Q: horned bull is mated to a hornless cow that is heterozygous for the condition. What kind of…

A: Even when heterozygous with a recessive allele, a dominant allele expresses its phenotypic effect.…

Q: A male Sahiwal (RRHH) is crossed with a female Angus (Rrhh). Where R-Red, r-Brown, H-Horned,…

A: Alleles are the alternative forms of a gene that are located on the same locus of homologous…

Q: Explain the influence of crossing over on phenotypic ratios and genetic diversity in a population.

A: Crossing over is the mixing of genetic material that occurs in the germline. During meiosis, paired…

Q: If we cross a pure red-eyed female rat with a white-eyed male rat, what is the expected ratio of…

A: The red trait is encoded by the gene present on X chromosome. The XR allele encodes red color and it…

Q: draw a Punnett square with three different squares of three different traits?

A: A Punnett square represents phenotype and genotype of the progenies.

Q: heterozygous black furred shirt  whispered mouse is crossed with a homozygous white furred long…

A: Heterozygous means presence of two different alleles for a gene. For example in Aa genotype , "A" is…

Q: What would the phenotypes and the phenotypic ratio be if the F1 individuals produced in a male blue…

A: Heredity is the factor by which the genetic characteristics are passed on from generation to the…

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
