What would be least likely to cause DNA damage in an individual suffering from xeroderma pigmentosum?
incandescent light bulbs
What is a tool for predicting genotypes of offspring?
In genetics a type of grid is used to show the gametes of each parent and their possible offspring and also called the checkerboard is used. The Punnet Square is named after Reginald Crundall Punnett an English geneticist.
If a homozygous dominant parent and a heterozygous parent are crossed what percentage of the offspring are expected to be homozygous dominant?
Rr
Where on the punnett square is the genotype of the parents places?
On the outside of the squares. So, an example would be: T t t t
If you made a Punnett square showing Gregor Mendels cross between true breeding short plsntd the square would show that the offspring had what?
the genotype of one of the parents

Based on this punnett square what percent of children would you expect yo be male?
what is the answer?
What system did Reginald Punnet invent for predicting when certain traits would appear?
The Punnett square.
How would set up a 3x3 punnett square?
this site it pathetic and doesnt answer anything well

How do you identify the genotyped of the parents when the Offspring has Rr Rr rr rr?
using a punnett square the parents would have to be Rr and rr
What is a Punnett square?
A Punnett square is a four-square diagram for showing the probabilities of an offspring to inherit a certain pair of alleles from its parents.For example,___T_ t__T | TT| Tt |t | Tt | tt |The Tt's (representing both parents' genotype) outside the Punnett square tell what the inner four squares will read. The inner squares tell what trait the parents' offspring might have.The Punnett square above shows that the offspring has a 25% chance of inheriting the homozygous dominant trait, 50% chance for heterozygous trait, and 25% for recessive.A Punnett Square takes two genotypes (discriptions of a gene) and determines the likelihood of four possible offspring carrying the genotypes. For example, blue eyes is a recessive gene. In order to have blue eyes, someone must have the genotype bb. The genotype BB or Bb would appear as brown eyes, the dominant trait. A Punnett Square of a blue-eyed organism and a brown-eyed organism (who carries the trait for blue eyes) would result in four potential offspring with the genotypes Bb, Bb, bb, and bb (two offspring have blue eyes and two have brown eyes but carry the blue-eyed trait). Punnett Squares allow scientists to predict POSSIBLE outcomes; they don't necessarily determine the offsprings' genotypes.
Why does a Punnett square use capital and lowercase letters?
The capital letters refer to the dominant gene or trait. The lower case letters are the recessive one, which means it is not as prominent in the new offspring when the two letters are combined. For example, the right handed trait would be the dominant one and would be a capital letter on the Punnett square, while the left handed trait would be lower case because it is recessive.
What is probability that wto heterozygous parents would have an offspring that produced round seeds?
75% because the recessive and dominant genes are corresponding and in a Punnett square it takes over.
