Best answer: What is the genotype of this mouse Brainly?

As mouse genotype is stated as Bb, on the chromosome from its parents, allele B comes from one parent while allele b is inherited from the other parent. Phenotype is the expressed trait. In this case, as genotype has allele B, the phenotype will be brown fur as its effect is expressed.

What is the genotype of the white mouse?

Mice with genotype cc are albino because all pigment production and deposition of pigment in hair is blocked. … A mouse with a black agouti coat is mated with an albino mouse of genotype bbcc. Half of the offspring are albino, one quarter are black agouti, and one quarter are brown agouti.

Which of the following is true about the genotype of this mouse?

Answer: The correct option is D) The mouse must be ff. Explanation: A dominant trait arises due to a dominant allele.

Which words describe the genotype of a mouse that inherits two of the alleles for white fur?

Answer: A mouse that inherits two alleles for gray fur would be GG. Assuming that captial G indicates the dominant alleles, the words to describe the genotype would be homozygous dominant.

What is the chance a mice would be homozygous black fur Brainly?

Hence, 25% of the F2 progeny would be homozygous black.

How do you know if a gene is epistatic?

Epistasis is determined by the self-progeny of the F2 animals. If animals of phenotype A produce progeny of phenotype A and B while animals of phenotype B only produce progeny of phenotype B, gene B is epistatic to gene A. Gene A would be epistatic to gene B if the opposite were true.

What are the 3 genotypes?

Genotype is also used to refer to the pair of alleles present at a single locus. With alleles ‘A’ and ‘a’ there are three possible genotypes AA, Aa and aa.

What is heredity and how it works in mice?

Heredity is the inheritance of genes from parent “mice” to their offspring. An allele is a segment of DNA sequence that controls a particular trait (phenotype). … So if a mother with one genotype mates with a father with another genotype, the offspring has a 50-50 chance of inheriting either genotype.

What is meant by genotype?

In a broad sense, the term “genotype” refers to the genetic makeup of an organism; in other words, it describes an organism’s complete set of genes. Each pair of alleles represents the genotype of a specific gene. … For example, in sweet pea plants, the gene for flower color has two alleles.

How many possible genotypes can the offsprings have?

Figure 13: The possible genotypes for each of the four phenotypes. Even though only four different phenotypes are possible from this cross, nine different genotypes are possible, as shown in Figure 13.
