Answer:

Two heterozygous parents have a <u>50%</u> chance of contributing one of their alleles to each offspring.

Explanation:

Individuals who are heterozygous for a specific trait have two different alleles in the gene that determines that trait. This characteristic makes their chances of contributing each of their alleles to the offspring 50%.

The alleles of a gene are distributed in the gametes by the process of meiosis, which results in daughter cells with half the genetic charge, so each gamete can only have one copy of the allelic pair of a gene.  

On the other hand, if an individual has two equal alleles for a characteristic in a gene, he has a 100% chance of passing that allele on to his descendants.

In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis.
zhenek [66]

Answer:

Mitosis involves in cell division.

Explanation:

Mitosis may be defined as a process of cell division which results in the formation of two daughter cells each from a parent cell and each cell having having the same number of chromosomes and chromosomes of the same type as that of the parent nucleus.

The main difference between meiosis and mitosis of a nucleus cell is that it involves only one cell division. And so the cell goes by the steps of prophase, then metaphase, then anaphase and finally telophase. The specialized cells could not survive independently to each other, so they have to develop some complex system of communications like the circulatory system and the nervous system. In this way they can survive. If one of the system dies, entire organisms is more likely to follow.
