An XXY chromosome constitution produces ________ development in humans and _________ development in fruit flies.
female; female
female; male
male; female
male; male
male, intersex
Answer: (3)male; female
XXY chromosome in human produce male with Klinefelter syndrome and in fly it produces a female. This difference is due to the fact that selection of sex in flies opperate by X:A ratio.
Give a thumbs up if you like the answer. Thank you
Genetic Experience. An XXY chromosome constitution produces ________ development in humans and _________ development in fruit flies....
Fruit flies are sexually reproducing insects with separate male and female individuals. Like most mammals, including humans, males have an X and a Y chromosome, and females have two X chromosomes. Select the term that describes the organization of the sexual organs in the fruit fly. O hermaphroditic O monoecious O dioecious intersex
A fruit fly is found that has three sex chromosomes (XXY) and three of each autosome. The sex of this fruit fly is _ because ___. A. female; it has a 1:1 ratio of sex chromosomes to autosomes B. male; it has a Y chromosome C. female; it has 2 X chromosomes D. intersex; it has an X:A ratio between 0.5 and 1 E. impossible to determine; sex is influenced by environment in insects
Female fruit flies typically have two X chromosomes; male fruit flies typically have one X and one Y chromosome. They have other chromosomes too that are NOT sex chromosomes. Suppose there is a gene in fruit flies that influences the hairs a fly has on its thorax (the middle section of its body). A recessive allele of this gene causes the hairs to be very thick, while a dominant allele causes the hairs to be very thin. Suppose a heterozygous...
Fruit flies normally have dull red eyes. Some fruit flies have white eyes due to mutation in a gene on the X-chromosome. The white eyed phenotype is X-linked recessive. The sex chromosomes in fruit flies are: females, normally XX; males, normally XY. If a white-eyed female (mutant phenotype) mates with a red-eyed male (normal or wild- type phenotype), what is the likelihood that their female offspring will have red eyes? Parents: white-eyed female X red-eyed male Select one: a. O...

Fruit flies normally have dull red eyes. Some fruit flies have white eyes due to a mutation in a gene on the X-chromosome. The white eyed phenotype is X-linked recessive. The sex chromosomes in fruit flies are: females, normally XX; males, normally XY. If a true breeding red-eyed female (normal or wild-type phenotype) mates with a white- eyed male (mutant phenotype), what is the likelihood that their male offspring will have white eyes? Parents: red-eyed female X white-eyed male Select...
Match each phenotype description to its corresponding sex chromosome genotype in humans. XY with SRY deleted XXX XXY XYY XO with SRY on an autosome phenotypically male but karyotype indicates presence of only X chromosome Answer Bank phenotypically female but karyotype indicates presence of both sex chromosomes phenotypically male with an increase in average stature phenotypically female with some abnormalities and overexpression of X chromosome genes phenotypically male with sterility and hypogonadism
29, In fruit flies, red eyes are dominant over white eyes. The gene for eye color (R) is found on the X chromosome (X^R). Females have 2 X chromosomes and males are XY. Fill in the following (case sensitive!): Genotype of a white eyed female: Possible female gametes; separate gametes with a comma (,): Genotype of a red eyed male: Possible male gametes; separate gametes with a comma (,): In fruit flies, red eyes are dominant over white eyes. The...
An abnormal fruit fly has two sets of autosomes and is XXY. Such a fly would be A. male B. female C. a hermaphrodite D. none of the above
in fruit flies, legs can be straight or bent
QUESTION 9 In fruities, legs can be straight or beet Straight are completely dominant to bentlegs and the gene is located on the X chromosome. There is no corresponding gone on the Y chromosome A female with straight legs with a berting theris crossed with a straight legged male. Define your alles and state the genotype of the female with straight legs. т т т аавы
