The correct answer is explained below:</h2>
Explanation:
- According to the given question,
- For eye color, let the black color be represented by B allele and orange color be represented by b allele. Black is dominant over orange.
- For skin color, let the green skin be represented by G allele and white skin be represented by g allele. Green is dominant over white.
- The phenotype of Sam is black eyes and green skin so his genotype can be BBGG or BbGg. It is also said that one of his parents has phenotype orange eyes and white skin. That parent's genotype must be bbgg.
- Hence, the genotype of Sam must be BbGg.
- Carole has the phenotype of orange eyes and white skin. Her genotype would bbgg.
- The gametes produced by Sam are: BG, Bg, bG, bg.
- The gametes produced by Carole are: bg.
- Mating them we get,
BG Bg bG bg
bg BbGg Bbgg bbGg bbgg
(Black/ Green) (Black/ White) (Orange/Green) (Orange/ White)
- The genotypes and phenotypes (Eye color/ Skin color) obtained are represented above.
- The phenotypes (Eye color/ Skin color) obtained are in the following ratio:
(Black/ Green) : (Black/ White) : (Orange/Green) : (Orange/ White) = 1 : 1 : 1 : 1
Answer: B
Explanation: because birth and immigration is making the group bigger zero deaths and animals leaving
"<span>The second part of the mitotic phase, during which cell division is completed by the physical separation of the cytoplasm components into two daughter cells is called telophase."
Telophase is the last phase of mitosis. The name itself indicates terminal (telo) phase. </span>The chromosomes get to the cell poles and nuclear membranes are formed around each set of chromatids. The actual cell division is called c<span>ytokinesis and it starts at the end of the telophase.</span>
