(a) If a normal human cell has 46 chromosomes , how many chromosomes will be there in a human (i) sperm cell, (ii) zygote ? (b) What sizes of plants are produced if both parents have genes Tt? Q. If zygote of an angiosperm has 15 pairs of chromosomes, what is the number of ...
Question: How many chromosomes do onions have? Answer and Explanation: Learn more about this topic: Comparative Genomics: Chromosome Number from Chapter 7/ Lesson 3 5.5K In comparative genomics, the number of chromosomes is examined to see the genes that are passed down in different organisms. ...
A chromosomally normal zygote has 23 pairs of chromosomes. At the time of fertilization, it has only one cell (made when the sperm cell combines with the egg cell). "The genetic information in these cells then causes the zygote to start dividing," says Dr. Richlin. Essentially, the single...
At fertilization, the sperm cell unites with the egg cell toform a diploid zygote (2n=46). This is crucial so that the total number of chromosomes inside the cells of the human body remains constant at 46 and the number of chromosomes can stay the same across human generations. ...
a zygote is formed, it inherits half of its chromosomes from the mother and half from the father, but these chromosomes come together in a new pattern that isn’t present in the mother or father, which makes it entirely unique. Crossing over of parental chromosomes in the zygote results ...
A second problem they dealt with is that in many cases where the husband is “infertile” his sperm count is simply low, but he is definitely not “sterile.” An extremely fecund woman may thereby become pregnant easily by a man who is extremely infertile. Thus, in any group of...
What would be the result of a nondisjunction of chromosome 21 in a zygote that is 46,XY? Explain. In trisomy 21 or Down syndrome, cells are formed with an uneven distribution of chromosomes inside their cells. This outcome ...
Here is EVIDENCE from a culture where breeding with your siblings and cousins is acceptable by their “god”.How did the Bible writers over 3000 years ago know about this? Consider that there was no modern science in the human culture. (Not one mention of chromosomes, DNA, nor mutagens) ...
