Answer:
a difference between mitosis and meiosis is that, during mitosis there is only one cell division, so the cell goes through the steps of prophase, metaphase, anaphase, and telophase once.Specialized cells are unable to survive independently of each other and have to develop complex systems of communication such as the circulatory and nervous systems in order to survive. If one system dies, the entire organism is likely to follow.
Explanation:
Answer:
(i) An allele is a variant of a gene, can either be short or tall.
Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.
(ii) David's eyes are Brown
(iii) Sarah's eyes are blue
(iv) David - B, b
Sarah - b, b
(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.
(vi) The chance for blue eyes is 50% (or 1:1 ratio)
