The answer is; deletion mutation


This type of mutation mostly causes a phenomenon called frameshift mutation whereby the 3-codon sequence reading frame is shifted causing the amino acids translated, downstream of the deletion site, to be altered. This can gravely affect the function of the translated proteins and result in genetic disease.

nekit [7.7K]

Answer:

C

Explanation:

Assume that allele A is the dominant allele that produces the dominant phenotype (tall) in plants that have at least one allele A, and allele a is the recessive allele that produces the recessive phenotype (short) in plants that have two alleles a.

In the parental generation, a true-breeding tall plant has the AA genotype (phenotype: tall), and a true-breeding short plant has the aa genotype (phenotype: short).

We have the Gregor Mendel's cross as in the image attached here.

All of the F1 generation (offspring plants) have the Aa heterozygous genotype, and therefore, they are all tall.

The answer is c (the offspring plants have a genotype that was different from that of both parents).

In a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fr
juin [17]

Correct option(s):

(b) This muskmelon plant's genotype for the fruit taste gene is ff.

(c) This muskmelon plant is homozygous for the fruit taste gene.

A dominant allele is one that is capable of expressing itself even in the heterozygous condition and overshadows the effect of the recessive allele. It is usually denoted by a capital letter. Recessive allele on the contrary cannot express in presence of a dominant allele and is denoted by a small letter.

In the given case the fruit with a sour taste (phenotype) can have two possible genotypes (FF and Ff). The genotype of sweet taste is ff which is a homozygous condition.  

Note: Your question is incomplete, probably your complete question is “In a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fruit taste trait has two alleles. the allele F is for sour fruit, and the allele f is for sweet fruit. a certain muskmelon plant from this group has sweet fruit. this plant has two alleles for sweet fruit. Choose the correct option:

(a)  this muskmelon plant's genotype for the fruit taste trait is sweet fruit.

(b) this muskmelon plant's genotype for the fruit taste gene is ff.

(c) this muskmelon plant is homozygous for the fruit taste gene.”
