Answer:
1. tall (or heterozygous)
2. 3:1
3. carriers
4. Each parent organism contributes one copy of its alleles in a seemingly random fashion to its offspring, as meiosis to create gametes (egg or sperm cells) reduces the number of genes by half. Therefore, each gamete contributes only one allele.
5. A Punnett square is a diagram used to map out the possible genotypes of a child given the genotypes of its parents. In a Punnett square, the genotype of one parent is listed in the first row of the square, and the genotype of the second parent is listed in the first column. Then, in the middle squares, all possible genotypes of their offspring are listed, and the phenotypes are calculated using the law of dominance.
6. Purebred strains of organisms always produce heterozygous offspring in the first generation, with all members of the first generation exhibiting the dominant trait for the gene of interest. The second generation typically has a 3:1 mix of dominant and recessive phenotypes, respectively.
7. Punnett squares predict that the second generation of two distinct purebred homozygotes for a trait will have a 3:1 ratio of dominant to recessive traits. Mendel did careful statistical analysis on his hybridization experiments and found that, for each of his seven characteristics of interest, the ratio was approximately, but not exactly, 3:1. Therefore, Mendel's experimental observations match the predictions of Punnett squares quite well.
Explanation:
The answer to this question is Paradoxical sleep.
Paradoxical sleep is the stage of sleep where in the person’s muscles are
relaxed and this is the stage that is called a dreaming sleep. In this stage of
sleep the person is in deep sleep state.
Answer:
Well it only makes sense that he meant that since humans use the oceans for so much once they are gone, humans will die not too long after
Explanation:
D) all of the above are potential disadvantage for the use of adult stem cells.
I hope this helps you. ☺
Production of sperms is referred as spermatogenesis and production of ovum or egg is called oogenesis. Spermatogenesis and oogenesis are similar in a way in humans as bth these processes produce large numbers of sperms and eggs. Spermatogenesis is a continuous process where large numbers of sperms are produced at once and uses less energy. Ovulation is a process where only one egg or ovum matures at a time requires more energy. Not all the egg cells mature in females.
