Answer:
A maple tree is an example of a tree
Answer:
smooth was dominant over that for wrinkled
Explanation:
In complete dominance, a gene may have two different variants or 'alleles', dominant and recessive. A dominant allele is a gene variant that is able to produce a certain phenotype, even in the presence of other alleles, while a recessive allele is a gene variant that is masked by the dominant allele in heterozygous individuals (i.e., individuals that inherited different alleles from each parent). By crossing smooth and wrinkled pea plants, Mendel observed the offspring (F1) were smooth rather than mixed, indicating one type of seed texture was dominant over the other. Subsequently, Mendel observed that alleles for different traits (e.g., seed texture and seed color) assorted independently during meiosis.
Answer:
The correct answer is - C. Spring tides
Explanation:
Spring tides are the highest tides that made in the case when the sun, earth, and the moon all three come in a line. This takes place before the full moon or new moon. The tides occur due to the gravitational pull of the sun and the moon.
The spring tides are the highest tides whereas neap tides are the smallest tides caused by the pull of the sun and moon together on earth.
The researchers will use mice instead of opossums or humans to determine whether the cells of the ear bones originated from the same embryonic cells as the cells that form the jaw in other vertebrates because in this type of experiment, organisms that are ideal are the ones that have a short life span, easy to be researched on and easy to mantain.
It will be very tedious and demanding to use opossums and humans in this type of practical experiment because,it is against the culture and norms guilding human living and existence to use humans as model organisms,opossums as well are very bad model organisms because unlike the mice,opossums are long lived and it will be very difficult to raise and maintain an opossum in a laboratory.
Humans and mice are both mammals just that human is a higher mammal but they share similar features in terms of pattern of development,though there is a clear difference during their early development,so because of the common ancestry shared by the mice and humans,the result of the experiment on the mice with share a close similarity with the pattern that is expected in humans.
Answer:
The correct answer is -50%
Explanation:
Polydactyly is a dominant trait where a person gets an extra finger or toes the dominant allele is represented by P = allele for polydactyly, and the recessive allele represented by p = normal allele
So, the heterozygous woman will be - Pp & the normal man will be - pp. The presence of one allele of polydactyly will be able to show its effect as it is dominant.
Cross between heterozygous woman & normal man:
Gametes:
P p
p Pp (Show polydactyly) pp (Normal phenotype)
p Pp (Show polydactyly) pp (Normal phenotype)
From the above Punnett square, the probability of an offspring that has extra fingers or toes will be 1/2 or 50%.
