Females have two X chromosomes while males have one X and one Y chromosome
Answer:
Genotype: Bb (heterozygous)
Phenotype: brown fur
Explanation:
Since allele B is dominant to allele b, as long as genotype has allele B in it, its effect of phenotype will be expressed instead, regardless of whether allele b is present.
As mouse genotype is stated as Bb, on the chromosome from its parents, allele B comes from one parent while allele b is inherited from the other parent.
Phenotype is the expressed trait. In this case, as genotype has allele B, the phenotype will be brown fur as its effect is expressed.
Answer:
That hemoglobin is the substance that transports oxygen..
Viral replication involves six steps: attachment, penetration, uncoating, replication, assembly, and release. During attachment and penetration, the virus attaches itself to a host cell and injects its genetic material into it.
toxic enzymes that damage the host cell that are coded for in the viral genome
secretion of chemicals from the virus to the membrane of the host cell
replication of the viral genetic material within the host
lysis of the host to release new viruses
integrating into the host cell chromosomes
