 ratio whereas a dihybrid cross gives a 3:1 ratio.
