While most people are familiar with the concept of their being different breeds of dogs and cats, it may not occur to them that are are also different breeds of other animals. Because these different breeds all belong to the same species, they are able to interbreed....
If the F1 progeny of two purebred organisms (AABB \times aabb) were testcrossed, what genotypes and phenotypes would you expect? What principle would you base your expectations on? a. If the F1 organisms were selfed, what phenotypic ratio would you expe ...
Aa is an example of a heterozygous genotype where the alleles are different. 6 What is an example of a homozygous genotype? AA or aa are examples of homozygous genotypes where the alleles are identical. 5 How does homozygosity affect biodiversity? High levels of homozygosity can decrease biodiver...
15). Many of the genotypes associated with colour-vision deficiencies are the result of a series of mutational steps away from ancestral gene arrays [38]. Polymorphisms in the L and M opsins give slight differences in spectral sensitivity. Blue cone monochromacy occurs when all the X chromosoma...
Mendel found that dominant traits – like purple flowers – are seen more often than recessive traits when purebred, homozygote peas cross. Recessive traits do not reappear until the F1(first-generation) hybrids mature and self-pollinate. Gregor Mendel also noted that dominant traits outnumber rec...
