What offspring would result from a cross of a homozygous red-eyed female fruit fly and a vermilion-eyed male fruit fly?
When Morgan mated a white-eyed male fruit fly with a red-eyed female fruit fly, the first generation offspring all had red eyes. In the next generation, because females would have the X chromosome for white eyes, about half the offspring would have white eyes. The offspring with white eyes were all male, meaning he discovered eye color in fruit flies showed a sex-linked trait.
The result of this was a generation of red eyed and white eyed individuals. If the red eyed female was heterozygous, this is possible.
What else can I help you with?
Why is this important each of the haploid sex cells has only half the number of chromosomes as the original diploi d cell?
Gametes (or sex cells) are haploid in nature. This means they have half the number of chromosomes present in a regular body cell (or somatic cell). The male and female gametes unite in a process called fertilization to give rise to the offspring. Since both the male and female gametes have haploid number of chromosomes, the final offspring will end up having the diploid number of chromosomes.
Why does sexual reproductive cycle called?
The sexual reproductive cycle is called so because it involves the fusion of male and female gametes (sperm and egg) to produce offspring with a combination of genetic material from both parents. This process is essential for the continuation of the species and allows for genetic diversity among individuals.
Is Hurricane Eunice a female or male?
Hurricane names alternate between male and female. In the case of Hurricane Eunice, it would fall under the female category.
Is a beefalo fertile or infertile?
A beefalo is a hybrid animal resulting from the crossbreeding of a domestic cow and a wild American buffalo (bison). While individual cases may vary, beefalos are generally capable of reproducing and are fertile.
What is internal development?
Internal development refers to the growth and improvement of a company's existing resources, operations, and capabilities to enhance productivity, efficiency, and competitiveness. This can include investments in employee training, process optimization, technology upgrades, and innovation to drive sustainable growth and meet organizational goals.
What is the ratios for a heterorozygous female and a homozygous dominant male?
The offspring will inherit one dominant allele from the homozygous dominant male and have a 50% chance of inheriting the dominant allele from the heterozygous female. Therefore, the ratio of offspring with the dominant allele to those without will be 1:1.
What is the genotype and phenotype ratios for a homozygous dominant female and a homozygous resessive male?
When a homozygous dominant female (genotype AA) is crossed with a homozygous recessive male (genotype aa), all offspring will inherit one dominant allele from the mother and one recessive allele from the father, resulting in a genotype of Aa for all offspring. The phenotype ratio will show all offspring displaying the dominant trait. Thus, the genotype ratio is 100% Aa, and the phenotype ratio is 100% expressing the dominant trait.
If the male parent has the genotype AAA and the female parent has the genotype AAA offsprings genotype will be?
The offspring's genotype will be AA. Both parents are homozygous dominant, AA, having only dominant alleles to pass on to their offspring. So each parent can pass on only the dominant allele (A) to its offspring. So the offspring will also be homozygous dominant, AA.
A female quinea pig homozygous dominant for black fur color is mated with a male homozygous for white fur In a litter of eight offspring there would probably be?
To answer this, first determine the genotypes of the parents. The female is homozygous dominant, which means it carries two copies of the black allele (which we will designate B), so its genotype we can represent as BB. The male is homozygous for the recessive trait (white, designated as b), so its genotype can be represented as bb. So the cross looks like this: BB X bb Next, we must determine the types of gametes each parent can produce. In this case it's easy, because both are homozygous. The female can only produce B gametes, while the male can only produce b gametes. Since the offspring carry one allele from each parent, all of the offspring can have only one genotype: Bb. Since black (B) is the dominant allele, and every offspring carries the dominant allele, all eight of the offspring from this cross will be black.
What would The combination for female offspring be?
The combination of a female offspring would be XX
What are your female offspring called?
Female offspring are commonly referred to as daughters.
Mules are the offspring from female horses and male?
They are the offspring of female horses and male donkeys.
Which gender can have white eyes if the female parent is homozygous dominant for red eyes and if the male parent has white eyes?
The offspring will have red eyes because the mother is homozygous dominant for red eye color. White eye color is a recessive trait and can only be expressed when both parents pass on the white allele. Since the father has white eyes, the male offspring will inherit the white eye color.
What percentage of the offspring is female?
50% of the offspring are female. Gender determination in offspring is typically governed by a 50/50 chance.
What is approximate probability that a human offspring will be female?
50%, or half. Therefore, there is an equal chance that the offspring will be female.
What is a young female bovine that has not had offspring yet called?
A young bovine that has not had an offspring is called a heifer.
What is a X linked carrier homozygous?
An X linked carrier is one who carries a mutation in a gene found on the X sex chromosome. A carrier of the trait doesn't display phenotypic symptoms of the disease or mutation but can transfer the mutation in that gene to their offspring (ex: the carrier of a premutation that when transferred to the offspring via the X chromosome will cause the full mutation associated with that gene). A person could be a homozygous carrier if for instance, she were female (two X chromosomes) and carried the premutation associated with the disease. Some diseases need both alleles of the gene to be mutated. If only one allele is mutated (heterozygote) that person may be a carrier for that mutation and can thus pass on that mutation to their children.
