Summary Introduction
Introduction:
An organism’s genotype is the number of different alleles for a particular trait present in it. If the organism carries the same type of allele for a particular type of gene, it is homozygous for that particular gene. If it carries two different type of allele, it is heterozygous for that gene.

- An organism that has two different alleles for a single trait is said to be for that trait. Select one: O O O a. heterologous b. heterozygous c. homozygous d. haploid e. diploidarrow_forwardThe father has curly hair; the mother has also curly hair. Will it be possible for their offspring to have straight hair since both parents are curly? a. No, it is very impossible to have a child with straight hair. b. Yes, it is possible for their offspring to have straight hair if the mother also has black hair. c. Yes, all of their offspring will have straight hair. d. Yes, the parents will have offspring with straight hair if the parents are heterozygous for traits. e. Yes, the parents will have offspring with straight hair if the parents are homozygous for the trait.arrow_forwardHoney Bees are unusual in that male bees (drones) have only one copy of each gene, while female bees have two copies of each gene. That is because drones develop from eggs that have not been fertilised by sperm cels. In bees, the trait of long wings is dominant over short wings, and the trait of black eyes is dominant over white eyes. If a drone with short wings and black eyes was mated to a queen bee that is heterozygous for both genes, what are the predicted genotypes and phenotypes of male and female offspring. What are the phenotypic ratios if we assume an equal number of male and female offspring?arrow_forward

If the couple has four children, what is the probability that they will have three normal daughters and one normal son?arrow_forwardIn a certain breed of dogs, a gene (L) codes for hair length. The dominant trait is short hair and the recessive is long hair. Suppose a heterozygous female dog and a homozygous recessive male dog mate. What is the male dog’s genotype and the female dog’s genotype? What is the male dog’s phenotype and the female dog’s phenotype? What will be the genotypic ratio for the offspring from these dogs? What will be the phenotypic ratio for the offspring from these dogs?arrow_forwardWhich statement about the pattern of inheritance for a recessive X-linked allele is true? A.
