Answer:
Option C: Each granddaughter cell is haploid (n)
Explanation:
A diploid cell is a cell that contains two full sets of chromosomes. Meiosis is a process whereby the the original diploid cell produces 4 cells. These cells contain half of the genetic information that the diploid cell that underwent division contained. These cells that contain half of the chromosome types are referred to as haploids. These haploids have just one complete set of chromosomes whereas the diploid (as the name suggests) has two full sets. Examples of haploids are the reproductive, or sperm, cells that humans have. So essentially, haploids are the reproductive cells that are produced by meiosis.
Now, meiosis divides the cell by 4 whereas, through mitosis however, each cell splits into two. These two cells that were produced are completely identical to each other which means that they have the same number of chromosomes and are, therefore, haploids themselves as well.
Frogs are said to have two lives because they live on land and in water. When they are born, and then as they grow up to live on land.
Answer:
1/2
Explanation:
This question involves a single gene coding for feather color in chickens. The black allele (B) is incompletely dominant over the white allele (W). This means that the allele B will not mask the phenotypic expression of allele W, hence, a third intermediate blue phenotype (BW) will be produced.
According to the question, if two blue chickens are crossed i.e. BW × BW, the gametes B and W will be produced by each parent. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:
BB, BW and WW in the ratio 1:2:1
BB is black, BW is blue, WW is white. Hence, the probability of producing a blue chicken from this cross is 1/2.
