The numbers of chromosomes in the somatic cells of several oat varieties (Avena species) are as follows: sand oats (Avena strigosa): 14 slender wild oats (Avena barata): 28 cultivated oats (Avena sativa): 42 Based on this information, you can infer that the basic chromosome number in Avena is 1. _______ and that sand oats (Avena strigosa) are 2.______ and will produce gametes that have 3._______chromosomes each. 1. 14 , or 42, or 28 , or 7 2. monoploid , or diploid , or tetraploid 3. 7 , or 28 , or 14 , or 21 Select the correct option for the blank.
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
The numbers of chromosomes in the somatic cells of several oat varieties (Avena species) are as follows:
sand oats (Avena strigosa): 14
slender wild oats (Avena barata): 28
cultivated oats (Avena sativa): 42
Based on this information, you can infer that the basic chromosome number in Avena is 1. _______ and that sand oats (Avena strigosa) are 2.______ and will produce gametes that have 3._______chromosomes each.
1. 14 , or 42, or 28 , or 7
2. monoploid , or diploid , or tetraploid
3. 7 , or 28 , or 14 , or 21
