In a particular mammal, having long whiskers is a SEX-INFLUENCED trait; inFEMALES, long whiskers is dominant to short whiskers, and in MALES, shortwhiskers is dominant to long whiskers. Use W for the long whiskers allele and W*for the short whiskers allele.You cross a true-breeding FEMALE with long whiskers to a true-breeding MALE withshort whiskers. After intercrossing the F1 progeny, which of the following results areexpected for the resulting F2 progeny?a) None of these choicesb) 3/8 of the F2 progeny will be males with short whiskers.c) All of these choicesd) 1/8 of the F2 progeny will be females with short whiskers.e) 3/8 of the F2 progeny will be females with long whiskers.O f) 1/8 of the F2 progeny will be males with long whiskers.

Given Trait is sex influenced Long whiskers - dominant in female (recessive in male) Short…

In humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?
n guinea pigs, an allele for rough fur (R) is dominant over an allele for smooth fur (r), and an allele for black coat (B) is dominant over an allele for white fur (b). What would be the genotype of a guinea pig with smooth black fur? *
Use a Punnett square to predict the offspring in a cross between a dwarf pea plant (homozygous recessive) and a tall pea plant (heterozygous). What is the phenotypic ratio of the offspring?
More Crosses with Pea Plants: The Principle of Independent Assortment Determine the possible genotypes of the following parents by analyzing the phenotypes of their children. In this case, we will assume that brown eyes (B) is dominant to blue (b) and that right-handedness (R) is dominant to left-handedness (r). a. Parents: brown eyes, right-handed brown eyes, right-handed Offspring: 3/4 brown eyes, right-handed 1/4 blue eyes, right-handed b. Parents: brown eyes, right-handed blue eyes, right-handed Offspring: 6/16 blue eyes, right-handed 2/16 blue eyes, left-handed 6/16 brown eyes, right-handed 2/16 brown eyes, left-handed c. Parents: brown eyes, right-handed blue eyes, left-handed Offspring: 1/4 brown eyes, right-handed 1/4 brown eyes, left-handed 1/4 blue eyes, right-handed 1/4 blue eyes, left-handed
In humans, the ability to roll the tongue is a dominant trait (R), while the inability to roll the tongue is recessive (r). Imagine two parents, both of which are heterozygous, decide to have a child. Create a Punnett square to determine what percentage of their children would be able to roll their tongues.
In rabbits, black hair is dependent on a dominant allele B, and brown upon arecessive allele b. Short-hair is due to dominant allele S and long hair to arecessive allele s. If a true-breeding black short haired male is mated with abrown, long-haired female, what will their offspring look like? What will be the genotypes of the offspring?
Scurs is an example of a sex-influenced traitin cattle that is dominant in males and recessive in females.A male and a female, neither of which has scurs, producea male offspring with scurs. What are the genotypes of theparents?
Draw a Punnett square for a genetic cross of two heterozygous, black-coated dogs. What are the phenotype and genotype ratios of their offspring?
In fruit flies, the allele for long wings (L) is dominant to the allele for short wings (l). If a male that is heterozygous for wing length mates with a female that has short wings what are the possible genotypes and phenotypes of their offspring? Complete the Punnett square below. What is the expected phenotypic ratio among the offspring?
In pea plants, yellow seed color is the dominant trait, and green-seed color is the recessive. Use a punnett square to show the results pf a cross between a heterozygous yellow-seed plant and a green-seed plant.
draw a Punnett square with three different squares of three different traits?
Roan color in cattle is the result of incomplete dominance between red and white color alleles (R/r) of a single gene that controls coat color. How would one produce a herd of pure-breeding roan-colored cattle? Choose an answer below: Cross roan with roan animals Cross red with white animals Cross roan with white animals Cross roan with red animals It cannot be done.
