Although we pass on the same genes (units of heredity) to our offspring as we inherit from our parents, we do not pass on the same chromosomes. Why is this true?

Answer #1

Meiosis is an essential event in sexually reproducing organisms.
It generates new variants in the progeny by two mechanisms
1. Independent assortment of chromosomes
2. Crossing over between non-sister chromatids of the homologous pair of chromosomes

Due to recombination, the maternal and paternal genomes are recombined (Mixed). Hence, the gametes that an individual produces contains recombinant chromosomes. Hence a person cannot transmit the same chromosome that he/she inherited from his/her parents.

In humans the sex of an individual is determined by the sex chromosomes that they inherit. All individuals carry two sex chromosomes, but males carry a so-called X and a Y chromosome (and are thus called XY) whereas females carry two X chromosomes (and are thus called XX). When a male and female produce an offspring, each gives the offspring one of its sex chromosomes, chosen with equal probability. Thus, a child always inherits an X chromosome from its mother...

Probability and Genetics Lab In heredity, we are concerned with the occurrence, every time an egg is fertilized, of the probability that a particular gene or chromosome will be passed on through the egg, or through the sperm, to the offspring. As you know, genes and chromosomes are present in pairs in each individual, and segregate as they go into the gametes (egg and sperm). There are two possible genes (alleles) that the egg or sperm might obtain from each...

(5 pts) Genes D and E are located in the Drosophila genome. DE·DE females are crossed with de·de males to produce F1 flies that are heterozygous for both traits. What gametes do each of these parents make? F1 females were crossed with de·de males, and 2000 flies were examined. What gametes do each of these parents make? What are the possible genotypes of the offspring produced from the cross in part B? If the genes were sorting independently (not linked),...

Our company produces a product that is currently sold for $70 per unit. We are considering processing it further into an upgraded version of the current product. If we do so, we can sell the product for $90, we will incur additional costs of $395,000, and we can sell 20,000 units Which of the following is true? Sell now at $70 since doing so will maximize operating income. Process further because operating income will increase by $5,000. Process further because...

Instructions St. Augustine in the 5th Century held that we are free to make choices in life. This is the idea of free will. It may seem at first glance odd for a religious thinker to say that we have free will. After all, if God exists, then God created all things. God knows already what we will do. God can cause anything to occur. If we cause things to occur, that seems to be a limitation on the power...
