Part A: Drag the labels to the correct locations on these images of human chromosomes
Revelant knowledge
Each cell in the human body has 23 pairs of chromosomes, for a total of 46. Twenty-two of these pairings, referred to as autosomes, are identical in males and females. Males and females have different sex chromosomes, the 23rd pair. Males have one X and one Y chromosome, while females have two copies of the X chromosome.
Answer:
a – homologous hromomes: This is a chromosome pair that are inherited from both parents. One from the male and one from the woman. These chromosomes have the same gene position, but they may have different alleles.
b – centromere: The region of the chromosome that the sister chromatids attach to and where spindle does attach to centromere during mitosis.
c – ister chromatids: Half of the chromosomes that have been duplicated.
d – autosomes: These chromosomes do not account for sex determination.
e – sex chromosomes: Out of 23 pairs of chromosomes found in humans, one is the sex-chromosomes that determine sex.
f – karyotype: Is a picture showing the chromosomes in a person. It shows the number, size and shape of the chromosomes.
