Why are aneuploidies in autosomal chromosomes likely to cause more severe
Step by step
Solved in 2 steps
- what is the significance of chromosomal aberration? what are the different types of chromosomal abberations based on the structure and number of chromosomes? give examples for each. what environmental factors may increase in the incidence of chromosomal aberrations?Why is the incidence of survivable genetic disorders involving deletions of parts of chromosomes so rare? Why is the incidence of trisomy of larger chromosomes rarer than the incidence of trisomy of smaller chromosomes? What is the relationship between the severity of symptoms and the size of chromosome involved in the trisomy?What is the number of sex chromosomes in male honey bees? We know that the chromosome set of males in honey bees is 1n and the chromosome set of female honeys is 2n, and based on this, the number of autosomal chromosomes in male honeybees is 16 chromosomes, and the number of autosomal chromosomes in female honey is 32 chromosomes, but if The male was haploid (1n) Will this make the number of autosomes equal to the number of sex chromosomes? Please clarify the answer
- Explain why autosomal aneuploidy is generally more deleterious than aneuploidy for sex chromosomes.Familial Down syndrome is similar to primary Down syndrome in that it is caused by trisomy 21. However, in familial Down syndrome, all or part of the third copy of chromosome 21 has translocated onto another autosome, typically chromosome 14. In cases of familial Down syndrome, one of the parents of the affected child is often a carrier of a translocated chromosome. The translocation carrier parent does not have Down syndrome because he or she has a total of two copies of chromosome 21. Suppose that a woman is a translocation carrier of chromosome 21 on chromosome 14. She conceives six zygotes with a man who carries no aneuploidies. Match the description of the chromosomes inherited by each zygote with the viability and phenotype of the zygote. ✓ Two normal copies of 14, two normal copies of 21 two normal copies of 21, one normal copy of 14 ✓one normal copy of 14, one 21 to 14 translocation, one normal copy of 21 ✓two normal copies of 14, one normal copy of 21, on 21 to 14…Two phenotypically unaffected parents produce two children withfamilial Down syndrome. With regard to chromosomes 14 and 21,what are the chromosomal compositions of the parents?
- Why do individuals with an excessive number of sex chromosomes often show minimum phenotypes?In general, why do changes in chromosome structure or numbertend to affect an individual’s phenotype?

Describe two types of genetic disorders that can result from nondisjunction.
- A normal mother has translocations on chromosomes 14:21. With respect to chromosomes 14:21, how many combinations of chromosomes are possible? How many gametes are viable? If the woman has children with an normal father, what is the probability that there is a daughter with Down Syndrome or a son with an unaffected phenotype?What kind of chromosomal mutations is/are produced by unequal crossing over?For the following chromosome complements, what is the phenotypic sex of a person who has Q. XX with a copy of the SRY gene on an autosomal chromosome?
