<u>Answer:</u>
Although statements are not given in the question, we could make the most possible deduction as follows:
The allele for purple flowers is dominant whereas allele for white flowers is recessive.
<u>Explanation:</u>
According to the question,
- Purple flower plant was crossed with white flower plant.
- All offsprings have purple flowers.
Here we have one possibility that both parents were homozygous but in their own traits. <u>Purple flower</u> plants were "PP" and white <u>flower plants</u> were "pp" So, the <u>first progeny</u> (direct offsprings) would have "Pp". So, as per considerations, purple is dominant allele which will mask the recessive allele thus defining the color of all offsprings as purple. However, further cross of their generation will definitely end up into purple and white flowers (3:1) but this condition is not mentioned in the statement.
18 chromosomes would be in each of its gametes.
What are chromosomes?
the nucleus of most living cells contains a threadlike structure made of nucleic acids and proteins that carries genetic information in the form of genes.
There are 23 pairs of chromosomes in humans. The chromosome's distinctive structure helps to increase the integrity of the DNA while also keeping it securely packed with histone proteins to fit within the cell. For instance, a single cell's DNA will be 6 feet long when unraveled; from this, it is clear why each cell's nucleus needs to be packaged.
according to the given information:
number of chromosomes: 36
36√2 is 18
18 chromosomes would be in each gamete.

Complete question:
A geneticist crossed pure breeding black mice with pure breeding brown mice. All the 992 mice in F1 generation had black coats. When these mice were crossed, the yielded 961 black coated mice and 317 brown coated mice. How could you account for the ratio of black coated to brown coated mice in the F2 generation? Select all that apply
- The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
- The brown allele segregates together with the black allele and disappears in the F1 generation.
- The F1 female produced two kinds of eggs, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
- An approximately three-to-one ratio of black to brown coated mice in the F2 generation is accounted for by the black allele being dominant over the brown allele.
Answer:
- The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color. APPLIES
- The brown allele segregates together with the black allele and disappears in the F1 generation. DOES NOT APPLY
- The F1 female produced two kinds of eggs, half carrying an allele for black coat color, and half carrying an allele for brown coat color. APPLIES
- An approximately three-to-one ratio of black to brown coated mice in the F2 generation is accounted for by the black allele being dominant over the brown allele. APPLIES
