Q.19 - Asexual reproduction introduces less genetic variation for natural selection to act on.
[Note: More variations are produced by natural selection which ensure survival of a species.
The new offspring has characteristics of both parents.]
Q.20 - Yes, because they are eterozygous, they must have one allele for A, and for O. So there is a 25% chance that a child would have the blood type O.
QUESTION 19 Compared to sexual reproduction, asexual reproduction can be a disadvantage in a changing environment,...
QUESTION 20 2 parents have the blood type A both are heterozygous for this blood type. Can they have a baby with blood type 07 No, if both parents have blood type A, there is no chance that their child could have any other blood type, Yes, if their chromosomes do a crossover and recombine into blood type 0. O yes, because they are heterozygous, they must have one allele for A, one for O. So there is a 25%...
According to an idea called the Red Queen hypothesis, sexual reproduction is favored over asexual reproduction when pathogens are present because it increases genetic diversity, allowing some of the host offspring to escape the pathogen. Some researchers were interested in testing this idea in aphids which can reproduce both asexually and sexually. In this study, the researchers measured rates of fungal infection and frequency of sexual reproduction across many populations to see if these two variables were related. It was...

How is genetic variation increased during sexual reproduction? Choose ALL that apply. Select one or more: a. Crossing over occurs. b. The reproduction of cells through binary fission resulting in two different daughter cells. c. Independent assortment of homologous chromosomes during meiosis. d. Alleles are inherited from two parents instead of one. e. The pairing of sister chromatids. Which of the following images shows crossing over? Select one: Consider a gene with two alleles that show complete dominance. When two...
need help with this .. From the pages 571-587 attached below. 1a) Suppose a population of guppies was infected with a parasite. In that population a mutation results in a parasite resistant genotype that spreads through the population through natural selection. A subsequent mutation in the parasite results in a genotype that is unaffected by the newly evolved resistant guppy genotype. What is the name of the hypothesis that explains this host parasite “arms race”.? 1b) What is this name...
1. For each of the following blood types, list the possible genotypes: Phenotype Possible Genotypes A B AB O 2. Dr. Paul is blood type O. His father was blood type A and his mother was blood type B. What were the genotypes of his parents? What are the possible blood types and phenotypic ratios expected for a cross involving these parental genotypes? 3. In the ABO blood system in human beings, alleles A and B are codominant and both are...
T/F: Human blood type has 6 genotypes. T/F: If albinism is a recessive trait and 2 carrier parents mate, they have a 25% chance of having 1. 2. an albino child. 3. 4. 5. 6. 7. 8. 9. 10. T/F: The sex of an individual does not affect patterns of inheritance for most traits. T/F: Genes are segments of RNA that code for proteins T/F: Wavy hair is an example of incomplete dominance. T/F: If a man has normal color...

the two cream colored guinea pigs produced, in one case, 22 yellow. 47cream, and 19 white. What type of inheritance is this? II. Sex-linked Characteristics 12. In man, colorblindness, an inability to distinguish between red and green, is inherited as a sex-linked character on the X chromosome. It is recessive. If a colorblind man marries a homozygous normal woman what chance is there for the children of being colorblind? If a normal man marries a colorblind woman. where will colorblindness...
