Which statement explains the difference in chromosomes in fruit fly (2n=4)?

Biology

Aloiza [94]3 years ago

Answer:

O Fruit fly gametes have 2 chromosomes while parent cells have 4 chromosomes.

Explanation:

The fruit fly is a diploid (2n) species with a chromosome number equal to 4, which means that somatic cells have two sets of homologous chromosomes, each set composed of two chromosomes (2n = 4). Moreover, fly gametes are haploid (n) cells, containing each a complete set of two non-homologous chromosomes (i.e., half the amount of DNA compared to parent cells). During meiosis, a single cell divides twice following one complete round of DNA replication, producing thus four gametes with a haploid number of chromosomes.

Answer:

d. Monosomy X is the only viable monosomy known to occur in humans.

Explanation:

Human have 22 pair of homologous chromosomoses and an extra pair of sex chromosomes. While in males  the sex  chromosomes  are X and  Y , females have two chromosomes X . Anyway, in normal conditions the total number of chromosomomes that humans have in their cells is 46 (23 pair of chromosomes).  

Aneuploidy is a biological condition where an individual have an abnormal number of chromosomes in their cells.  In humans for examples, this would be a human having more or less than 46 chromosomes.

The Turner syndrome also called  monosomy X is an aneuploidy  where  one of the X chromosomes is missing in a female.  Although under constant supervision, people with Turner syndrome have viable healthy lives. However this is the only monosomy that occur in humans that is compatible with life.
