Answer:
16
Explanation:
A diploid organism that produces gametes will undergo meiosis to do so. Meiosis reduces the chromosomal number in the gametes by half. Hence, each gamete will have 4 chromosomes (haploid,n). Crossing-over will likely occur during the meiotic process leading to recombination in the arrangement of chromosomes in the gametes.
If this occurs, a mathematical expression of 2^n is used to determine the number of possible combinations, where n is the number of chromosomes in the gamete.
Hence, 2^4 = 16 possible combinations of chromosomes in the gamete.
Answer:
Due to vegetative reproduction, his plants are not genetically diverse.
Explanation:
Strawberry plants do not reproduce via sexual reproduction, so we can immediately eliminate the options pertaining to sexual reproduction. Now, we can take a look at the options pertaining to vegetative reproduction.
With vegetative reproduction, the "child" plant has the same genetic makeup as the parent plant. If this happens over and over, then the offspring will not be genetically diverse. Either all of the strawberry plants or none of them would be fungi-resistant. The farmer did not find any fungi-resistant plants because they all have the same genes, and therefore all do not have the genes that would make them fungi-resistant.
Answer:
its called a membrane
Explanation:
its kind of like a cell wall
One reason i could have a negative affect is that the wildlife there would have no chance to relocate. Another is that it could cause a shortage in food for the prey type animals thinning their population witch in turn would kill off predatory animals and would through the whole ecosystem off balance. Hope it helps :).
Answer:
X-linked/Sex-linked recessive inheritance
Explanation:
<em>The most likely mode of inheritance of the trait is an X-linked recessive inheritance.</em>
The sex chromosome of a male is XY while that of a female is XX. The Y chromosome is hypothesized not to carry any allele ordinarily. Hence, a male child only needs to inherit one affected allele to become affected for recessive X-linked traits.
During gamete formation, the sex chromosome of the male segregates into X and Y gametes while that of the female segregates into X and X gametes. During fertilization, the X gamete of the male is usually inherited by the female while one of the X gametes of the female is usually inherited by the male.
<u>Assuming a father is affected for an X-linked recessive trait, the affected X chromosome will be passed to a female child and such a child would be a carrier, rather than being affected since she requires the two X chromosomes to be affected in order to exhibit the trait. </u>
<u>The affected X chromosome is thus passed to her male child according to the law of inheritance of the sex chromosome. Hence, the grandson of the affected man inherits the trait through the daughter of the affected man.</u>
