Answer:
X-Chromosomes.
Explanation:
Characters determined by a gene located on only the X-chromosome are said to be sex-linked. Such traits show a different pattern of inheritance in males and females. For example, a recessive allele on the X-chromosome
• would be masked in a female if the corresponding allele on the other X-chromosome is dominant;
• would always be expressed in a male because the Y-chromosome does not have a corresponding(active) allele.
Thus, the female may posses a homozygous or heterozygous allelic pair for a sex-linked character, but a male will only have one allele for it.
Science has no opinions, yet though is usually biased.
Answer:
The idea of spontaneous generation was disproved by Francesco Redi.
Explanation:
- Spontaneous generation is a theory that states that living organism can generate from an inanimate object.
- In, 1668, Francesco Redi demonstrate an experiment explaining the theory of spontaneous generation by using meat.He noticed that flies laid eggs on meat which was kept open and maggots developed.
- He took three pieces of meat to do the experiment.
- The first piece of meat was kept open and as usual maggot development takes place.
- With the 2nd piece of meat,he covered it with a piece of cheesecloth and noticed that,flies lay eggs on the cheesecloth but when he removed the cloth,maggot did't form.
- Next, he took a piece of paper and cover the meat piece, and he noticed that flies did't lay any eggs and thus no maggots formed.
