Answer:
The circulatory system consists of the heart, the arteries, veins, and capillaries.
Explanation:
Copies of the original DNA strand
Answer:c. each of two alleles for a given trait segregate into different gametes.
a. it possible to determine the genotype of an individual of unknown genotype who exhibits the dominant version of a trait
Explanation:
The law of segregation of genes is examplifed with MEIOSIS 1 ,where sister chromatides ( alleles of a gene on the same locus) separated and behave independently of each other by positoning themselves on different spindles at Metaphase 1 for crossing over and independent assortment.
They migrated independently at Anaphase 1 to reach the equators which afrer telephase 1 and Telophase 2 i are located in different gametes.
Therefore the alleles of the genes behaved independently of each other,carting different genetic components to gametes.
Chemical (mutagens)
usually either mimic the structure of nucleotides and are inserted in DNA or either cause
chemical changes (such as alkylation) in nucleotides hence causing mismatching during replication.
Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an
increased likelihood of mutations during the repair of the DNA by cell
mechanisms.
<span>XX is the genotype. think of it this way;;
if you got a y, you're a guy.
it rhymes.
males are XY.</span>
