Answer:
a) BB
b) bb
c) Bb
Explanation:
Co-dominance is a type of non-mendelian genetic inheritance in which two alleles of a gene are neither dominant nor recessive over one another, hence, they form an hybrid offspring that simultaneously exhibits the traits encoded by both alleles. This is the case of the scale color gene in a certain fish. The allele for blue scales (B) and allele for red scales are codominant. Hence, they produce an hybrid with a patchwork of both blue and red colours.
Therefore, a fish with blue scale color will possess an homozygous genotype of the blue allele: BB while a fish with a red scale color will possess an homozygous genotype of the red allele: bb. Since the patchwork fish is an hybrid or heterozygous, it will contain a combination of the blue and red alleles i.e. Bb.
Because both alleles (red and blue) are codominant, both traits encoded by both alleles will be expressed at the same time in the hybrid organism (patchwork fish).
The atmosphere interacts with the hydrosphere through the water cycle.
Water cycle:
• Evaporation of water (from the earth’s surface-due to the heat from the sun,
• Cold Trap- a point reached by the water vapor when it gets higher into the atmosphere (this point is substantially colder than the air below it)
• Condensation of water- the water vapor turns into water droplets as it cools down, they connect to form clouds
• Precipitation of the watee- water falls in the form of which is usually rain.
The water flows into rivers, streams, and fall directly into the ocean, where the cycle can restart.
Answer:
Deoxyribose sugar and phosphate groups
Explanation:
The Deoxyribose and phosphate groups are held together by hydrogen bonds. The Deoxyribose is also connected to the nucleic acids, making a complete nucleotide. Deoxyribose is only used in DNA, because DNA means Deoxyribonucleic Acid. RNA is made with a sugar called Ribose.
The ability to get moree human attention.
Answer:
The function of Mitosis is to produce daughter cells that <u>are genetically identical to the parent cells</u>. have the same number of chromosomes as the parent cell but not the same genetic make-up are genetically identical to the parent cell have a random assortment of maternal and paternal chromosomes
(The answer is underlined above)
Explanation:
Mitosis is a nuclear division. This division results in the generation of two daughter cells that are genetically identical to the parent cells and each daughter cell contains the same number of chromosomes and all cell content inherited from the parent cell. Mitosis is involved in cell development of new cells and old one, growth of both new cells and old ones, and asexual reproduction.
The chromosomes which are the DNA molecule that makes up the fundamental genome of the cell are copied before mitosis. This made sense to explain how important it is for chromosomes of the cell to be copied first before mitosis so as to enable the separation of the chromosome copies to give each cell a full set of identity similar to the one copied from.
