What is the difference between de jure segregation and de facto segregation?
De jure segregation is understood to be unconstitutional in the United States, requiring a proactive remedy. When segregation is deemed de facto, the state bears no burden of redress.
Which is the best definition of de facto segregation?
During racial integration efforts in schools during the 1960’s, “de facto segregation” was a term used to describe a situation in which legislation did not overtly segregate students by race, but nevertheless school segregation continued.
How do you use the law of segregation?
When an organism makes gametes, each gamete receives just one gene copy, which is selected randomly. This is known as the law of segregation. A Punnett square can be used to predict genotypes (allele combinations) and phenotypes (observable traits) of offspring from genetic crosses.
What is the Law of Independent Assortment in genetics?
The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop. During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.
What allele means?
An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.
Who is the pioneer of modern genetics answer?
Gregor Mendel was an Austrian scientist, teacher, and Augustinian prelate who lived in the 1800s. He experimented on garden pea hybrids while living at a monastery and is known as the father of modern genetics.
What are different forms of genes called?
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
