which to mechanisms both contribute to genetic diversity Correct Answer-meisosis crossing over You have decided to spend money to have all of your potential breeders tested for the presence of a lethal allele. You then breed only those who tested negative. This is an example of: Correct Answer-marker assisted selection The mating of an individual with a dominant phenotype to one that is a known homozygous recessive id termed as: Correct Answer-testcross ______ mating is the mating amo...

define one genetic map unit ~ the physical distance between two genes that results in a 1% frequency of recombination In birds, sex is determined by ZW chromosome inheritance. Males are ZZ and females are ZW. Within pigeon populations there is a recessive, Z-linked allele that is lethal in embryos. What is the expected sex ratio in the offspring of a cross between a male that is heterozygous for the lethal allele and a wildtype female? ~ 2:1 male to female A recessive allele on the X c...
