The genotype of children in the given case. Introduction: The genotype of the parents can be used to determine the genotype of the offspring. Mendelian genetics can be used to predict the genotype. Given case has taken two traits into consideration thus there are two pair of genes involved. The alleles of the parental genes combine in various ways to create new allelic pairs.

Question

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.

A genotypic ratio of 2:4:2:2:4:2 is possible between a male who is heterozygous free earlobes and heterozygous freckles, and a female who is homozygous free earlobes and heterozygous. Free earlobes is a dominant trait. Key: E = free earlobes e = attached earlobes F = freckles f = no freckles ○ If the first statement is FALSE and the second statement is TRUE O If both statements are TRUE If the first statement is TRUE and the second statement is FALSE O If both statements are FALSE

Use the Punnett square to find the genotype of the missing parent. Having freckles is dominant (F) and having no freckles is recessive (). Curly hair is recessive (c) and straight hair is dominant (C). A man with curly hair marries a woman who is homozygous dominant for straight hair. Complete the Punnett square. What is the probability they will have a child with curly hair? Straight hair? FF Ff f Ff ff % curly % straight

Imagine that a couple is planning to have children. The male is heterozygous for Huntington’s disease and homozygous dominant for Tay-Sachs. The female is homozygous recessive for Huntington’s disease and heterozygous for Tay-Sachs. The couple is curious about the possibility and probability of their offspring inheriting Tay-Sachs and/or Huntington’s. For humans, Huntington’s disease is dominant (H) over the “normal” condition (h), and the “normal” condition is dominant (T) over Tay-Sachs (t). Complete a Punnett square for this cross and record the probabilities for genotypes and phenotypes of the offspring as ratios.
