| 21. | The first 22 pairs of chromosomes ( called autosomes ) are numbered from 1 to 22, from largest to smallest.
|
| 22. | Humans have 23 pairs of chromosomes, often split into the 22 pairs of autosomes and one pair of sex chromosomes.
|
| 23. | Their experiments have shown how the ratio of sex chromosomes to autosomes can initiate a novel regulatory pathway involving RNA processing.
|
| 24. | Fridolfsson's team has found evidence that the sex chromosomes of birds are indeed descended from an ancestral pair of autosomes.
|
| 25. | Spinal muscular atrophy is inherited in an autosomal recessive pattern, which means that the defective gene is located on an autosome.
|
| 26. | The possible interactions of Y chromosome are X-Y, Y-autosome and Y-cytoplasm ( Paras 2006 ).
|
| 27. | The short and long arms of the pair of submetacentric autosomes correspond respectively to the 27th and 1st chromosomes in cattle and goats.
|
| 28. | As well as autosomes, human neocentromeres have also been observed in sex chromosomes, and correlate with some sex-linked diseases.
|
| 29. | The results were that balanced gene expression between X and autosomes gene expression was decreased by 10 15 % no matter the method of inhibition.
|
| 30. | The animal has a karyotype of 46 chromosomes, with a total of 50 major arms on the autosomes ( non-sex chromosomes ).
