please answer all, I'll give thumbs up
Transcribed Image Text:1. The somatic cells of cabbage contain 14 chromosomes. How many are present in each cell
at the stage of mitosis or meiosis indicated? (Assume cytokenesis to occur at mid-
telophase).
(a) chromatids at Anaphase-l
(b) chromatids at Anaphase
(c) chromosomes at Metaphase-l
(d) chromosomes at the close of Telophase-I
(e) chromosomes at Telophase II.
Transcribed Image Text:3. The letters below represent genes found on different chromosome pairs. Letters that are
similar represent one gene found in a pair of homologous chromosomes. Another letter
represents another gene found in another pair of chromosomes. Draw how these different
pairs of chromosomes behave during meiosis. Use the back of these sheet for your drawings.
(a) Cc (b) BbCC (c)DdEe (d) AAbbCc (e) AaBbCcDd
How many different* gamete genotypes will be produced by individuals of the following
genotypes if all genes shown are on different chromosome pairs. (Indicate the genotypes of
each gamete of (a), (b) and (c)) *By different, meaning different chromosome combinations. For
example: Ef is the same as fE → these are the same chromosome combinations, even if
arrangement as to which is written first, are different.
