Females with XY karyotype with 46 chromosomes is a type of disorder known as Swyer syndrome or XY gonadal dysgenesis. They have normal external... View Article
We are diploid organisms. Each cell of our body contains two sets of chromosomes, one from each parent. So, we inherit 23 chromosomes from each... View Article
A test cross is done between a dominant phenotype and a recessive phenotype to estimate the zygosity of the dominant phenotype. The two-point... View Article
Linked genes are present on the same chromosome and do not segregate independently while gamete formation, so they do not follow the Mendelian... View Article
If we know the type of inheritance of the gene such as dominant, recessive or sex-linked, we can predict the pattern of inheritance through... View Article
Biological inheritance is another term for heredity or inheritance. It is the passing of genes or characteristics from parent to offspring.... View Article
The recessive allele of a gene is that allele whose effect is masked by the dominant allele of that gene. The recessive allele is only expressed... View Article
If a trait skips a generation then it can be a recessive gene. Recessive genes can be found out by the pattern of inheritance through pedigree... View Article
The linked genes refer to tightly linked genes, which are present in close proximity and are often inherited together as a unit. Further... View Article
Both genes and chromosomes are made from DNA. Genes are the basic functional unit of heredity and comprise a small stretch of DNA. Chromosomes... View Article
Euploidy refers to the change in the complete set of chromosomes, i.e. loss or gain of the full set of chromosomes. It mostly occurs in plants.... View Article
Aneuploidy refers to loss or gain of one or more chromosomes. The two types of aneuploidy are monosomy and trisomy. Aneuploidy results due to... View Article
Chromosome mapping refers to the mapping of genes’ location on a chromosome. It is represented as an idiogram. It tells the position of... View Article
Thomas Hunt Morgan is known as the father of experimental genetics. He gave the experimental evidence of the chromosomal theory of inheritance.... View Article
In the human genome, chromosome 1 has the most genes. It has 2968 genes. Chromosome Y contains the least number of genes. i.e. 231. Further... View Article
Sutton and Boveri introduced the chromosomal theory of inheritance. Genes are responsible for the structure and function of every cell. Genes are... View Article
Genes are the basic functional units of heredity. Genes are a small stretch of DNA present on chromosomes. Genes code for functional proteins.... View Article
When the homologous pair of chromosomes possess different alleles of a gene, then they are known as heterozygous for the gene. The two alleles of... View Article
The functional segment of DNA is called genes. Gene is the segment of DNA that codes for a functional protein. Genes are inherited from parents... View Article
