Sweet pea plants have a diploid (2n) chromosome number of 14. Which of the following best explains how the sweet pea plants in the parental generation produce F1 offspring with 14 chromosomes? Meiosis II and IIII lead to the formation of cells with 7 chromosomes.

Answers

Answer 1

The option "C" holds best explanation for how the sweet pea plants in the parental generation produce F1 offspring with 14 chromosomes.

how the after fertilization of parental sweet pea plants got offspring with 14 chromosomes?

Seven chromosomal cells are created by meiosis I and II. Homologous chromosomes split during meiosis I. Sister chromatids split in meiosis II. When two cells unite during fertilisation, 14 chromosomes are produced in the baby.

What split up in meiosis 1 and 2?

Before meiosis II, homologous pairs of cells separate into chromosomes while in meiosis I. These chromosomes would be further fragmented into sister chromatids after meiosis II. Meiosis II does not involve genetic material crossing across or integrating between chromosomal pairs, whereas meiosis I does.

When do homologous chromosomes dissociate during meiosis?

In anaphase I, spindle fibres associated to the centrioles pull the sister chromatids pairs apart and to the opposite poles of the cell. Telophase I marks the termination of this initial cell division process.

Sweet pea plants have a diploid (2n) chromosome number of 14. Which of the following best explains how the sweet pea plants in the parental generation produce F1 offspring with 14 chromosomes?

A) Meiosis II and IIII lead to the formation of cells with 14 chromosomes. When two cells combine during fertilization, extra chromosomes are randomly broken down, leading to offspring with 14 chromosomes.

B) Meiosis I and II lead to the formation of cells with 14 chromosomes. When two cells combine during fertilization, extra chromosomes with recessive traits are broken down, leading to offspring with 14 chromosomes.

C) Meiosis I and II lead to the formation of cells with 7 chromosomes. During meiosis I, homologous chromosomes separate. During meiosis II, sister chromatids separate. Two cells combine during fertilization to produce offspring with 14 chromosomes.

D) Meiosis I and II lead to the formation of cells with 7 chromosomes. During meiosis I, sister chromatids separate. During meiosis II, homologous chromosomes separate. Two cells combine during fertilization to produce offspring with 14 chromosomes.

Who was a British spy in the Revolutionary War?Ann Bates was one of the most successful British spies of the war and a Loyalist sympathizer who taught in Philadelphia.Soon after accompanying her husband, a British soldier and gunsmith, to his position in New York in 1778, she started spying on the British. She met Major Duncan Drummond at the British camp, who took over for Major John André as the British commanding general's intelligence head. For the British Army, Drummond suggested using Bates as a spy.Women were frequently permitted unrestricted access to military camps at the time since it was generally believed that they were incapable of comprehending military concerns or the significance of what they saw or heard. As a result, Bates found it simple to enter the lines of the Continental Army and inform the British on troop movements, supplies, and the preparation of upcoming operations. Even two famous individuals gave her passes: General Charles Scott, who was then in charge of Washington's intelligence, and General Benedict Arnold, who was still in the early stages of his own spying.

Which characteristics of life does an automobile possess?

Answers

Metabolism is characteristics of life , an automobile possess

Why are automobiles regarded as non-living things?

An automobile appears to be alive since it can move and utilize energy, yet it cannot reproduce. To be considered alive, something must exhibit all five aspects of life. Automobiles, water, fire, and mountains are a few examples of nonliving things.

The only trait of life that an automobile might possess is metabolism, which enables it to consume and utilize energy (such as gasoline or diesel) while exhaling waste products like exhaust and water. It lacks any other aspects of life and is unable to accomplish this on its own.

In the failing light, the old grandmother sits in the kitchen with the child beside the Little Marvel Stove, reading the jokes from the almanac, laughing and talking to hide her tears. She thinks that her equinoctial tears and the rain that beats on the roof of the house were both foretold by the almanac, but only known to a grandmother. The iron kettle sings on the stove. She cuts some bread and says to the child, It's time for tea now; but the child is watching the teakettle's small hard tears dance like mad on the hot black stove, the way the rain must dance on the house. Tidying up, the old grandmother hangs up the clever almanac on its string. Birdlike, the almanac hovers half open above the child, hovers above the old grandmother and her teacup full of dark brown tears.
