Define these 4 terms: alleles, gene expression independent assortment, and chromosomal segregation. Tell how they are related to one another in terms of genetics and meiosis.
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
Define these 4 terms: alleles, gene expression independent assortment, and chromosomal segregation. Tell how they are related to one another in terms of genetics and meiosis.
Genetics is the branch of biology which deals with the study of genes, heredity and variation in characteristics which are inherited in organisms.
Allele is defined as a pair of genes or series of genes on a chromosome which determines the hereditary characteristics. It is located on the same locus on a particular chromosome and controls the same characteristic of chromosome like blood type or color blindness. They are also called as allele morphs. There are two forms of alleles: dominant and recessive. Dominant alleles are expressed over recessive alleles and recessive allele will express only in the absence of dominant allele.
Gene expression is defined as a process by which the information or instructions in the DNA is converted into the functional product like protein or RNA. It is an extremely regulated process which makes a cell to respond its changing environment. Two main steps involved in transcription and translation. Transcription is a process by which DNA is converted into RNA which is then translated to form proteins (translation).
