Some species of cacti are very tall and usually have two L-shaped ams, one on caci side. Let\'s say you lived near the Sonoran desert, where cacti are common and you happen to have one growing in your backyard. Your cactus has two arms but one is longer than tac ouica Now, assume that anm lengths in these cacti are controlled by a single gene with ams of the same length (A) being dominant to arms of different length. A. What was the genotype of your cactus? B. Could one of the parents of your cactus have had a phenotype with arms the same length? Explain your answer.

Solution

3) Let \' F\' be the allele for freckled phenotype and \'f\' be the allele for no frekles.

If the first child of the freckled woman and non frekled man is non frekled, then the mother ( frekled woman ) is a Heterozygote for the gene.

Genotype of Mother - Ff

Genotype of father - ff

Genotype of child - ff

The probability of 2nd child being non frecked is 0.5 or 50%

2) The genes for arm length in cactus might be codominant. Neither one is dominant and the offspring shows an intermediate phenotype
