Which of the following statement is true about linkage?

It is a phenomenon in which more recombinants are produced in F2- generation. More parental combination are produced in F2 – generation. It is a phenomenon in which two chromosomes are linked. …

What is correct about linked genes?

Genes that are inherited together with the other gene(s) as they are located on the same chromosome. When a pair or set of genes are on the same chromosome, they are usually inherited together or as a single unit.

Which of the following statements explains the observation that closely linked genes?

Which of the following statements explains the observation that closely linked genes are typically inherited together? The genes are located close together on the same chromosome.

What are the different examples of gene linkage?

Linkage explains why certain characteristics are frequently inherited together. For example, genes for hair color and eye color are linked, so certain hair and eye colors tend to be inherited together, such as blonde hair with blue eyes and brown hair with brown eyes.

Which genes are linked?

When genes are found on different chromosomes or far apart on the same chromosome, they assort independently and are said to be unlinked. When genes are close together on the same chromosome, they are said to be linked.

Which of the following is a linked gene?

One of them is the SOX21 gene, which codes for the transcription factor SOX-21 protein. This protein is associated with baldness or hair loss. Other genes found in the Y chromosome include acetylserotonin methyltransferase, zinc finger protein, amelogenin, interleukin-3 receptor, etc.

Which of the following statements is not true regarding linkage groups?

2. Which of the following statement is NOT true regarding linkage group? Explanation: The linkage group refers to the group of genes physically linked together.

Which genes are most likely linked?

Most sex-linked genes are on the X chromosome, because the Y chromosome has relatively few genes. Strictly speaking, genes on the X chromosome are X-linked genes, but the term sex-linked is often used to refer to them.

How do you determine the distance between genes?

Which of the following statements about crossing over is most correct?

Correct answer:

Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.

What is a gene linkage map Mcq?

Clarification: Linkage is the tendency of two or more than two genes to stay together during the inheritance. It exists in two forms i.e. cis and trans. … The linkage maps are constructed by using recombination frequencies between genes.

Which of the following may not be applicable for linked genes?

Answer: Mendelian Independent Assortment Law may not be applicable for the linked genes of the same chromosomes.

Which of the following statements regarding crossing over?

Crossing-over disrupts the linkage between genes on the same chromosome. Crossing-over disrupts the linkage between genes on different chromosomes. Crossing-over produces new genetic combinations. Crossing-over produces non-parental chromosomes.

Which of the following statements is true regarding the process of crossing over?

Which of the following is true regarding crossing over? Explanation: … Crossing over occurs only between homologous chromosomes. Sister chromatids are situated to form a single chromosome; crossing over does not include recombination of genetic material within a single chromosome.

Does crossing over allows the reassortment of linked genes?

two homologous chromosomes, each consisting of two chromatids. Crossing-over occurs during prophase I of meiosis. Crossing-over allows the reassortment of linked genes. … Because it divides the diploid number of chromosomes into a haploid number, with only half the normal count.

Which of the following statement with respect to linkage is incorrect?

Knowledge of linkage helps to breeder to combine all desirable traits in a single variety.

Which of the following is false regarding crossing over?

Part B is false. Crossing over occurs between non-sister chromatids, meaning chromosomes that are not a part of the same homologous pair.

Which of the following statements is true chromosomes are classified into two categories?

Which of the following statements is true? Chromosomes are classified into two categories: the relationship chromosomes that determine gender and autosomes that determine non-gender related traits. one duplicated chromosome consisting of two sister chromatids. the possibility of nondisjunction increases.
