Cells become haploid cells towards the end of meiosis ll
Answer:
The genotypic ratio shows the number of times a characteristic of an organism will be seen in the offspring when genes for certain traits are crossed. ... The genotypic ratio for this cross is written 1:2:1. In animals and plants, each gene has 2 alleles or variations, one from each parent

Answer: Answer is below in the explanation.
Explanation:
As shown in the animation from my school, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes.

Answer:
The correct genotype would be-
mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.
Explanation:
Listing the genes in the way that they indicates the real combination of alleles is the genotype of individual.
Ability to roll your tongue is a dominant character which has a dominant and a recessive gene. Assume that the dominant allele ‘R’ is for the ability to rolling tongue and the recessive allele ‘r’ for unable to rolling our tongue. As we know mother can not roll her toungue she must have homozygous recessive alleles that means she has two copy of recessive allele. The father could posess any combination of these alleles: RR (homozygous dominant), or Rr(heterozygous dominant).
Thus, the correct genotype would be
mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.
