A population was observed to increase from 5000 to 6000 individuals in one year, What is the rate of increase? - Rate of increase = 6000/5000 Advantages of reproducing later in life? - More resources available for Individuals An allele that is advantageous early in life but will be deleterious later in life will be SELECTED because of greater contribution of the early classes. TRUE OR FALSE? - TRUE Another Simple Case assumption? - The rate at which a population increases is a simple multip...

Chapter 8: Complex Inheritance of Common Multifactorial Disorders 1. Which of the following is characteristic of multifactorial inheritance? A) Disorders caused by a single gene mutation B) Disorders influenced by both genetic and environmental factors C) Disorders only transmitted through mitochondrial DNA D) Traits passed solely through dominant alleles Answer: B Rationale: Multifactorial disorders arise from the interaction of multiple genes and environmental factors, such as lifestyl...

What is the correct order of events in the cell cycle? - correct answer G1,S,G2,mitosis, cytokinesis How does crossing over increase genetic diversity? - correct answer It increases the number of distinct combinations of genes that may be present in a gamete. A trait that shows continuous variation is typically influenced by? - correct answer both genes and environmental factors If DNA sequence of aj gene reads, in part, TAACAGGTCA, what is the sequence of the complementary strand...

name three factors affecting independence (and F2 ratios) Ans: -pleiotropy -epistasis -linkage What is pleiotropy? Ans: When 1 gene (locus) has more than 1 effect on an individuals phenotype (eg. W allele in cats causes both white fur and deafness) What is epistasis? Ans: a gene at one locus alters the phenotypic expression of a gene at a second locus (eg. W allele masks all other colour or pattern genes in cat coat when present) P Ans: frequency of the homo dominant (AA) genotype ...
