Answer: The correct answer is 25%.
As per the question, genetic disorder is caused by recessive allele. This means that that genotype of the person having the recessive disorder is gg.
A dominant allele ( depicted by capital letter like G in this case) always masks the expression of recessive allele.
A recessive disorder will only be caused when the person is homozygous for the recessive allele ( like in this case gg is the genotype that will cause the disease.
In the given question, genotypes of parents is Gg and Gg.
The chances that their children will inherit the disorder is 25%. Refer punnett square.
Ans. (B). Mutated gametes (sex cells) fuse to create offspring.
Genetic mutations or germline mutations can be defined as permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other, when a mutated sperm or mutated oocyte (gametes) get fertilized with other oocyte or sperm.
A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, as single-celled zygote divides and produce all of the cells in that organism.
Thus, the correct answer is option (B).
so i believe the answer is c and if not or if u can select more then 1 i would also choose b just encase but overall the answer is c i believe
Answer:
D) Chromosomes can align in metaphase I in multiple possible arrangements in a process called independent assortment.
Explanation:
One cell produces two genetically identical daughter cells is both mitosis and meiosis.
