Which of the below explains why trisomy is better tolerated in humans than monosomy? (Select all correct options). a. Loss of heterozygosity in monosomy b. Increased gene expression in trisomic cells is beneficial c. Reduced gene expression in monosomy d.The extra chromosome in trisomic cells is degraded
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.

d) synaptonemal complex
e) separese activity

(a)
<!--<SUMMARY-INTRODUCTION>-->
To Determine: If the given statement is true or false.
Introduction: Aneuploidy, a type of chromosomal abnormality, is highly prevalent in humans. When you have an extra copy of a chromosome, trisomy diseases develop. When one copy of a chromosome is absent, you have monosomy. Because a full missing autosome is almost always fatal, monosomies, which occur when the zygote obtains only one copy of a chromosome, are generally much less common than trisomies. Trisomy is more tolerated than monosomy for this reason.
<!--<ANSWER>-->
The given statement is true.
<!--</ANSWER>-->
<!--<EXPLANATION>-->
The loss of one parent's contribution to the cell is called the loss of heterozygosity. In this instance, it is brought on by monosomy or chromosome loss. In most monosomy situations, which are fatal, the foetus is not viable.
