A cell from a tissue culture has 38 chromoses after mitosis and cytokinesis one daughter cell has 37 what might occurred to cause the abnormal chromosome number
Answer:
occurred an aneuploidy (monosomy)
Explanation:
Aneuploidy can be defined as a chromosomal aberration in which the chromosome number is abnormal. In an aneuploidy, the number of total chromosomes in daughter cells is not an exact multiple of a haploid set, by either gaining or losing chromosomes during mitosis. Aneuploidies are common in cancer cells and in different types of chromosome disorders. Moreover, monosomy is a type of aneuploidy in which daughter cells have a single chromosome copy instead of the two copies found in diploid cells. For example, Turner syndrome is a monosomy caused by the loss of the X chromosome.

Y: Parasitism
Z: Mutualism
Explanation:
X: commensalism
Rationale: in this type of relationship, only one organism benefits while the other does not benefit and is also not harmed in anyway. Whale doesn't benefits and it's not harmed by the Barnacles that benefits from the association.
Y: Parasitism
Rationale: in parasitism, one organism suffers while the other benefits in the relationship.
The fleas on warm-blooded animals is the organism that benefits solely from the association while the animals suffer.
Z: Mutualism
Rationale: in this relationship, both organisms benefit from the association and do not harm each other.

A woman with blood type a (whose parents both had AB blood) mates with a man with blood type B (his mother was AB and the father was O blood). Show the cross and the genotype and phenotype ratios of the potential offspring.
Answer:
1 AB:1 A
Explanation:
Ia Ia
Ib IaIb IaIb
i Iai Iai
i represents type O blood which is always recessive
the capital I represents co-dominant traits (a or b)
Iai is type A because O is recessive and will be masked by Ia
IaIb is type AB because both capital I traits will be codominant
This cross ultimately gives a 1:1 ratio of type A to type AB
