Answer:
It contains 46 chromosomes and It contains 23 chromosomes
Step-by-step explanation:
Among the statements you provided:
"Each chromosome contains 23 genes" is not correct. The number of genes on a chromosome can vary significantly, and it is not a fixed number. Some chromosomes may have more genes, while others may have fewer.
"It contains 46 chromosomes" is generally correct. Humans typically have 46 chromosomes, with 23 pairs. One chromosome in each pair is inherited from each parent, for a total of 23 from the mother and 23 from the father.
"It contains 23 chromosomes" is also correct in a sense. Humans have 23 pairs of chromosomes, for a total of 46 individual chromosomes.
"Each strand contains the chromosomes from one parent" is not accurate. Human DNA is a double helix, with each strand containing genetic information from both parents. In other words, each chromosome has one homologous chromosome from each parent.
So, statements 2 and 3 are correct, while statements 1 and 4 are not entirely accurate.
