2) The gene for hair texture exhibits incomplete dominance. H is the allele for curly hair and h is the allele for straight hair. The heterozygous condition for this gene produces wavy hair. If a wavy-haired man and a straight-haired woman decided to have children, what would be the expected genotypic and phenotypic ratios of the children? 3) In Drosophila (fruit flies), a gray body color is dominant to black, and a pink eye color is dominant to red. If two flies are crossed that are each heterozygous for both traits, what would be the expected genotypic and phenotypic ratios of the offspring?

4) Two white mice were mated and over several years produced 13 black and 38 white offspring. Assume that the color gene is located on an autosomal chromosome, not a sex-determining chromosome (i. e. this is not a sex-linked trait).

What are the genotypes of the parents?

b) What is the expected genotypic ratio of their offspring?

5) In horses, black (B) is dominant over the allele for chestnut color (b). A chestnut mare is mated to a black stud. The first colt born is chestnut.

a) What are the genotypes of the three horses involved (mare, stud, colt)?

b) What percentage of their offspring will be expected to be black? What percentage
would we expect to be chestnut?

6) Hemophilia A is sex-linked recessive disease.

a) Two normal parents have their first son, who is found to be a hemophiliac. What are the genotypes of the parents, and the expected genotypic and phenotypic ratios of their future children? (Remember, this is a sex-linked disorder)

b) It is said that sex-linked diseases are often passed from a mother to her son. Explain
this statement.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.

explanation:

i believe the correct answer is the virus gets an envelope that contains host molecules when it leaves the host cell.

explanation:

during the bidding/release stage of a virus, it encapsulates itself with part of the membrane of the host cells in this case the cells of the monkey and is the reason as to why the scientist found the genetic material of the monkey on the viral cell surface.

further explanation

to understand this answer, we have to know the cycle a virus undergoes to replicate. a virus is basically a bunch of genetic material enclosed in a capsule and lacks any machinery or organelles to ensure their survival so they must enter a host cell in order to get the environment needed to survive. some viruses enter and lyse(destroy) the host cell after they have replicated and undergo the lytic cycle while some enter and leave the cell intact after replicating and these undergo a lysogenic cycle. to enter the cell, they undergo the first process called attachment by binding to specific receptors and co-receptors on the surface of the host cell. after attaching to the cell, they start the second phase called penetration where virus enters or is engulfed whole by the host cell through a process called endocytosis. it is the same process that a cell takes up materials it needs or pathogens around it. uncoating of the virus then happens after the virus has been engulfed and is the third stage. the virus then undergoes releasing of its genetic material in the host's matrix.   the materials then enter the nucleus and undergo biosynthesis by adding themselves in strands of rna being translated and then copies of the virus are produced in addition to the host genetic material. the material/newly formed viral material then undergoes assembly inside the host cell and form a capsule around them. the virus undergoes the last release/budding stage by binding to the host membrane and pushing outwards. in doing so when they tear away from the host membrane, they pick up the genetic material from the membrane of the host cell to form their envelope.
