Some organisms require only one parent to make a clone of themselves. What is the name for this type of reproduction? Describe their DNA in comparison to its parent's DNA.

asexual reproduction: it will be an EXACT copy of DNA from the parent

sexual reproduction

Julia saw a robin raising 2 blue jay chicks. Julia now thinks that it is possible for a robin to be a biological parent to blue jays. Is Julia's assumption correct? a. No, it is not possible because a robin can only pass robin genes on to its offspring. b. Yes, it is possible for one species of animal to give birth to another species. c. No, it is not possible because robins do not like blue jays. d. Yes, it is possible if the robin's mated with a blue jay.

a. No, it is not possible because a robin can only pass robin genes on to its offspring.

b. tissue

Does a genetic mutation guarantee that there will be a genotypic change? What about a phenotypic change? Why or why not?

Genotypic: Yes, a letter will be mistakenly copied or deleted, which changes the gene letters in our DNA. 

Phenotypic: No, a 1-letter difference may still result in coding for the correct protein, which would not change anything phenotypically. Another reason: many parts of the DNA are never actually read or do anything-- if the mutation happens there, it does not affect anything Phenotypically.

In a certain breed of cats, having black hair is the result of 2 dominant alleles for hair color (HH). The heterozygous genotype (Hh) produces a cat that has black and white spots. Having 2 recessive (hh) genes results in a white-haired cat. The Punnett square below shows the results of a cross between which 2 cats? a. a black cat and a spotted cat b. 2 spotted cats c. 2 black cats d. a spotted cat and a white cat

a. a black cat and a spotted cat

Arial's home is sprayed with a pesticide to control an insect pest. She didn't see any of the insects for a long period of time, but eventually she begins to see insects again. The next time the exterminator sprayed her house, they used the same pesticide, and it had no effect on the insect pest. What is the best way to explain this change in survivorship of the pests' population? a. The original insect population did not pass on their genes to their offspring. b. The insects learned to avoid the pesticide. c. The insects with pesticide-resistant traits survived and reproduced. d. The original insect population ws not very diverse.

c. The insects with pesticide-resistant traits survived and reproduced.

Both of Tim's parents have brown eyes, but Tim has blue eye. How is this possible? a. The characteristic (blue eyes) is carried in a recessive gene b. Eye color is not a genetic trait. c. This characteristic (blue eyes) must be carried in the dominant gene. d. all of these.

a. The characteristic (blue eyes) is carried in a recessive gene
