Determine the mode of inheritance:
Homozygous recessive die from fatal disorder, when a specific enzyme activity is absent. Heterozygous exhibit wild type phenotype but have intermediate level of gene expression resulting in 1/2 of the wild type enzyme activity when compared to Homozygous normal non-carriers. Based on the levels of gene expression ALONE, the mode of inheritance is?‐---------------

- Which of the following defines polygenic inheritance? An inheritance pattern in which one allele is not fully dominant over another, so the heterozygous phenotype is an intermediate blend of the two homozygous phenotypes An inheritance pattern in which the full and separate phenotypic effects of two alleles are apparent in heterozygous individuals An inheritance pattern in which a single gene affects multiple traits A pattern of inheritance in which multiple genes affect one traitarrow_forwardYou possess two alleles for each of your genes. (One from the paternal side and one from the maternal side in each homologous pair of chromosomes.) In simple inheritance, having at least one dominant allele (form of the gene) means you will display the dominant phenotype, and the only way to display the recessive phenotype is to have two recessive alleles. For example, individuals with the genotypes RR and Rr can roll their tongue (into a U shape). If you cannot roll your tongue, then you know with certaintly you have the genotype rr. If you can roll your, you would write your genotype as R- (R followed by a dash since you might not know if you are RR or Rr, but either way, you display the dominant phenotype because the first letter is capital.)

- Mendel's concept of dominance states that in a genotype where two different alleles of a locus are present, only the trait encoded by the dominant allele is observed. Give a molecular explanation for dominance, i.e. explain intracellular molecular events that can result in what we observe as dominance on a phenotypic level. Use the gene that encodes seed shape in peas as an example, where roun(R) is dominant over wrinkled(r), to explain how RR and Rr plants can have the same phenotype.arrow_forwardExplain the term maternal inheritance? Which characters show this type of inheritance?arrow_forwardIn humans, cystic fibrosis and albinism are both inherited as independently assorting autosomal recessive traits. Use f to represent the recessive allele for cystic fibrosis and F for the allele for the unaffected condition. Use A to represent the dominant allele for normal melanin and a for the recessive allele for albinism. A man is albino and heterozygous for cystic fibrosis. His wife has the unaffected phenotype for both traits, although her father had cystic fibrosis and her mother is albino. 4a.

- Mendel's second postulate states: When two different unit factors responsible for a characteristic are found in the same organism, one will dominate and determine the characteristic type.
