Males have two different chromosome that determine their sex: X and Y
Females have two of the same chromosome which determines their sex: X and X
Chromosomes carry genetic information, and they are called X and Y because that's just just what they look like coincidentally. Look it up! It's pretty interesting.
Answer:
Yes.
Explanation:
Yes, she can only distinguish about two thirds of the smells because of the mild anosmia while on the other hand, if she has full anosmia she loss the ability of smell. Mild anosmia is the disease which takes half or some part of the ability but in the case of complete or full anosmia, the patient has lost the ability to smell completely so that's why mild anosmia enable her to distinguish about two thirds of the smells as compared to full loss of smell ability.
Answer:
One of the parents is heterozygous for red (Rr) and the other is homozygous for white (rr)
Explanation:
The ratio of red flowers to white flowers is roughly 50:50 in this cross (51:47)
Assuming red is the dominant trait, and white is the recessive trait, the parents would be Rr (heterozygous red) x rr (homozygous white).
The resulting punnet square (attached) shows that the genotypes are 50% Rr and 50% rr, which would be 50% red and 50% white. Therefore the parents are RR and Rr.
If red is the recessive phenotype, then the opposite would be true, the white parent would be heterozygous and the red parent would be homozygous.
<span>The myelin sheath allows nerve impulses to propagate very quickly along a nerve's axon to transport the signal between nerve cells. The myelin coating allows the chain reaction of impulses to jump certain distances instead of waiting for the chemical changes to happen at all points on the axon.</span>
They uncover evidence of crimes, mostly things involving dna like finger prints or blood.
