A population of beetles in the species Dwayne therock (I made this up) are living in a rotting log in a forest. In these beetles, color is controlled by 1 gene. There are two alleles - R for Red and r for orange. this is an autosomal trait with complete dominance Questions part 1 1. What are all the possible genotypes a red beetle could have? (list them all) 2. What phenotype would a heterozygous beetle have?

1.) Consider flower color in a hypothetical population of 7,000 flowers, red flowers (4,000), blueflowers (2,000) are dominant over pink flowers. If there are 1,000 pink flowers, find thefollowing:a. Frequency of dominant (red flower) alleleb. Frequency of recessive (pink flower) allelec. Frequency of each genotype (homozygous dominant, homozygous recessive,heterozygous)d. Make a Punnett square and use the rule of multiplication.

In Hereford cattle, the phenotypic expression of coat pattern called line-back (a white line down the center of the back, extending almost to the tail) is considered undesirable. The gene which causes line-back is recessive and autosomal. If 7 cows out of 100 cattle express this trait, what is the allele frequency for this trait? If the line-back cows are not included in the mating population (W22=0), how many line-back cows will be found in the next generation? (Assume 100 cows in the next generation.) can u ansewer the second question
Skin colour in dolphins is determined by a single gene showingincomplete dominance giving rise to 3 phenotypes Brown, Pink &White. A survey of a large population of dolphins was carried outand the phenotypes recorded. However a student who had some.of the data stored on their phone fell overboard and unfortunatelythe data was lost. The only data saved was that the brownhomozygous dominants (BB) were 64% of the population.a) What would be the percentage of pink heterozygotes and whitehomozygotes?b) What percentage of the gametes that give rise to the nextgeneration of dolphins in this population will contain the b allele?
The allele for a widow's peak (hairline) is dominant over the allele for a straight hairline. In a population of 650 individuals, 16% show the straight hairline. How many individuals would you expect to be homozygous dominant and heterozygous for the trait?
Figure 19.2 In plants, violet flower color (V) is dominant over white (v). If p = .8 and q = 0.2 in a population of 500 plants, how many individuals would you expect to be homozygous dominant (VV), heterozygous (Vv), and homozygous recessive (vv)? How many plants would you expect to have violet flowers, and how many would have white flowers?

Color blindness in humans is an X-linked recessive trait. Approximately10% of the men in a particular population are color blind.a. If mating is random with respect to the color-blindness locus, what isthe frequency of the color-blindness allele in this population?b. What proportion of the women in this population are expected to becolor blind?c. What proportion of the women in this population are expected to beheterozygous carriers of the color-blindness allele?
Scenario A In goats, black fur is dominant to red fur. The gene for this trait can be described as Bb (if you forgot why this is so, go back and reread the background information at the beginning of this exercise). A homozygous black female goat (nanny) is crossed with a heterozygous male (billy). 1 What is the genotype of the nanny? What is the phenotype of the nanny?
