Such organisms could be either homozygous dominant or homozygous recessive. In such organisms, two traits can be expressed — either dominant or recessive. The literal meaning of homozygous = homo + zugos (Greek words, meaning “same”, “joined together” Humans are diploid organisms and possess...
Also, chickens with the dominant trait for skin color will have white skin, while those with recessive genotypes will have yellow skin. What are dominant traits? Dominant traits are observable characteristics expressed if an organism has a homozygous dominant or heterozygous genotype. In other words...
In instances wherein the dominant allele is absent, the expression of the recessive allele will occur. If the dominant allele is labeled as “A” and the recessive allele, “a”, three different genotypes are possible: “AA”, “aa”, and “Aa”. The term “homozygous” is used to ...
A homozygous recessive genotype could be "aa" for seed texture, where the pea plant would express the trait of wrinkled seeds. In short, an organism's phenotype or physical expression of some genes can easily express only the dominant trait as long as there is at least one dominant allele ...
Give examples of heterozygous, homozygous recessive, and homozygous dominant alleles. Mendelian Genetics: Gregor Mendel is credited as the father of modern genetics. He was the first to discover that the patterns of the passage of traits from parents to offspring could be predicted....
Monohybrid crosses are usually performed to determine the genotypes of offspring of homozygous individuals. The hybrid produced from this cross helps in the identification of the dominant genotype in the allele. Even though monohybrid crosses are often associated with homozygous genotypes, these are also...
Suppose a gene has two alleles, one of which is dominant over the other. An individual whose genotype is homozygous for the dominant allele has which of the following? a. Two copies of the allele that determines phenotype whenever the allel...
If a red homozygous snapdragon is paired with a white snapdragon (which is also homozygous), the hybrid result would be a pink snapdragon. Here’s how it the partial dominance looks when broken down: The genotypes are Red (RR) x White (rr) = Pink (Rr) ...
In a monohybrid cross, a single genetic trait or character is studied by crossing two homozygous dominant and recessive parents for the said character. The second type of Punnett square is the 4×4 squarewith 16 boxes. This is the larger box that deals with more than one character. ...
UsingPunnett squaresyou can work out the probabilities that children of the parents in each example will have particular phenotypes and genotypes. Monohybrid Crosses Dominant B and recessive b B b BBBbB bBbbb In this case, the probablity of a child having ...
