Answer:
The probability of getting a dwarf and pink female is 1/2
Explanation:
In mice, dwarfism is caused by an X-linked recessive allele, and pink coat is caused by an autosomal dominant allele where coats are normally brownish.
A dwarf female from a pure line will have Xd Xd where d represent the recessive trait and the female is also brownish (pp).
A pink male from a pure line will be XPY where P represent the dominant allele but not a dwarf (D).
Xd Xd Xp Xp
XD XDXd XDXd XP XPXp XPXp F1 generation
Y XdY XdY Y XpY XpY
P XDXd x XdY XPXp x XpY
XD Xd XP Xp
Xd XDXd <u>XdXd</u> Xp <u>XPXp</u> XpXp F2 generation
Y XDY XdY Y XPY XpY
The probability of getting a dwarf and pink female is 1/2
1.
Anaphase. In <span>Anaphase the sister chromatids separate from each other to the opposite sides of the cells.
2. </span>
Chromosomes would not separate into two nuclei. <span>Mitosis is a process cell division, where one cell divides into two identical cells.
</span>
3.
Metaphase I. <span>Meiosis prophase I is the phase in which chromosomal crossing over occurs. The phase after prophase I is metaphase I.
4. </span>
Its body cells would have 36 chromosomes, and its gametes would have 18 chromosomes. <span>In the gametes, there are half of the number of chromosomes present in the body cell.
5. </span><span>
A species has to adjust rapidly to a changing environment. To adjust to the environment, crossing over is necessary, and it does not occur in mitosis, but meiosis.
6.
50 percent. Parents: Yy x yy
Offspring: Yy Yy yy yy
50 % is Yy and 50% is yy.

One parent had white eyes and the other was heterozygous for eye color. The ratio in the offspring is 50-50. The only possibility is the following:
Parents: Rr x rr
Offspring Rr Rr Rr Rr
8. </span><span>
Their fur will be a mixture of red and white hairs. The offspring will be heterozygous. They will have alleles for both red and white hairs and both will be expressed.

9. Not enough information.
10. <span>
Both of the parents' genotype must have been Pp. The genotype of the white plant is pp since it is recessive:
Parents: Pp x Pp
Offspring: PP Pp Pp pp
One of the four is white.</span>
Answer - A
The ratio of a child with clear skin with that of freckled skin is 1:2.
When genotype rr mates with genotype Rr, the following genotypes are expected:
Rr = clear skin dominant
rr= freckled skin
Answer:
Becomes completely enclosed by the region of the cell membrane into which the spikes and matrix protein are embedded
Explanation:
The viral capsid is a <em>protein shell that sorrounds a virus</em>, it serves as a criterion for the classification of viruses and <em>it encloses the genetic material of the virus and it has glycoproteins (spikes and matrix) embedded in it.</em>
