When an organism has the dominant phenotype, then its genotype can be either heterozygous or homozygous dominant (you can’t tell by looking at it). In order to find out we must do a test cross using an homozygous, recessive organism. For example: In Dalmatian dogs, the gene for black spots is dominant to the gene for liver colored spots. If a ...
In pea plants, round (R) is dominant to wrinkled (r). A heterozygous female is crossed with a wrinkled male. Make a Punnett Square to determine the possible offspring.
Mendelian Genetics: Mendelian genetics describes the patterns of inheritance of traits from one generation to the next, based on the work of Gregor Mendel. It includes concepts such as dominant and recessive alleles, Punnett squares, and genetic crosses.
Some traits follow predictable inheritance patterns. For example, for pea height, tall (T) is dominant, and short (t) is recessive. All that means is this: • Dominant: it takes one T allele to cause the tall phenotype, no matter what the other allele is. • Recessive: it takes two t alleles to cause the short phenotype.
Can you think of a trait you have inherited? How about a trait that you have acquired by learning or tradition? Play this memory game with your family or group to discover some common traits and traditions!
