The correct answer would be YYRR:2YYRr:2Yyrr:4YyRr:YYrr:2YyRR:yyRR:2yyRr:yyrr (last option). Gametes produced by each parent = YR, Yr, yR, and yr. The cross is shown in the figure attached.Jun 12, 2017
Which cross will yield four phenotypes in the 1111 ratio?, Answer. The cross which yields four phenotypes in the 1:1:1:1 ratio is RrYy x rryy.
Furthermore, Which cross will yield four phenotypes?, The answer is RrYy x rryy. So, the ratio is 2:2 or 1:1. The same ratio is for cros Yy x yy. Thus, the cross between RrYy and rryy will yield four phenotypes in the 1:1:1:1 ratio.
Finally, When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be _____?, Answer Expert Verified. When neither gene in a genotype pair is dominant and neither gene is recessive, the genes are said to be incomplete dominant alleles. Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely dominant over the other allele.
Frequently Asked Question:
When the alleles of a gene pair are identical they are said to be?
The genotype of homozygous alleles is identical alleles of the gene for a particular trait. The individual can be homozygous dominant or homozygous recessive. Individuals homozygous for a trait are homozygotes. In other words, homozygous alleles are identical for the same characteristic.
When a pair of allelic genes is identical the genes are said to be?
Diploid organisms, for example, humans, have paired homologous chromosomes in their somatic cells, and these contain two copies of each gene. An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene.
When the alleles of a gene pair are expressed differently but neither is dominant to the other they are called?
Incomplete dominance is defined as. gene pairs occurring in two forms that are expressed differently and neither is dominant to the other. The significance of synapsis during meiosis is that.
What are alleles quizlet?
What are alleles? An allele is an alternative form of a gene (one member of a pair) that is located at a specific position on a specific chromosome. These DNA codings determine distinct traits that can be passed on from parents to offspring.
What term describes one of a pair of genes that controls a certain characteristic?
allele. a member of a gene pair that determines a specific trait. Mendel. Father of Genetics.
When neither of the genes of a pair are dominant nor recessive The genes are said to be?
the situation in which two different alleles for a trait are expressed unblended in the phenotype of heterozygous individuals. Neither allele is dominant or recessive, so that both appear in the phenotype or influence it. Type AB blood is an example. Such traits are said to be codominant.
Which cross will yield four phenotypes in the 1111 ratio?
Answer. The cross which yields four phenotypes in the 1:1:1:1 ratio is RrYy x rryy.
Which cross will yield four phenotypes?
The answer is RrYy x rryy. So, the ratio is 2:2 or 1:1. The same ratio is for cros Yy x yy. Thus, the cross between RrYy and rryy will yield four phenotypes in the 1:1:1:1 ratio.
What are two different genes for the same trait?
These gene variants still code for the same trait (i.e. hair color), but they differ in how the trait is expressed (i.e. brown vs blonde hair). Different versions of the same gene are called alleles. Genes can have two or more possible alleles. Individual humans have two alleles, or versions, of every gene.
Which cross will yield four phenotypes in the 1111 ratio?
Answer. The cross which yields four phenotypes in the 1:1:1:1 ratio is RrYy x rryy.
When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be?
Answer Expert Verified. When neither gene in a genotype pair is dominant and neither gene is recessive, the genes are said to be incomplete dominant alleles. Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely dominant over the other allele.
