Answer:
Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid
Explanation:
The uterus receives eggs and supports the growing embryos development until birth. Rats have a uterus consisting of the right and left cornua (horns) referred to as a bicornuate uterus. This structure enables the rat to have multiple offspring. The horns of the uterus come together to form the vagina.
Answer: The phenotypic variation was more in play during the tests because of the presence of environmental factor (monochromatic light). The genotypic variation was a result which is evident in the viable and fertile hybrids
Explanation: Phenotypes are traits of living things which are visible to us. Examples of such traits are behaviours, colour, shape, size, e.t.c. Genotypes is the genetic blueprint of a living thing. It is the genetic code that forms the physical traits in an organism (phenotype). For example, the code that tells a lady to have red hair is the genotype while the resulting red hair in the lady is the phenotype.
Phenotypic variations simply put are different physical variables in phenotypes that exists in a given population. For example, we have people with different body weights, heights, eyecolour, hair and shape of head. Genotypic variation is the difference in genotypes between different species or individuals of the same species.
There are two known causes of phenotypic variations and they are genes or environmental factor. In the given data, the monochromatic (made of one colour) light induced phenotypic variations in the male species and led to indiscriminate mating which resulted in viable and fertile hybrids (genotypic variation).
Meiosis and mitosis are both preceded by one round of DNA replication; however, meiosis includes two nuclear divisions. The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell.
so the similarities are:
-ways for cells to divide
-same number of chromosome as the original cell
-both have the basic 5 phases
-both processes go through chromosome replication
-Meiosis II is similar to Mitosis
I hope this is helpful :)))
have a nice day
