1. If we cross YyLl (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits)
P: YyLl x yyll
F1 generation: YyLl: 400 Yyll: 100 yyLl: 100 yyll: 400
Recombinant offspring are those children whose genes contain a non-parental allele combination (neither allele group is directly inherited from either parent). This happens when genes are located on the same chromosome but are so far apart from one another so that their alleles get crossed over during meiosis. In this case, Yyll and yyLl are the recombinant.
2. Calculation of distance between Y and L.
The numbers of the two recombinant types is 200 (100 Yyll + 100 yyLl) and 800 parental offspring.
Total number of offspring is 1000.
So: 200/1000*100=20 map units.
There is 20 percent recombinant offspring frequency.
It’s C. The start point of the cycle. I took this on my test
Answer:
Hydrogen bonding is caused by the tendency of some atoms in molecules to attract electrons more than their accompanying atom. This gives the molecule a permanent dipole moment – it makes it polar – so it acts like a magnet and attracts the opposite end of other polar molecules.
Answer: 1:2:1
Explanation:
The genotypic ratio is 1:2:1 whereas, the phenotypic ratio is 3:1 in the monohybrid cross. 2. Dihybrid cross: It is simple defined as the cross between two pairs of contrasting characters or parental alleles. Pea shape and color are used to conduct the dihybrid cross test.
