WebEnter a predicted ratio for a hypothesis that you want to test. For example, if you want to test a 4:1 ratio, enter a 4 in the first box under the Hypothesis column and enter a 1 in the second box. To evaluate the effects of sex on this cross, simply type a 4 in each of the first two boxes, and type a 1 in each of the last two boxes. WebThis phenomenon is called genetic linkage. When genes are linked, genetic crosses involving those genes will lead to ratios of gametes (egg and sperm) and offspring types that are not what we'd predict from Mendel's law of independent assortment. Let's take a … Basically, it is the enzymes that produce the phenotypic character. In the nucleus, …
WebCodominance A. In cattle, codominance of the allele for a red coat (R) and the allele for a white coat (W) results in offspring with a roan coat (RW); that is, a coat with both red and white hairs.

Weba hybrid means that the offspring is heterozygous. in regular mendelian genetics, its genotype would be a dominant allele and a recessive allele (ex. Aa). in incomplete dominance and codominance (non-mendelian genetics), it would mean that it has two different alleles (ex. AB or A^1 B^1). ( 2 votes) Upvote.
