A Punnett square can be used to predict genotypes (allele combinations) and phenotypes (observable traits) of offspring from genetic crosses. A test cross can be used to determine whether an organism with a dominant phenotype is homozygous or heterozygous.Females have two X-chromosomes. Males have one X and one Y-chromosome. With both an X and a Y-chromosome, males inherit both X and Y-linked traits, while females only inherit X-linked traits. Since males have only one copy of each sex chromosome, they are hemizygous for all sex-linked genes, and they always express the phenotype * of the …The probability of the offspring having the dominant phenotype for “A” is 3/4. 1/4 x 3/4 = 3/16.

Punnett Square: Dominant and Recessive Traits. Every human on earth is a combination of two sets of genes: your mother’s and your father’s. These genes created a blueprint for you, and they make you unique. Genes lead to different traits, or characteristics, such as brown eyes or blue eyes. Parents passing on their genes to their offspring ...The phenotype is what that individual looks like. This can be illustrated with a simple chart. It's called a Punnett's Square. We'll use the example of tall pea plants verses short pea plants. When two tall dominant plants breed, all the offspring are tall dominant. When two hybrid plants breed, one in four of the offspring are short. Punnett squares that show two or more traits illustrate the idea that alleles for different traits (different genes) are segregated independently of each other.

You know you're looking at three traits. You're interested in the offspring. So you do a punnett square branch diagram and you ride out all the little eels and figure out what the gina types of the offspring are.

Each box within the square represents a unique genetic combination resulting from the assortment of alleles during gamete formation and ...What a punnett square does is that it tells you, given the genotypes of the parents, what alleles are likely to be expressed in the offspring. The classic example of this would be Mendel's peas. For pod color, the pea plants had two different alleles: Green and Yellow. Yellow is dominant to green. Hence, let's call the yellow allele "Y" and the ...A self-cross of one of the Yy heterozygous offspring can be represented in a 2 × 2 Punnett square because each parent can donate one of two different alleles. Therefore, the offspring can potentially have one of four allele combinations: YY, Yy, yY, or yy (Figure 1).
