What specific observations (evidence) support the conclusions about sex determination in Drosophila and humans?Sort each observation to the appropriate bin. If an observation applies to both Drosophila and humans, sort it to the "Both" bin. If an observation does not apply to eitherDrosophila or humans, sort it to the "Neither" bin.Reset HelpThree sets of autosomesper X chromosomeare required for male fertility.Sex chromosomesare heteromorphic.Maleness is determinedby lack of X chromosomes.Triploid individuals (3n)could be phenotypicallynormal females.XO individuals are male.More than one Y chromosomeis needed for maleness.Diploid XXY individualsare abnormal males.Drosophila onlyHumans onlyBothNeitherSubmitRequest Answer

Answer. Most animals and man plants show sexual dimorphism. In most cases, sex is determined by the…

Three sets of autosomes Sex chromosomes Maleness is determined XO individuals are male. per X chromosome are required for male fertility. are heteromorphic. by lack of X chromosomes. More than one Y chromosome is needed for maleness. Diploid XXY individuals are abnormal males. Drosophila only Humans only Both Neither

DRAW OUT CLEARLY each of these chromosomes labeling as appropriate (demoed in class) The cell has a diploid number of 8 Each pair has a set of linked genes that are located on each end of the chromosome (paternal on left, maternal on right) Pair 1 AB and ab Pair 2 DE and de Pair 3 Fg and fG Pair 4 hI and Hi Show what the chromosomes would look like in G1, G2, TI and TII
Because of non-disjunction in some stocks of Drosophila. melanogaster, about 1 in 65,000 egg cells have two copies of the X chromosome and about 1 in 375 egg cells have no X chromosome. Assuming that meiosis in males is ‘always normal', what is the expected frequency of XXX females and XO males arising from any number of fertilized eggs? Do not be concerned as to whether it is lethal or not.
Abnormal chromosome division during mitosis can result in 47,XXX syndrome. Which statement regarding 47,XXX syndrome is FALSE? -Those with 47,XXX syndrome have 3 copies of chromosome 47 -Thise with 47,XXX may have interllectual disabilities -47,XXX syndrome occurs only in the female sex -47,XXX results in a mosaic phenotype

Having extra sex chromosome can have less serious negative effects than having an extra autosome and some of the individuals can function within a normal range. However, for some of them is very difficult to expect normal life. Make some comparison between 45, X women and 45, Y.
How do the chromosomes in a male human differ from those in a female human? Males have one extra pair of autosomes. Females have one extra pair of autosomes. Males have a Y chromosome, which females lack. Males have two X chromosomes, and females have only one X chromosome.

Chromosome Number The diagram below represents a cell from a jack jumper ant. The cell is about to undergo mitosis and the DNA has been replicated. The jack jumper ant is 2n = 2. is 2n = 4. XX has one pair of homologous chromosomes. has the same number of chromosomes as all other animals. has a haploid number of two.
