1. Explain how the traits of an organism are related to the genes in DNA.

Genes in DNA or responsible for the traits an organism has. This is caused by Dominant and Recessive Traits. Remember that Genotypes are the genetic letters such as RR, Rr, and rr. Phenotype is physical traits.

Dominant Traits are more likely or always show in the offspring. The Dominant Genotype uses Capital letters such as RR.

Recessive Traits are less likely to show up. Their Genotype use lower case such as rr. Now genotypes of Rr have one dominant trait and one recessive trait. If the dominant trait was black fur and the recessive white fur, the offspring will be black fur because dominant traits overpower the other.

To understand how to know if an organism will have Dominant or Recessive Genes, you have to use something called a Punnet Square. Lets imagine 2 parents both have the genotype Rr. R is Black fur and r is white fur. As you can see from the chart, 3 of 4 boxes have Rr and 1 rr. Since there is a Dominant Trait with a Recessive, they will show a Dominant Phenotype, or Black fur. This has 3/4 chance and a 1/4 chance for white fur in the offspring.

Which of the following options correctly describes the behavior of a tetrad during anaphase 1 of meiosis?
Svet_ta [14]

The answer is; C

Homologous chromosomes have the same genes on the same loci. However, they may have different forms of the same gene called alleles. These sister chromosomes, of a homologous pair, separate during anaphase I of meiosis. The two daughter cells formed will, therefore, have half the genetic material as the parent cell. This is because they will only have one set of the genes (as in diploid organisms) and are called gametes.

What is meiosis and mitosis simple definition?
Temka [501]

Mitosis is a type of cell division for somatic cells and for the asexual reproduction of unicellular eukaryotic cells.

Meiosis is the type of cell division for the production of gametes in sexual reproduction . Meiosis is the process through which egg and sperm cells are formed. Mitosis is a necessary step for life.

A cell copies all of its components, including its chromosomes, and separates to generate two identical daughter cells during mitosis.

Meiosis is a form of cell division that occurs in sexually reproducing organisms and results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).

Mitosis is the division of a single cell into two identical daughter cells (cell division).

Mitosis is a kind of cell division that occurs in somatic cells as well as in unicellular eukaryotic cells during asexual reproduction. Meiosis is a sort of cell division that occurs during sexual reproduction to produce gametes.
