Sexual Motivation

Sexual motivation refers to a person's overall desire for sexual activity. It is an unusual motivation. Generally, among lower animals, the term 'drive' is commonly referred to as sexual motivation. It means a certain internal force drags the animal to be involved in reproductive behavior. On the contrary, humans are not simply driven by any internal force; rather, the sexual motivation in humans is due to several factors such as biological (hormones, genes), environmental (familial upbringing, chemical exposure) and physiological factors (culture, desire) which further determine engagement in sexual activities.

Question

Problem 7
In chickens, a dominant hereditary abnormality (e.g., creepers) causes death when the genotype is
homozygous (CC). The recessive condition (cc) at this locus produces a normal phenotype.
Another gene locus with co dominant alleles is known to govern feather color such that the
genotype FF = black, ff= splashed white, and Ff = blue. Also, a completely dominant gene W
produces white skin. Yellow skin is produced by the homozygous genotype ww.
a. In CcFfWw x CcFfWw, what proportion of the live progenies is
a.l Ceffww
a.2 normal, blue feathered, white skinned
a.3 ccFfWw
a.4 carriers of the lethal gene
a.5 white feathered, yellow skinned creepers
b. In CCFFWW x ccffWw, what proportion of the offspring is
b.1 ccFfww
b.2 normal, white feathered, white skinned
b.3 yellow skinned

In chickens, feathered legs are produced by a dominant allele F. Another allele f of the same gene produces featherless legs. The dominant allele P of a gene at a different locus produces pea combs; a recessive allele p of this gene causes single combs.

Practice Pedigree Problem help. I am confused so please show. Label Phenotypes and genotypes as you go about the Pedigree (and whatever else might be required)! Thank you again for your help, these questions confuse me). Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individuals which are heterozygous for these alleles are calico or tortiseshell in color. a). If a long-haired, black male is mated with a calico female homozygous for short hair, what kind of kittens will be produced in the F1generation? Give both genotypes and phenotypes; express the genotypes both symbolically and in words.
