44) A gene is recognized as being non-Mendelian in heredity trend in the event it generally seems to “violate” Mendel’s statutes. Which of your own following might possibly be thought Mendelian? A) good gene whoever expression varies according to the sex of one’s transmitting mother B) an excellent gene derived entirely out of maternal inheritance C) a beneficial gene sent through the cytoplasm otherwise cytoplasmic formations D) a good gene sent to people in the maternal range and you can regarding dads to daughters Elizabeth) an excellent gene sent of the a malware so you’re able to egg-creating tissues
45) Genomic imprinting may be as a result of the introduction out of methyl (–CH3) groups so you’re able to C nucleotides so you can silence confirmed gene. A) Methylation out-of C is actually long lasting for the an excellent gene. B) Genetics necessary for early stages of development really should not be published. C) Methylation of this type need certainly to occur more in the males compared to people. E) The brand new imprints is transmitted only to gamete-promoting tissue.
