In Texas Longhorn cattle, coat coloration is an inherited trait. What is the genetic basis of coat-color variation in Texas Longhorn cattle? ResponsesDifferences in the numbers of chromosomes in cellsDifferences in the numbers of chromosomes in cellsDifferences in the diets of individual cattleDifferences in the diets of individual cattleDifferences in the environmental conditions of different geographic areasDifferences in the environmental conditions of different geographic areasDifferences in the nucleotide sequences of genes

In a population of cows, some individuals have a black coat and others have a red coat. The gene for coat color has two possible alleles. One allele is for a black coat (B), and the other allele is for a red coat (b).A certain cow in the population has the genotype bb for the coat color trait.Which term best describes this cow’s genotype?Choose 1 answer:Choose 1 answer:(Choice A)   homozygousAhomozygous(Choice B)   heterozygousBheterozygous

Indian paintbrushes, a Texas wildflower, vary in color from scarlet to orange, cream, yellow and occasionally purple. Flower color is an inherited trait. What is the basis for the variation in the color of the flowers in this species of plants?Select one:a.The difference in the number of chromosomes in each variety of plantsb.The nutrients in the soil where plants grows in Texasc.The order of the nitrogenous bases in the DNAd.The climate and region the plant grows in Texas

Two cows are living on a ranch. One cow is much larger and more muscular than the other.Which of the following best describes a genetic factor that could have led to the cows’ different traits?Choose 1 answer:Choose 1 answer:(Choice A)   The larger cow has access to more food than the smaller cow does.AThe larger cow has access to more food than the smaller cow does.(Choice B, Checked)   The smaller cow has brown patches on its fur, and the larger cow has black patches.BThe smaller cow has brown patches on its fur, and the larger cow has black patches.(Choice C)   The cows are different breeds, so they have different genes affecting their growth.CThe cows are different breeds, so they have different genes affecting their growth.

Palomino (golden brown) horses are bred for their coat coloration.  A breeder will achieve 100% Palomino offspring by crossing a chestnut (dark brown) horse with a cremello (cream) horse.  However, if a breeder crosses two Palomino horses, only 50% of the offspring will be Palomino, while 25% will be chestnut and 25% will be cremello.  Genetic inheritance of coat color in these horses is best described as:A.codominance.B.complete dominance.C.variable expressivity.D.incomplete dominance.

12. The coat colour in rabbits is controlled by one gene with four alleles. The gene is found on an autosome. The symbols for the alleles are shown below.F — black or brown colourFch — chinchilla colouration (greyish colour)Fh — Himalayan colouration (white body and dark ears, face, feet and tail)f — albino (white colour)The number of copies of the gene in each rabbit would be1 point1234
