If there are two different alleles for a trait, this means t<span>he trait could show up in two different forms.</span>

Answer:

The correct answer would be B. The trait could show up in two different forms.

Alleles refer to the alternative forms of the gene. Different alleles of a gene code for different traits in an organism.

For example, T codes for tallness and t codes for a dwarf. Similarly, R codes for round seed shape and r codes for wrinkled seed shape et cetera.

Based on the expression levels, the alleles can be of two types recessive and dominant.

The allele which expresses itself in a heterozygous condition is said to be a dominant allele and the allele which is masked in heterozygous condition is said to be a recessive allele.

Question 12 of 20 :
daser333 [38]
A; Carbon’s atomic number is 6, atomic number indicates the amount of protons in an atom. The number of protons (positively charged particles) is equal to the number of electrons (negatively charged particles). Because atoms have a neutral charge. The average atomic mass of carbon is 12.011; this is the amount of protons plus the amount of neutrons because electrons are so small they weigh almost nothing compared to protons and neutrons. To find the number of neutrons you subtract the number of protons from the average atomic mass. 12.011-6=6.011 (which can just be rounded to 6). So a carbon atom has 6 neutrons. Answer A is correct because it correctly states that an atom of carbon has 6 protons 6 neutrons and 6 electrons

Describe the events that occur during meiosis that are defined by Mendel's laws of segregation and independent assortment. Expla
zysi [14]

Answer:

Mendel's Laws are a set of basic rules on the inheritance of characteristics from parent organisms to their children. They are considered rules rather than laws, since they are not fulfilled in all cases. Mendel's first Law of equitable segregation establishes that during the formation of the gametes each allele of a pair is separated from the other member to determine the genetic constitution of the filial gamete, the two alleles, which code for each characteristic, are segregated during the production of gametes through meiotic cell division. This means that each gamete will contain only one allele for each gene. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation. For each characteristic, an organism inherits two alleles, one for each relative. This means that in somatic cells, one allele comes from the mother and one from the father.

Explanation:

Mendel's laws reflect chromosomal behavior during meiosis: the first law responds to the random migration of homologous chromosomes to opposite poles during anaphase I of meiosis (both alleles and homologous chromosomes segregate equally or 1: 1 in gametes) and the second law, to the random alignment of each pair of homologous chromosomes during metaphase I of meiosis (whereby different genes and different pairs of homologous chromosomes segregate independently).Even though not all genes are inherited in the proportions described by Mendel, they are undoubtedly all inherited in the same way, that is, the alleles or different alternatives of a gene are separated in meiosis and each gamete will carry only 1 of them (2nd Mendel's Law) and in turn all genes on different pairs of chromosomes are transmitted independently. This allows the maternal and paternal alleles to combine in the offspring, ensuring genetic variation.Therefore, of each possible genotype for a two three or more genotypes it is possible to know how many gametes it will form, in what proportions and therefore predict results of crosses.

Is natural gas found in equal amounts around the globe? Why or why not?
Masja [62]
No, it's found in many different amounts. It's obvious that you find different amounts of it in different places that you go.
