what is the difference between back cross and test cross?
Answer Posted / m. a. ansari
Back cross - crossing of hybrid (F1)either of its parents
(dominan / recessive).
AA x aa = Aa x AA / aa
Test Croos - Crossing of F1 with homozygous recessive
parent.
AA x aa = Aa x aa

In cucumbers normal leaves (N) are dominant to curled leaves (n) and elongated fruit (L) is dominant to spherical fruit and these genes are linked on the same chromosome. If a pure-breeding normal-leaved, elongated fruit cucumber is crossed with a curled-leaved, spherical fruit cucumber, what will be the phenotype of the F1? the phenotypic ratio of the F2?
Cystic fibrosis (CF) occurs with a frequency of about 1/2500 Caucasian newborns and is inherited as an autosomal recessive. A woman had an older sister die from complications of this disease. CF is not present among relatives of her husband. Both the woman and her husband have normal phenotypes. What is the chance this couple will have a CF child

Suppose you are heterozygous for a mutant beta-thalassemia allele. If the frequency of beta-thalassemia is 1/1600 persons, what is the probabilty that your prospective spouse is heterozygous for a mutant beta-thalassemia allele?
Explain in terms of gene product function how a mutant allele can be dominant? recessive?
Consider two linked autosomal genes. The dominant allele C of the first gene causes cataracts of the eye, whereas its recessive allele produces normal eyes. The dominant allele P causes polydactyly (an extra finger) whereas its allele (p) produces a normal number of fingers. A man with cataracts and normal fingers marries a woman with polydactyly and normal eyes. Their son has both polydactyly and cataracts and he marries a woman with neither trait. What is the probability that their first child will have cataracts and polydactyly?
