Which of the following statement is correct regarding law of segregation?
Answer: law of segregation states that the two factors for a trait, present together in a heterozygous individual (for example Tt), do not get mixed and are seperated during gametogenesis, thus each gamate receive one allele for atrait and two types of gamaets are formed 50% gamate carry factor for domience (T) and 50% …
What is law of segregation with example?
Here’s an example of the law of segregation in action: In this imaginary lumpy species, the gene for L (more lumpy) is dominant to the gene l (less lumpy). Two heterozygous lumpies with genotype Ll (meaning they have one dominant allele and one recessive allele) mate and have children.
What stage of meiosis is law of segregation?
What happens during segregation?
Segregation basically means separation. During the gamete formation . alleles get separated from each other and each allele enters a single gamete. Separation of one allele does not affect the other.
What do you mean by law of segregation?
The law of segregation states that each individual that is a diploid has a pair of alleles (copy) for a particular trait. Each parent passes an allele at random to their offspring resulting in a diploid organism. The allele that contains the dominant trait determines the phenotype of the offspring.
What is the theory of segregation?
The Principle of Segregation describes how pairs of gene variants are separated into reproductive cells. The segregation of gene variants, called alleles, and their corresponding traits was first observed by Gregor Mendel in 1865.
What is the example of segregation?
Racial segregation did not only exist in the South, but was a national phenomenon. For example, the United States Armed Forces remained segregated until the 1950s—white and black units were kept separate, and black units were led by white officers. In 1954, the Supreme Court ruled in Brown v.
What is the principle of segregation Why is it important?
The principle of segregation is important because it explains how the genotypic ratios in the haploid gametes are produced. How are Mendel’s principles different from the concept of blending inheritance discussed in Chapter 1?
How did Mendel prove segregation?
Mendel proposed the Law of Segregation after observing that pea plants with two different traits produced offspring that all expressed the dominant trait, but the following generation expressed the dominant and recessive traits in a 3:1 ratio.
What is the law of segregation and independent assortment?
The law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. … The law of independent assortment states that the allele of one gene separates independently of an allele of another gene. This has has to do with 2 genes.
What is the Law of Independent Assortment?
The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop. Independent assortment of genes and their corresponding traits was first observed by Gregor Mendel in 1865 during his studies of genetics in pea plants.
Why is meiosis important for reproduction?
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Does law of segregation occur in mitosis?
Chromosome segregation is the process in eukaryotes by which two sister chromatids formed as a consequence of DNA replication, or paired homologous chromosomes, separate from each other and migrate to opposite poles of the nucleus. This segregation process occurs during both mitosis and meiosis.
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.
