Answer:
A) CcSs
Explanation:
In order to have all of the combinations both parents must have both dominant and recessive alleles for both traits. This is because the only time a recessive phenotype appears it must have two recessive alleles for that trait (genotypes such as ccss, or ccSS/ccSs if just recessive color, and CCss/Ccss if just recessive spots)
The type of fertilization that one would expect to find in this specie is EXTERNAL FERTILIZATION. External fertilization is the type of fertilization in which the male sperm fertilize the female eggs out of the female's body. This type of fertilization usually occur in aquatic environment.
Answer:
i think the answer would be D
Answer:
r-selected species (e.g., American bullfrog)
Explanation:
The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).
Answer:
The cross is as follows:
P: D/d × d/d
Explanation:
Half of the F1 progeny are mutant. The mutation results in 3 cotyledons is dominant and the original mutant is heterozygous.
If D denotes the mutant allele and d denotes the wild type allele.
The cross is as follows:
P: D/d × d/d
F1 denotes D/d three cotyledons
d/d denote two cotyledons
