simple Mendelian genetics...right-handed is the dominant allele (R), left-handed is recessive (r). you can figure it out using a Punnett square.
RR, Rr = RH kid
rr = LH kid
RR + RR = 100% RR -> all RH kids
RR + Rr = 50% RR, 50% Rr -> all RH kids
Rr + Rr = 25% RR, 50% Rr, 25% rr -> 75% RH kids, 25% LH kids
rr + rr = 100% rr -> all LH kids
to be LH, you have to have left-handedness somwhere in the family. however, you can be LH and neither your parents or grandparents would have to be.

What cause handedness?
Handedness is believed to be influenced by a combination of genetic factors and environmental influences. While the exact cause is not fully understood, studies suggest that handedness may be determined by a complex interplay of genetics, prenatal development, and brain wiring. Additionally, some researchers believe that hormonal influences in the womb may also play a role in determining handedness.
What is the study of inheritance triats called?
The study of inheritance traits is called genetics. It focuses on how traits are passed from parents to offspring through genes and how variations in genes contribute to different traits and characteristics in individuals.
How genes are passed from parents to offspring is the study of what?
It is genetics.
What is the study of genes and inheritance an traits is called?
The study of genes, inheritance, and traits is called genetics. This field explores how traits are passed from one generation to the next through the transmission of genetic information encoded in DNA. Genetics encompasses various sub-disciplines, including molecular genetics, population genetics, and quantitative genetics, each focusing on different aspects of heredity and variation.
What field of genetics is the oldest?
The oldest field of genetics is classical genetics, which emerged in the early 20th century with the rediscovery of Gregor Mendel's work on inheritance patterns in pea plants. Mendel's principles laid the groundwork for understanding how traits are passed down through generations. This field primarily focuses on the study of heredity and the roles of dominant and recessive alleles, setting the stage for modern genetics and the exploration of molecular genetics.
What are your genetics?
The characteristics that your parents passed on to you through your genes
Are allergies passed down from parent to child?
they are through genetics
The study of how traits are passed from parent to offspring?
This is known as genetics. It involves the study of how genes are inherited and how they contribute to the physical and behavioral characteristics of organisms. Genetics helps to explain variations among individuals and how traits are passed down through generations.
Is crohn's disease transferrable?
It may be passed down to the person's children through genetics. But it is not contagious.
How many breeds of werewolves are there?
there are enchanted werewolves, made through the obvious, hereditary, which is passed through genetics, and a couple others.
Is left handedness inherited?
Left-handedness can have a genetic component, but it is not completely determined by genetics. Research shows that having one or both parents who are left-handed can increase the likelihood of a child being left-handed, but environmental factors can also play a role in the development of handedness.
How would any changes in a mammal be passed on from generation to generation?
Through DNA, Genetics and Natural Selection.
What cause handedness?
Handedness is believed to be influenced by a combination of genetic factors and environmental influences. While the exact cause is not fully understood, studies suggest that handedness may be determined by a complex interplay of genetics, prenatal development, and brain wiring. Additionally, some researchers believe that hormonal influences in the womb may also play a role in determining handedness.
How is the characteristic yellow skin passed on in tomatoes?
Through genetics. The yellow skin is coded for in the DNA that outlines the tomatoe's genetic information, and that is passed down.
What is the inheritance of sex-linked traits through meiosis and how it relates to genetics?
The inheritance of sex-linked traits through meiosis is where chromosomes are replicated. This relates to genetics in that the traits are passed on to divided cells from the parent cell.
What is the inheritance of sex linked traits through meiosis and how it relates to genetics?
The inheritance of sex-linked traits through meiosis is where chromosomes are replicated. This relates to genetics in that the traits are passed on to divided cells from the parent cell.
Why do we call Mendel the Father of Genetics?
Gregor Mendel discovered how genes were passed on from parent to offspring through his experiments.
