In particular, it explains that humans have one fewer chromosome pair in their cells than apes, due to a mutation found in chromosome number 2 that caused two chromosomes to fuse into one.

The X chromosome carries at least 150 genes linked to intelligence. Since the mother has two X chromosomes to pass along while the father only has one, the mother’s contribution to the child’s ...

McClintock and Creighton followed the "knob" on a specific chromosome in maize gametes and correlated this physical structure with specific phenotypes. How does DNA recombination work? It occurs ...

“This work is really important because the X chromosome has largely been excluded from genetic studies in the past,” said Amy ...

All men and only men have a Y chromosome. This biological fact allows us to trace back in time a direct, largely unchanged genetic line of inheritance from father to son. Every person, male or ...

Some chromosomes, such as B chromosomes, can increase their inheritance rate to their own advantage. These extra chromosomes are found in many plants, animals, and fungi and rely upon various ...

Sex determination at birth is decided on the chromosomes the baby has. A female has two X chromosomes, whereas a male has one ...

Some chromosomes, such as B chromosomes, can increase their inheritance rate to their own advantage. These extra chromosomes ...

And for that, she got a Nobel prize all to herself, which is no small feat either. Human chromosomes, long strands of DNA by Steffen Dietzel CC BY-SA 3.0 McClintock was born on June 16 ...

Supernumerary B chromosomes, unlike A (standard) chromosomes, are not required for the normal growth and development of organisms and as of 2024, B chromosomes have been discovered in almost 3,000 ...

Increased risk for autism appears to be linked to the Y chromosome, a Geisinger Health System study has found, offering a new explanation for the greater prevalence of autism in males. The results ...
