Which of the following best explains mendel’s law of segregation?

What aspect of meiosis best explains Mendel’s law of segregation?

Which of these descriptions of the behavior of chromosomes during meiosis explains Mendel’s law of segregation? The two alleles for each gene separate as homologous chromosomes move apart during anaphase I. Imagine a human disorder that is inherited as a dominant, X-linked trait.

Which statement explains Mendel’s law of segregation?

Mendel’s law of segregation states that allele pairs segregate equally into gametes during meiosis. This means that a gamete will have only one allele of any given gene, and that the probability of a gamete having one allele or the other is equal (and therefore ½, or 50%, for either allele).

What is Mendel’s first law of segregation?

1 Character Traits Exist in Pairs that Segregate at Meiosis. … This is the basis of Mendel’s First Law, also called The Law of Equal Segregation, which states: during gamete formation, the two alleles at a gene locus segregate from each other; each gamete has an equal probability of containing either allele.

What aspects of meiosis accounts Mendel’s law of segregation?

Explain how the events of meiosis account for the law of segregation an the law of independent assortment? the law of segregation separates homologous chromosomes. Independent assortment says homologous chromosomes are randomly separated into daughter cells. then the alleles separate.

What is the principle 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. From his data, Mendel formulated the Principle of Segregation. …

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 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 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 is segregation What is the result of segregation?

Segregation is the separation of alleles during the formation of gametes. What is the result of segregation? The result is that each gamete carriers only one allele for each gene.

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.

What are the laws of independent assortment and segregation?

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.

Why is Mendel’s Law of Segregation important?

The law of segregation ensures that a parent, with two copies of each gene, can pass on either allele. Both alleles will have the same chance of ending up in a zygote. In sexually reproducing organsisms, the genome is carried in two identical copies. A copy was inherited from each parent, in the form of a gamete.

What are the 3 laws of inheritance?

The Mendel’s laws of inheritance include law of dominance, law of segregation and law of independent assortment.

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?
