Genetic recombination occurs due to.

a. the production of genetically identical daughter cells after mitosis.
b. crossing over between homologous chromosomes.
c. proper alignment of paternal chromosomes and maternal chromosomes on the proper side of the metaphase plate.
d. a differing number of homologous chromosomes in each of the daughter cells after meiosis I.

Genetic recombination occurs due to crossing over between homologous chromosomes.

Explanation:

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

complete the square on the right side of the equation;

-5(x + 0)^2 + 15

answer: d. y = -x^2 + 15
