Meiosis: A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

<span>Mitosis:<span> A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.</span></span>

<span>Heredity: T<span>he passing on of physical or mental characteristics genetically from one generation to another.</span></span>

Tortoise shell cats, like the one shown above, are always femaleWhat scientific phenomenon explains the color pattern of
8_murik_8 [283]

Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.

The scientific phenomenon that explains the color pattern is X-linked incomplete dominance.

  • As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked.
  • This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.

Sonja [21]

1. Whorls

2. Organs

3. Symmetry

<u>Explanation:</u>

Some important traits that influence the reproductive success of a flower include: the presence or absence of whorls, the fusion of organs to one another, and the overall symmetry of flowers.

In the process of reproduction in plants, the male and female gametes are produced and transfer of the male gametes to the female ovules occurs. This process is called as pollination. After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit

Floral  zygomorphy confers a reproductive advantage to rare plants" as a result of the  enhanced pollination efficiency.

posledela

The correct answer is:

D. It divides one diploid cell into four haploid cells.

Explanation:

Meiosis is a specific type of cell division that reduces the chromosome number by half, forming four haploid cells, each genetically different from the parent cell that yielded growth to them. Meiosis is a method where a single cell divides double to produce four cells comprising half the innovative amount of genetic information.
