Somatic mosaicism is when an individual contains two distinct cell populations as a result of a postzygotic mutation, with phenotypic consequence partially influenced by the extent of chromosomal rearrangement. Question Chromosomal rearrangement is implicated in what somatic change? correct answers Malignancy Rearrangement of chromosomes is a somatic change implicated in malignancy. After 24 hours of fasting what is the source of energy (for gluconeogensis)? correct answers Amino Acid...

Requirements for Hardy-Weinberg equilibrium - ️️1. No mutations 2. Large population so random chance does not cause allele frequency changes 3. No migration in or out of the population 4. Random mating happens 5. No phenotypic advantage is present Analogous structures - ️️Parts that have the same function, but developed from different lineages Genetic bottleneck - ️️Losing genetic or phenotypic diversity due to genetic drift Gene flow - ️️Movement of new alleles from one ...
