Concept explainers

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Question

and donkeys can clearly interbreed, so why are they not considered to be
members of the same species? *
They look different
They occupy different ecosystems

Honeybees are unusual in that male bees (drones) have only onecopy of each gene, but female bees have two copies of their genes.This difference arises because drones develop from eggs that havenot been fertilized by sperm cells. In bees, the trait of long wingsis dominant over short wings, and the trait of black eyes is dominant over white eyes. If a drone with short wings and black eyeswas mated to a queen bee that is heterozygous for both genes, what are the predicted genotypes and phenotypes of male and femaleoffspring? What are the phenotypic ratios if we assume an equalnumber of male and female offspring?
A recessive allele in mice results in an unusually long neck. Sometimes,during early embryonic development, the long neck causesthe embryo to die. An experimenter began with a population oftrue-breeding mice with normal necks and true-breeding mice withlong necks. Crosses were made between these two populations toproduce an F1 generation of mice with normal necks. The F1 micewere then mated to each other to obtain an F2 generation. For themice that were born alive, the following data were obtained:522 mice with normal necks62 mice with long necksWhat percentage of homozygous mice (that would have had longnecks if they had survived) died during embryonic development?

In 1981, a stray black catwith unusual rounded,curled-back ears was adoptedby a family in California.Hundreds of descendants ofthe cat have since been born,and cat fanciers hope to develop the curl cat into a showbreed. Suppose you ownedthe first curl cat and wantedto develop a true-breeding variety. How would you determinewhether the curl allele is dominant or recessive? How wouldyou obtain true-breeding curl cats? How could you be sure theyare true-breeding?
If you try to throw a basketball into a basket, the likelihood ofsucceeding depends on the size of the basket. It is more likely thatyou will get the ball into the basket if the basket is bigger. In yourown words, explain how this analogy applies to the idea that thelikelihood of crossing over is greater when two genes are far apartthan when they are close together?

More Crosses with Pea Plants: The Principle of Independent Assortment Think about this one carefully. Albinism and hair color are governed by different genes. A recessively inherited form of albinism causes affected individuals to lack pigment in their skin, hair, and eyes. In hair color, red hair is inherited as a recessive trait and brown hair is inherited as a dominant trait relative to red hair. An albino woman whose parents both have red hair has two children with a man who is normally pigmented and has brown hair. The brown-haired partner has one parent who has red hair. The first child is normally pigmented and has brown hair. The second child is albino. a. What is the hair color (phenotype) of the albino parent? b. What is the genotype of the albino parent for hair color? c. What is the genotype of the brown-haired parent with respect to hair color? Skin pigmentation? d. What is the genotype of the first child with respect to hair color and skin pigmentation? e. What are the possible genotypes of the second child for hair color? What is the phenotype of the second child for hair color? Can you explain this?

Imagine that you went to the pet store and bought two black guinea pigs that are known to be heterozygoues (Bb). You also kno whtat black fur (BB) is dominant over white fur (bb), and a that a lethal recessive allele is located only one cM away from the recessive (b) allele. You decide to start raising your own guinea pigs, but after mating these animals several times, you discover they only produce only black progeny. a) How would you explain this result b) what is the probability of your two black guinea pigs producing white offspring? c) If an average mating produces 10 offspring, how many matings would it take to produce a white offspring?
