Answer:
25% chance curly (HH) 50% chance wavy (HH') and 25% straight (H'H')
Explanation:
Make a Punnett square like so to find the probability of each hair type for the offspring of two wavy haired people
Binary fission, is an asexual reproduction by, and it is when the body splits into two new bodies. In the process of binary fission, an organism duplicates its genetic material, (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA. Hope this helps. c;
RrXtXt×RrXTY is representing the cross between the white eyed female and red eyed male.
Option D
<h3><u>Explanation:</u></h3>
The genes that are discussed here both are completely dominant over their recessive alleles. In the autosome, the dominant R gene is responsible for red eye and recessive r gene is responsible for sepia eye. But in allosome, the dominant T gene allows the eye colour to be expressed and the recessive t gene doesn't allow eye colour to be expressed and makes it white.
As the female do have 2 X chromosomes and the female is white eyed, then both the chromosomes of female have t gene.
As the male is red eyed and have one X chromosome, so the male must have atleast one R gene in autosome to make the eye colour red and must have T gene in his X chromosome to make it appear in phenotype.
So the most possible cross that is given here is RrXtXt×RrXTY.
The molecular clock is a scientific technique which presents a means of estimating evolutionary rates and timescales using genetic data. It uses mutation rate of biomolecules when two or more life forms diverged to estimate the time. Answer is B.
Answer:
72, because you just multiply by 2
