Answer: A genotype is an individual's collection of genes.
Explanation:
Answer:
Manatees are considered tetrapods due to tetrapod ancestor.
Explanation:
Manatees are considered tetrapods even though they lack hind limbs because they are the descended of the tetrapod common ancestor. The oldest ancestors of manatees were pig-like, four-legged animal that lives on land and eats grass but when some of them start living in the water so with the passage of time their hind limbs disappear because there is no need of these legs in water. So due to link with the four-legged animal manatees are considered tetrapods.

Plants that have many periods of reprodution are called perrenials.

Answer:
B) 50%
Explanation:
Recessive alleles need two be present in both homologous chromosomes to express and to observe the phenotype they determine in the individual.
The possible genotypes and phenotypes for fur pigmentation in tigers are:
- aa: white
- Aa: normal
- AA: normal
The phenotypically normal heterozygous tiger is <em>Aa</em> and is crossed with a white tiger <em>aa</em>.
The Aa tiger produces 1/2 <em>A</em> gametes and 1/2 <em>a.</em> The aa tiger only produces <em>a</em> gametes.
<u>The possible offspring resulting from the combination of those gametes is:</u>
- 1/2 Aa: normal
- 1/2 aa: white
So 1/2 = 50% of the offspring will be white.
Answer:
heritability
Explanation:
Heritability is a measure of the contribution of genetic differences among the individuals to their phenotypic differences. Individuals differ from each other in one or other phenotypic or morphological traits. These differences might be a result of differences in their genes or may be due to differences in their environment. Heritability measures how much the phenotypic differences among the individuals can be correlated to their differences in the genes.
