In lizards, the gene for color and the gene for pattern are located on the same chromosome and exhibit recombination. the lined pattern allele (l) is recessive to the solid unpatterned allele (l), and the aqua color allele (b) is recessive to the blue color allele (b). geneticists cross a homozygous lined aqua lizard with a homozygous solid blue lizard. then, they carry out a testcross using the f1 progeny. the parental chromosomes for the testcross are given. identify all possible gametic haplotypes each parent can form.

The all possible gametic haplotypes that can be made are described below.

Explanation:

According to the question, F1 progeny was produced by crossing a homozygous dominant parent with a homozygous recessive parent. As per the question, cross is to be made with a heterozygous parent, which will have solid unpatterned allele and blue colour with a homozygous recessive i.e lined, aqua lizard.

The possible haploid gametes for the heterozygous parent would be BL, bl, Bl, bL and for homozygous parent would be all bl.
