Yes, it is possible.
In this case both of the parental plants were heterozygotes and they manifested dominant allele in their phenotype, which is round seed.
P: Aa x Aa
F5: AA, Aa, aA, aa - possible genotypes in fifth generations.
A- dominant allele (round seeds); a- recessive allele (wrinkled seeds)
Wrinkled phenotype is manifested only if there are two recessive alleles present.
I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.
ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA.
iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.
51.5- AB
Since in the ABO blood system AB is a blood type as well as B. The rest of the population will have either of these types so exclusively for B type then it will ne the remaining - AB
Answer:
The cell would not split in two
Explanation:
Each daughter cell has the same number and kind of chromosomes as the parent nucleus If mitosis were not accompanied by cytoplasmic division, there would only be one cell with two identical nuclei because the division did not occur for there to be two different cells.
Answer:
Longest interval during which no tree-cutting sample occurred: 9 years (1203 AD - 1212 AD)
First year in that interval: 1203 AD
Explanation:
Lets complete the question first.
Q) A study uses tree rings to determine the year in which a tree was cut. The data is shown in the leaf and stem diagram in the ATTACHMENT.
The three digits number in the left column represents centuries and decades AD. The numbers on the right represents the years.
For example, consider the first input in the diagram
119 | 5 6
which means it represents 2 samples.
1195 AD, 1196 AD.
The longest interval with no tree-cutting samples is found from 1203 AD to 1212 AD.
