Question
Answer
Chromosome Mutation can be because of   numerical chromosomal abnormalities, which affects the number of chromosome in the cell (e.g. monosomy, trisomy, polysomy, etc) structural, which affects the structure of individual chromosomes such as deletions, duplications, inversions, translocations.  
🗑
Gene Mutation   Affects individual genes In a dominant mutation, the phenotype is expressed even when there is only one mutant allele. In a recessive mutation, both alleles must be present to have any effect on the phenotype.  
🗑
Genetic Polymorphism   The co-existence of many forms of DNA sequences (wild type sequence of a gene) at a locus in a population.  
🗑
Population Genetics   It is the quantitative study of the distribution of genetic variation in populations and of how the frequencies of genes and genotypes are maintained or change.  
🗑
Population Genetics is applicable if   the population is large and matings are random Individuals with all genotypes are equally capable of reproducing and passing on their genes  
🗑
triplet expansion   is the mutation that occurs because of amplification of triplet nucleotide repeat sequence during sex cell reproduction  
🗑
Population Genetics is not applicable if there is   cosanguinity&Inbreeding or Mutation and selection  
🗑
The shorter the distance between two genes on the same chromosome,   the smaller the probability of a crossover.  
🗑
homeobox genes   HOX genes encode for a group of 60-amino-acid- proteins called transcription factors that binds to DNA. In doing so, they control cell differentiation (through gene regulation) and therefore formation of body structures during embryonic development.  
🗑
Morphogens   chemicals that induce,control fate of the cell during development(or morphogenesis), coordinate cellular growth and patterns  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
