how does the random alignment of homologous chromosomes contribute to genetic variation in a population
SCORPION-xisa [38]

The assortment of homologous chromosomes during meiosis is random and generates genetic variation, the raw material for evolution.

During metaphase I of meiosis, homologous chromosomes are lined up at the equator plate of the cell in order to be separated (assorted) in anaphase I.

The separation of homologous chromosomes during meiosis I is random. Daughter cells receive unique gene combinations from an original parent cell.

Subsequently, haploid cells got from two successive meiotic divisions fuse during fecundation to form a diploid (2n) zygote.

During prophase I, non-sister chromatids interchange genetic material by a process known as recombination. This genetic process also increases genetic variation in daughter cells.

In conclusion, the assortment of homologous chromosomes during meiosis is random and generates genetic variation.

Mitosis and meiosis 1 comparison of all phases
Aleksandr-060686 [28]

Answer and Explanation:

Mitosis is the type of division that occurs in the general body cells resulting in growth while meiosis is the process that occurs during the formation of sex cells. Mitosis results in two daughter that are identical to one another and to the parent cell. In meisosis there is crossing over during prophase I.

For each region of the lac operon on the F' plasmid, I+ P+ Oc Z− Y+ , determine whether the region is wild type (that is, it pro
UNO [17]

Answer:

A,B and E

Explanation:

  • I+: I refers to the lac repressor, the + indicates that the repressor is functional
  • P+:  P refers to the promoter region and the + indicates that the promoter is functional
  • Oc:  O refers to the operator region, but the Oc indicates that the operator is constitutive ie. that it is always on/ can't be turned off.
  • Z-: Z refers to the LacZ gene which produces β-galactosidase. Z- indicates that this gene is non-functional
  • Y+:  Y refers to the LacY gene which produces the permease protein. Y+ indicates that this gene is functional

So based on the breakdown above:

  • A is true because P+.
  • B is true because I+.
  • C is not true because the lac operon is an inducible system. The operator needs to be able to be repressed. In this case the operator is constitutive (always on)  which is not the correct form.
  • D is not true because Z-, no β-galactosidase is produced.
  • E is true because Y+.

Only A, B and E apply.
