This law is called Mendel's second law, or the Law of Independent Assortment.
The law is derived from observations of dihybrid crosses. A classic example involves seed shape and color in garden peas. The shape may be round (caused by a dominant allele, denoted by R) or wrinkled (recessive, r). The wrinkling is caused by a mutation preventing the formation of branches in starch molecules. The color of the seeds may be yellow (dominant, Y) or green (recessive, y). The green color results from a variant sequence in a gene; the seeds fail to develop normally.
Parentals are RRYY and rryy.
The F1 plants are RrYy.
The F2 plants show independent segregation of the alleles for the two characteristics, shape and color. A Punnett grid predicts a 9:3:3:1 ratio for the phenotypes round yellow, round green, wrinkled yellow, and wrinkled green.
Answer:
during prophase, the nuclear membrane around the nucleus begins to disintegrate.
Answer:
One of the RNA molecules has experienced gene duplication as the result of translocation.
Explanation:
Translocation and duplication are some of the structural abnormalities in the chromosomes that may even cause certain genetic disorders. Duplication is the presence of a genetic segment for more than one time in the chromosome. The repeated genetic segments are mostly present in the tandem pattern. When a chromosome fragment breaks off and attaches to a non-homologous chromosome, it is called translocation. It leads to the deletion of a genetic segment in one chromosome and duplication in the other.
According to the given information, a genetic segment bearing two genes is detached from one RNA and gets attached to the other RNA molecule of the HIV genome. Therefore, the RNA molecule has undergone translocation and has lost a genetic segment while the other has gained a genetic segment (duplication) due to translocation.
Answer:
Heat is produced.
Explanation:
Law of conversation of energy and mass these can't be created or destroyed, but can be converted to another form. The fuel/chemical energy is being converted into heat.
To breathe, they use the <span>the carbon dioxide. Carbon dioxide is the main element which help the organisms to breathe.</span>
