- the theory of the inheritance of acquired characteristics and noted that this theory is no longer accepted. Is the central dogma consistent with the theory of the inheritance of acquired characteristics? Why or why not?arrow_forwardIdentical twins have identical but they do not have identical adult phenotypes. ---- This is caused by responses to the different environments they encounter. genotypes; mitochondrial DNA mitochondrial DNA; genotypic autosomal DNA; genotypic epigenomes; genotypic genotypes; epigeneticarrow_forwardFill in the Blanks When two alleles are equally expressed, this is called (blank) .arrow_forward
- an example of a condition which is inherited via homozygous genes and one which is heterozygous. Do not use things like hair color or the color of Mendel’s pea plants here- discuss genetic disordersarrow_forwardhow genotype and phenotype are relatedarrow_forwardTraits are inherited germ line wise (vertical inheritance) and somatic (epigenetics) inheritance, what exactly is the difference in the traits manifestation between the two indicated inheritances?arrow_forward
- Suppose a maternal effect gene exists as a functional dominantallele and a nonfunctional recessive allele. A mother who is phenotypically abnormal produces all normal offspring. Explain thegenotype of the motherarrow_forwardMendelian Genetics and Non-Mendelian Genetics: Huntington’s disease, a neurodegenerative genetic disorder that typically becomes noticeable in middle age, is due to an autosomal dominant allele. Sickle cell anemia, on the other hand, is a genetic blood disorder due to a recessive allele. Jillian is a carrier of the allele for sickle cell anemia but has no sign of any neurodegenerative disorder in her family. She married Jacobwhose father died of Huntington’s disease. His mother, however, is not inflicted with that condition. Neither of his parents exhibit sickle cell anemia. 1. Give the genotypes of Jillian and Jacob. Assuming that they will have 4 children, what is the probability that: 2. all their children will be normal? 3. they will have a son with Huntington’s disease? 4. they will have a daughter inflicted with both conditionsarrow_forwardWhen both the alleles of a gene express themselves in heterozygous condition, the phenomenon is called---------arrow_forward
