Mendel’s Law of Independent Assortment is another fundamental principle of genetics proposed by Gregor Mendel. This law describes how genes located on different chromosomes are inherited independently of each other. Mendel’s Law of Independent Assortment State:The Law of Independent Assortment states that alleles for different traits assort independently of one another during the formation of … Read more
Mendel’s Law of Segregation is one of the fundamental principles of genetics, proposed by Gregor Mendel in the mid-1800s. It describes how alleles for a given trait are inherited from one generation to the next. Here’s a clear explanation of the law: Mendel’s Law of Segregation State:The Law of Segregation states that each individual has … Read more
Genes play a crucial role in protein synthesis, which is the process by which cells create proteins. These proteins are essential for almost every function in the cell, including catalyzing biochemical reactions, providing structure, and regulating processes. The process of protein synthesis can be broken down into two major stages: transcription and translation. 1. Transcription … Read more
Genes and Alleles: Genes and alleles are fundamental concepts in genetics that explain how traits are inherited and expressed in living organisms. 1. What are Genes? A gene is a segment of DNA (or RNA, in some cases) that carries the instructions for making proteins or RNA molecules that influence the characteristics (traits) of an … Read more
Chromatin is a complex of DNA and proteins that makes up the chromosomes in the nucleus of a cell. It plays a key role in packaging the DNA into a compact form so that it can fit inside the cell nucleus, and also regulates gene expression and DNA replication. Here’s the composition of chromatin material … Read more
Genes control the inheritance of characteristics (or traits) through a process known as genetic inheritance, which is governed by the transfer of genetic material (DNA) from parents to offspring. Here’s how genes control this inheritance: Genes and Alleles: Genes are segments of DNA that carry the instructions for making proteins, which influence the traits of … Read more
Heterozygous: Aa, Bb Homozygous: AA, ss Same phenotype: BB and Bb (if B is dominant) Related Questions: Write the differences between: Name sources of variation. Give examples of artificial selection. What kind of gametes would be produced by organisms having the following genotypes? Two white sheep produce a black offspring. What must the parents’ genotype … Read more
a. Which variety was more common when there was more air pollution? Give a reason as well. Dark-colored moths were more common due to industrial melanism, as they blended better with polluted, dark tree bark, avoiding predation. b. Which variety is more common in England nowadays? Give a reason as well. Light-colored moths are now … Read more
The parents must be heterozygous (Bb). The probability of a black offspring (bb) is 25%. Related Questions: Write the differences between: Name sources of variation. Give examples of artificial selection. What kind of gametes would be produced by organisms having the following genotypes? Name the structure through which the exchange of gases can take place … Read more
AaBB: AB, aB aaBB: aB, aB AAbb: Ab, Ab Related Questions: Write the differences between: Name sources of variation. Give examples of artificial selection. Two white sheep produce a black offspring. What must the parents’ genotype for colour be? What is the probability that the next offspring will be black? The diagram shows two … Read more
